1.	Acosta, Stefan, et al. (författare) Management of Acute Mesenteric Venous Thrombosis : A Systematic Review of Contemporary Studies 2021 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1799-7267 .- 1457-4969. ; 110:2, s. 123-129 Forskningsöversikt (refereegranskat)abstract BACKGROUND AND AIMS: Acute mesenteric venous thrombosis accounts for up to 20% of all patients with acute mesenteric ischemia in high-income countries. Acute mesenteric venous thrombosis is nowadays relatively more often diagnosed with intravenous contrast-enhanced computed tomography in the portal phase than at explorative laparotomy No high-quality comparative studies between anticoagulation alone, endovascular therapy, or surgery exists. The aim of the present systematic review was to offer a contemporary overview on management.MATERIALS AND METHODS: Eleven relevant published original studies with series of at least ten patients were retrieved from a Pub Med search between 2015 and 2020 using the Medical Subject Heading term "mesenteric venous thrombosis."RESULTS: When MVT is diagnosed early, immediate anticoagulation with either unfractionated heparin or subcutaneous low-molecular-weight heparin should commence. Surgeons need to be aware of the importance to scrutinize the computed tomography images themselves for assessment of secondary intestinal abnormalities to mesenteric venous thrombosis and the risk of bowel resection and worse prognosis. Progression toward peritonitis is an indication for explorative laparotomy and assessment of bowel viability. Frank transmural small bowel necrosis should be resected and bowel anastomosis may be delayed for several days until second look. Meanwhile, intravenous full-dose unfractionated heparin should be given at the end of the first operation. Postoperative major intra-abdominal or gastrointestinal bleeding occurs rarely, but the heparin effect can instantaneously be reversed by protamine sulfate. Patients who do not improve during conservative therapy with anticoagulation alone but without developing peritonitis may be subjected to endovascular therapy in expert centers. When the patient's intestinal function has recovered, with or without bowel resection, switch from parenteral unfractionated heparin or low-molecular-weight heparin therapy to oral anticoagulation can be performed. There is a trend that direct oral anticoagulants are increasingly used instead of vitamin K antagonists. Up to now, direct oral anticoagulants have been shown to be equally effective with the same rate of bleeding complications. Patients with no strong permanent trigger factor for mesenteric venous thrombosis such as intra-abdominal cancer should undergo blood screening for inherited and acquired thrombophilia.CONCLUSION: Early diagnosis with emergency computed tomography with intravenous contrast-enhancement and imaging in the portal phase and anticoagulation therapy is necessary to be able to have a succesful non-operative succesful course.
2.	Acosta, S., et al. (författare) Management of Spontaneous Isolated Mesenteric Artery Dissection : A Systematic Review 2021 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 110:2, s. 130-138 Forskningsöversikt (refereegranskat)abstract Background and Aims: There are increasing reports on case series on spontaneous isolated mesenteric artery dissection, that is, dissections of the superior mesenteric artery and celiac artery, mainly due to improved diagnostic capacity of high-resolution computed tomography angiography performed around the clock. A few case–control studies are now available, while randomized controlled trials are awaited. Material and Methods: The present systematic review based on 97 original studies offers a comprehensive overview on risk factors, management, conservative therapy, morphological modeling of dissection, and prognosis. Results and Conclusions: Male gender, hypertension, and smoking are risk factors for isolated mesenteric artery dissection, while the frequency of diabetes mellitus is reported to be low. Large aortomesenteric angle has also been considered to be a factor for superior mesenteric artery dissection. The overwhelming majority of patients can be conservatively treated without the need of endovascular or open operations. Conservative therapy consists of blood pressure lowering therapy, analgesics, and initial bowel rest, whereas there is no support for antithrombotic agents. Complete remodeling of the dissection after conservative therapy was found in 43% at mid-term follow-up. One absolute indication for surgery and endovascular stenting of the superior mesenteric artery is development of peritonitis due to bowel infarction, which occurs in 2.1% of superior mesenteric artery dissections and none in celiac artery dissections. The most documented end-organ infarction in celiac artery dissections is splenic infarctions, which occurs in 11.2%, and is a condition that should be treated conservatively. The frequency of ruptured pseudoaneurysm in the superior mesenteric artery and celiac artery dissection is very rare, 0.4%, and none of these patients were in shock at presentation. Endovascular therapy with covered stents should be considered in these patients.
3.	Ahl, Rebecka, 1987-, et al. (författare) The Association Between Revised Cardiac Risk Index and Postoperative Mortality Following Elective Colon Cancer Surgery : A Retrospective Nationwide Cohort Study 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 111:1 Tidskriftsartikel (refereegranskat)abstract INTRODUCTION: Despite improvements in the perioperative care during the last decades for oncologic colon resection, there is still a substantial risk for postoperative complications and mortality. Opportunities exist for improvement in preoperative risk stratification in this patient population. We hypothesize that the Revised Cardiac Risk Index, a user-friendly tool, could better identify patients with high postoperative mortality risks.METHODS: A retrospective analysis of operated patients between the years 2007 and 2017 was undertaken, using the prospectively recorded Swedish Colorectal Cancer Registry, which has a 99.5% national coverage for all cases of colon cancer. Patients were cross-referenced with the Swedish National Board of Health and Welfare dataset, a government registry of mortality and comorbidity data. Revised Cardiac Risk Index (RCRI) scores were calculated for each patient and stratified into four groups (RCRI 1, 2, 3, ⩾ 4). A Poisson regression model with robust standard errors of variance was employed to correlate the 90-day postoperative survival with each level of the Revised Cardiac Risk Index.RESULTS: A total of 24,198 patients met the study inclusion criteria. 90-day postoperative mortality increased from 2.4% in patients with RCRI 1 to 10.1% in patients with RCRI ⩾ 4 (p < 0.001). Adjusted 90-day postoperative mortality increased linearly with an increasing RCRI, where an RCRI of 2, 3, and ≥ 4 respectively led to a 46%, 80%, and 167% increased risk of mortality compared to RCRI 1 (p < 0.001).CONCLUSIONS: A strong association between an increasing Revised Cardiac Risk Index score and increased 90-day postoperative mortality risk was detected. The Revised Cardiac Risk Index may facilitate risk stratification of patients undergoing elective colon cancer surgery.
4.	Andersson, R., et al. (författare) Surgical Infections and Antibiotic Stewardship : In Need for New Directions 2021 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 110:1, s. 110-112 Tidskriftsartikel (refereegranskat)abstract Background and Aims: Patients undergoing surgery are prone to infections, either at the site of surgery (superficial or organ-space) or at remote sites (e.g. pneumonia or urinary tract). Surgical site infections are associated with substantial morbidity and mortality, increased length of hospital stay and represent a huge burden to the health economy across all healthcare systems. Here we discuss recent advances and challenges in the field of surgical site infections. Material and Methods: Review of pertinent English language literature. Results: Numerous guidelines and recommendations have been published in order to prevent surgical site infections. Compliance with these evidence-based guidelines vary and has not resulted in any major decrease in the surgical site infection rate. To date, most efforts to reduce surgical site infection have focused on the role of the surgeon, but a more comprehensive approach is necessary. Conclusion: Surgical site infections need to be addressed in a structured way, including checklists, audits, monitoring, and measurements. All stakeholders, including the medical profession, the society, and the patient, need to work together to reduce surgical site infections. Most surgical site infections are preventable—and we need a paradigm shift to tackle the problem.
5.	Andersson, R., et al. (författare) The Dilemma of Drains after Pancreatoduodenectomy : Still an Issue? 2020 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 109:4, s. 359-361 Tidskriftsartikel (refereegranskat)abstract Background and Aims: Routine drainage after pancreatoduodenectomy is a controversial issue. In this article, we present and discuss the current evidence on abdominal drains in pancreatic surgery. Material and Methods: Review of the pertinent English-language literature. Results: There is a growing body of evidence showing a lack of benefit of prophylactic drainage after pancreatoduodenectomy. Randomized trials have reported similar outcomes with or without routine drains. If drains were used, early removal was found to be superior to late removal in patients with a low risk of postoperative pancreatic fistula. Consequently, criteria for early drain removal have been developed based on the measurement of drain amylase levels. On the contrary, there exists a subgroup of patients where drains may have a role. In patients with high risk of pancreatic fistula formation, such as those having a soft pancreatic texture, small pancreatic duct and high body mass index, the placement of drains may give sentinel information about future clinical deterioration. The drain may thus help reduce failure-to-rescue rates. Conclusion: Despite much research, there are many unanswered questions regarding drains in pancreatic surgery. It is evident that routine drainage should be abandoned for a more selective strategy. Furthermore, what is needed is a postoperative warning score that early on can identify patients at risk of a pancreatic fistula, without the routine placement of drains.

(författare) Surgical resection of pancreatic cancer with synchronous hepatic oligometastases : Real benefit or selection bias? 2022 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 111:2 Tidskriftsartikel (refereegranskat)abstract In this editorial, we review the evidence for liver resection in patients with oligometastatic pancreatic cancer.
7.	Banys-Paluchowski, M, et al. (författare) Axillary staging in node-positive breast cancer converting to node negativity through neoadjuvant chemotherapy: Current evidence and perspectives 2023 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267. ; 112:2, s. 117-125 Tidskriftsartikel (refereegranskat)abstract Over the recent years, axillary staging of initially node-positive breast cancer patients converting to clinical node negativity after neoadjuvant chemotherapy has seen rapid changes. This narrative review aims to give a contemporary overview over published evidence and clinical practice, and thus provide some guidance to the surgical community in the process of re-evaluating and re-shaping surgical practice. Methods: The search strategy aimed at finding relevant studies. Only articles in English were considered. Results: The introduction of modern techniques offer more precise staging surgery and thus hopefully reduced arm morbidity. Clinical practice has however diverged both within countries and internationally. While some countries have adapted de-escalated axillary staging techniques such as targeted axillary dissection, targeted lymph node biopsy or sentinel lymph node biopsy, others continue to recommend a full axillary lymph node dissection. With the implementation of new techniques, many questions arise, regarding aspects of oncological safety, technical performance, budget and practicality, patient selection and indications for different levels of axillary staging procedures. Conclusions: There is a growing body of evidence on de-escalation of axillary surgery in the setting of cN+ → ycN0 breast cancer treated with neoadjuvant chemotherapy. However, standards differ between countries and future studies are necessary to fully assess the optimal strategy for these patients.

9.	Carlstedt, Anders, et al. (författare) Management of Diastasis of the Rectus Abdominis Muscles : Recommendations for Swedish National Guidelines 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 10:3, s. 452-459 Tidskriftsartikel (refereegranskat)abstract Background: Diastasis of the rectus abdominis muscle is a common condition. There are no generally accepted criteria for diagnosis or treatment of diastasis of the rectus abdominis muscle, which causes uncertainty for the patient and healthcare providers alike. Methods: The consensus document was created by a group of Swedish surgeons and based on a structured literature review and practical experience. Results: The proposed criteria for diagnosis and treatment of diastasis of the rectus abdominis muscle are as follows: (1) Diastasis diagnosed at clinical examination using a caliper or ruler for measurement. Diagnostic imaging by ultrasound or other imaging modality, should be performed when concurrent umbilical or epigastric hernia or other cause of the patient's symptoms cannot be excluded. (2) Physiotherapy is the firsthand treatment for diastasis of the rectus abdominis muscle. Surgery should only be considered in diastasis of the rectus abdominis muscle patients with functional impairment, and not until the patient has undergone a standardized 6-month abdominal core training program. (3) The largest width of the diastasis should be at least 5 cm before surgical treatment is considered. In case of pronounced abdominal bulging or concomitant ventral hernia, surgery may be considered in patients with a smaller diastasis. (4) When surgery is undertaken, at least 2 years should have elapsed since last childbirth and future pregnancy should not be planned. (5) Plication of the linea alba is the firsthand surgical technique. Other techniques may be used but have not been found superior. Discussion: The level of evidence behind these statements varies, but they are intended to lay down a standard strategy for treatment of diastasis of the rectus abdominis muscle and to enable uniformity of management.
10.	Chabok, Abbas, 1964-, et al. (författare) Changing Paradigms in the Management of Acute Uncomplicated Diverticulitis 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:2, s. 180-186 Forskningsöversikt (refereegranskat)abstract Left-sided colonic diverticulitis is a common condition with significant morbidity and health care costs in Western countries. Acute uncomplicated diverticulitis which is characterized by the absence of organ dysfunction, abscesses, fistula, or perforations accounts for around 80% of the cases. In the last decades, several traditional paradigms in the management of acute uncomplicated diverticulitis have been replaced by evidence-based routines. This review provides a comprehensive evidence-based and clinical-oriented overview of up-to-date diagnostics with computer tomography, non-antibiotic treatment, outpatient treatment, and surgical strategies as well as follow-up of patients with acute uncomplicated diverticulitis.
11.	Danielson, Johan, 1975-, et al. (författare) Percutaneous Hernia Repair in Children : Safe to introduce 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:3, s. 380-385 Tidskriftsartikel (refereegranskat)abstract Background and objective:In 2014 we introduced percutaneous internal ring suture as an alternative to open surgery for the treatment of inguinal hernia. This study aims to evaluate the introduction of the procedure at our institution.Methods:In total, 100 consecutive patients operated with percutaneous internal ring suture were compared with 100 consecutive patients operated with open surgery. The patients were operated from August 2014 until November 2017. Patient demographics, clinical history, operative time, time in theater, and postoperative complications were extracted from charts.Results:The mean operative time for percutaneous internal ring suture was 26.54 min and for open surgery 39.94 min, P < 0.0001. The total mean operative theater time for percutaneous internal ring suture was 108.95 min and for open surgery 118.4 min, P = 0.0343. During follow-up, two percutaneous internal ring sutures were operated for recurrent hernia. In the open surgery-group, three patients were operated for recurrent hernia, three for secondary testicular retention, and three for metachronous contralateral hernia.Conclusions:Even when established as a new technique, the percutaneous internal ring suture procedure is safe and results in shorter operative time and shorter theater time compared to open surgery.
12.	Davidson, Thomas, et al. (författare) Robot-assisted pelvic and renal surgery compared with laparoscopic or open surgery: Literature review of cost-effectiveness and clinical outcomes 2023 Ingår i: Scandinavian Journal of Surgery. - : SAGE PUBLICATIONS LTD. - 1457-4969 .- 1799-7267. Forskningsöversikt (refereegranskat)abstract Background and aim: The purpose of this study was to evaluate clinical experiences and cost-effectiveness by comparing robot-assisted surgery with laparoscopic- or open surgery for pelvic and renal operations. Methods: A narrative review was carried out. Results: When using robotic-assisted surgery, oncological and functional results are similar to after laparoscopic or open surgery. One exception may be a shorter survival in cancer of the cervix uteri. In addition, postoperative complications after robotic-assisted surgery are similar, bleeding and transfusion needs are less, and the hospital stay is shorter but the preparation of the operating theater before and after surgery and the operation times are longer. Finally, robot-assisted surgery has, in several studies, been reported to be not cost-effective primarily due to high investment costs. However, more recent studies provide improved cost-effectiveness estimates due to more effective preparation of the operating theater before surgery, improved surgeon experience, and decreased investment costs. Conclusions: Complications and functional and oncological outcomes after robot-assisted surgery are similar to open surgery and laparoscopic surgery. The cost-effectiveness of robot-assisted surgery is likely to equal or surpass the alternatives.
13.	Eriksson, John, et al. (författare) Primary small intestinal neuroendocrine tumors are highly prevalent and often multiple before metastatic disease develops 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:1, s. 44-50 Tidskriftsartikel (refereegranskat)abstract Background: Small intestinal neuroendocrine tumors are the most common of small bowel malignancies with a clinical incidence of about 1 per 100,000 persons per year. There has been a threefold increase in the incidence of small intestinal neuroendocrine tumor during later decades, but there are no studies that clarify whether this is due to a true higher incidence or if the rise is a mere product of, for instance, improved diagnostic modalities. The aim of this study was to investigate the incidence of clinical as well as subclinical small intestinal neuroendocrine tumors found at autopsy as well as describing the frequency of concomitant malignancies in patients with small intestinal neuroendocrine tumor. Materials and methods: An autopsy registry from the Malmo county population from 1970 to 1982 with an 87% autopsy rate was used. The clinical autopsy reports for patients coded for the existence of "carcinoid tumor" were scrutinized for the presence of small intestinal neuroendocrine tumor, metastatic disease, and concomitant malignancies. Details of patients with clinically diagnosed small intestinal neuroendocrine tumor during this time period were gathered from the Swedish Cancer Registry. Results: The mean annual incidence of small intestinal neuroendocrine tumor during this period was 5.33 per 100,000 individuals, and the mean annual prevalence was 581 per 100,000. The cause of death in the majority of cases was not due to small intestinal neuroendocrine tumor. In total, 48% of the people with small intestinal neuroendocrine tumor had at least one other malignancy, most commonly colorectal cancer. Conclusion: Most small intestinal neuroendocrine tumors are subclinical, and persons living with them will often die due to other causes. There was a high rate of multiple primary tumors (40%), suggesting that multiple tumors seem to arise before the advent of metastatic disease. Moreover, a comparably high rate of associated colorectal carcinoma was found.
14.	Fagevik Olsén, Monika, 1964, et al. (författare) Development of and adherence to an ERAS® and prehabilitation protocol for patients undergoing pancreatic surgery: An observational study 2023 Ingår i: Scandinavian Journal of Surgery. - 1457-4969 .- 1799-7267. ; 112:4, s. 235-245 Tidskriftsartikel (refereegranskat)abstract Background and objective: There are still gaps in knowledge concerning the adherence to different multimodal pathways in pancreatic surgery. The aim of this trial was to explore and evaluate an Enhanced Recovery After Surgery (ERAS®) and prehabilitation protocol in patients undergoing open pancreatic surgery. Methods: Three groups of patients were included: two prospective series of 75 patients undergoing open pancreatic surgery following an ERAS® protocol with or without prehabilitation, and one group of 55 historical controls. Variables regarding adherence to, and effects of the protocols, were collected from the local database and the patients’ hospital records. Patients’ adherence to advice given pre-operatively was followed up using a study-specific questionnaire. Results: The patients reported high adherence to remembered advice given. The health care professionals’ adherence to the various parts of the concepts varied. ERAS® implementation resulted in more frequent gut motility stimulation (p < 0.001) and shorter duration of epidural anesthesia, site drains, and urinary catheter (p = 0.001). With prehabilitation, more patients were screened concerning nutritional status and prescribed preoperative training (p < 001). There was a significant change in weight before surgery, a shorter time to first flatus and a shorter length of stay after implementation of the concepts (p < 0.05). Complications were rare in all three groups and there were no significant differences between the groups. Conclusion: The implementation of an ERAS® and a prehabilitation protocol increased adherence to the protocols by both patients and healthcare professionals. An implementation of an ERAS® protocol with and without prehabilitation decreases length of stay and may decrease preoperative weight loss and time to bowel movement.
15.	Fröberg, Klara, et al. (författare) Outcome after total pancreatectomy with islet autotransplantation : a European single-center study 2024 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 113:2, s. 80-87 Tidskriftsartikel (refereegranskat)abstract Background and aims: Chronic pancreatitis may cause intractable abdominal pain, with total pancreatectomy sometimes being the last resort. To mitigate the subsequent diabetes, total pancreatectomy can be followed by islet autotransplantation (TP-IAT). The primary aim of this study was to assess the outcomes in patients undergoing TP-IAT at Karolinska University Hospital with respect to safety, postoperative complications, and islet graft function. A secondary aim was to compare liver to skeletal muscle as autotransplantation sites.Methods: Single-center observational cohort study on patients undergoing TP-IAT. Islets were transplanted either into the liver or skeletal muscle. Data on baseline characteristics and pretransplantory conditions were collected. Outcome measures included mortality and major postoperative complications as well as the glycemic measures: insulin use, fasting C-peptide, and HbA1c.Results: Between 2004 and 2020, 24 patients underwent TP-IAT. Islets were transplanted into the liver in 9 patients and into skeletal muscle in 15 patients. There was no 90-day mortality, and major complications (Clavien–Dindo ⩾IIIa) occurred in 26.7%, all related to the procedure of total pancreatectomy. Fasting C-peptide could be detected postoperatively, with higher levels in patients receiving islet autotransplantation into the liver (p = 0.006). Insulin independence was not achieved, although insulin doses at last follow-up were significantly lower in patients receiving islet autotransplantation into the liver compared to skeletal muscle (p = 0.036).Conclusion: TP-IAT is safe and associated with tolerable risk, the component of islet autotransplantation being seemingly harmless. Although islet grafts maintain some endocrine function, insulin independence should not be expected. Regarding islet autotransplantation sites, the liver seems superior to skeletal muscle. Clinical trial registration: Not applicable.
16.	Gilg, Stefan, et al. (författare) Molecular adsorbent recirculating system treatment in patients with post-hepatectomy liver failure : Long-term results of a pilot study 2022 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 111:3, s. 48-55 Tidskriftsartikel (refereegranskat)abstract Background: Post-hepatectomy liver failure (PHLF) is the leading cause of postoperative mortality following major liver resection. Between December 2012 and May 2015, 10 consecutive patients with PHLF (according to the Balzan criteria) following major/extended hepatectomy were included in a prospective treatment study with the molecular adsorbent recirculating system (MARS). Sixty- and 90-day mortality rates were 0% and 10%, respectively. Of the nine survivors, four still had liver dysfunction at 90 days postoperatively. One-year overall survival (OS) of the MARS-PHLF cohort was 50%. The present study aims to assess long-term outcome of this cohort compared to a historical control cohort.Methods: To compare long-term outcome of the MARS-PHLF treatment cohort with PHLF patients not treated with MARS, the present study includes all 655 patients who underwent major hepatectomy at Karolinska University Hospital between 2010 and 2018. Patients with PHLF were identified according to the Balzan criteria.Results: The cohort was split into three time periods: pre-MARS period (n = 192), MARS study period (n = 207), and post-MARS period (n = 256). The 90-day mortality of patients with PHLF was 55% (6/11) in the pre-MARS period, 14% during the MARS study period (2/14), and 50% (3/6) in the post-MARS period (p = 0.084). Median OS (95% confidence interval (CI)) was 37.8 months (29.3–51.7) in the pre-MARS cohort, 57 months (40.7–75.6) in the MARS cohort, and 38.8 months (31.4–51.2) in the post-MARS cohort. The 5-year OS of 10 patients included in the MARS study was 40% and the median survival 11.6 months (95% CI: 3 to not releasable). In contrast, for the remaining 21 patients fulfilling the Balzan criteria during the study period but not treated with MARS, the 5-year OS and median survival were 9.5% and 7.3 months (95% CI, 0.5–25.9), respectively (p = 0.138)).Conclusions: MARS treatment may contribute to improved outcome of patients with PHLF. Further studies are needed.The initial pilot study was registered at ClinicalTrials.gov (NCT03011424).
17.	Gustafsson, Arvid, et al. (författare) Bile leakage and the number of metal clips on the cystic duct during laparoscopic cholecystectomy 2022 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 111:2, s. 1-8 Tidskriftsartikel (refereegranskat)abstract BACKGROUND AND OBJECTIVE: The most common way of closing the cystic duct in laparoscopic cholecystectomy is by using metal clips (>80%). Nevertheless, bile leakage occurs in 0.4%-2.0% of cases, and thus causes significant morbidity. However, the optimal number of clips needed to avoid bile leakage has not been determined. The primary aim of this study was to evaluate bile leakage and post-procedural adverse events after laparoscopic cholecystectomy concerning whether two or three clips were used to seal the cystic duct.METHODS: Using a retrospective observational design, we gathered data from the Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (ERCP) (GallRiks). From 2006 until 2019, 124,818 patients were eligible for inclusion. These were nested to cohorts of 75,322 (60.3%) for uncomplicated gallstone disease and 49,496 (39.7%) with complicated gallstone disease. The cohorts were grouped by the number (i.e. two or three) of metal clips applied to the proximal cystic duct. The main outcome was 30-day bile leakage and post-procedural adverse events.RESULTS: No significant differences surfaced in the rate of bile leakage (0.8% vs 0.8%; P = .87) or post-procedural adverse events (three clips, 5.7% vs two clips, 5.4%; P = .16) for uncomplicated gallstone disease. However, for complicated disease, bile leakage (1.4% vs 1.0%; P < .001) and post-procedural adverse events (10.2% vs 8.6%; P < .001) significantly increased when the cystic duct was sealed with three clips compared with two.CONCLUSIONS: Because no differences in the rates of bile leakage or adverse events emerged in uncomplicated gallstone disease when a third clip was applied, a third clip for additional safety is not recommended in such cases. On the contrary, bile leakage and adverse events increased when a third clip was used in patients with complicated gallstone disease. This finding probably indicates a more difficult cholecystectomy rather than being caused by the third clip itself.
18.	Heiman, Jenny, 1980, et al. (författare) The effect of nonsupervised physical activity before and after breast cancer surgery on quality of life: Results from a randomized controlled trial (PhysSURG-B) 2022 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 111:4 Tidskriftsartikel (refereegranskat)abstract Background and objective: The PhysSURG-B trial of prehabilitation before breast cancer surgery randomized patients to a nonsupervised physical activity or a control group. The effects of the intervention on short- and long-term quality of life (QoL) were examined, with a subgroup analysis of patients receiving adjuvant chemotherapy. Methods: Female patients planned for surgery were randomly assigned to either an intervention of 30 min of self-administered physical aerobic activity daily 2 weeks before and 4 weeks after surgery or control. QoL was assessed with questionnaires at baseline, 4 weeks and 12 months postoperatively using the instruments FACT-B, RAND-36, and EQ-VAS. Results: Of 354 included participants at 12 months after surgery, 287 were available for analysis. FACT- B scores at 4 weeks and 12 months showed no differences between intervention compared to control, odds ratio (OR) of 0.975 (95% confidence interval (CI) 0.636-1.495) and 0.883 (95% CI 0.581-1.342), respectively. There was no difference in EQ-VAS comparing intervention to control at 4 weeks and 12 months, respectively, OR 1.163 (95% CI 0.760-1.779) and 0.817 (95% CI 0.559-1.300). RAND-36 domains "role limitations due to physical health" and "pain" showed a decrease at 4 weeks in both groups, returning toward baseline at 12 months follow-up. The subgroup who received adjuvant chemotherapy had significantly lower QoL measured using FACT-B at 12 months compared to patients not receiving chemotherapy (OR 0.475; 95% CI 0.300-0.753). Conclusions: An intervention of non-supervised physical activity before and after surgery for breast cancer showed no effect on short or long-term QoL, compared to control.

(författare) Management of groin hernia repair in Sweden : a register-based comparative analysis of public and private healthcare providers 2024 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. Tidskriftsartikel (refereegranskat)abstract Background: Swedish healthcare is in a period of transition with an expanding private sector. This study compares quality of outcome after groin hernia repair performed in a public or private healthcare setting.Methods: A cohort study based on data from the Swedish National Hernia Register combined with Patient-Reported Outcome Measures (PROMs) 1 year after groin hernia repair. Between September 2012 and December 2018, a questionnaire was sent to all patients registered in the hernia register 1 year after surgery. Endpoints were reoperation for recurrence, chronic pain, and patient satisfaction.Results: From a total of 87,650 patients with unilateral groin hernia repair, 61,337 PROM answers (70%) were received from 71 public and 28 private healthcare providers. More females, acute and recurrent cases, and patients with high American Society of Anesthesiology (ASA) scores were operated under the national healthcare system. The private sector had more experience surgeons with higher annual volume per surgeon, shorter time on waiting lists, and shorter operation times. No difference was seen in patient satisfaction. Groin hernia repair performed in a private clinic was associated with less postoperative chronic pain (OR 0.85, 95% CI 0.8–0.91) but a higher recurrence rate (HR 1.41; 95% CI 1.26–1.59) in a multivariable logistic regression analysis.Conclusion: Despite private clinics having a higher proportion of experienced surgeons and fewer complex cases, the recurrence rate was higher, whereas the risk for chronic postoperative pain was higher among patients treated in the public sector.

(författare) Patient-reported Outcome in Surgically Treated Pelvic Ring Injuries at 5 Years Post-surgery 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:1, s. 86-92 Tidskriftsartikel (refereegranskat)abstract BACKGROUND AND AIMS: Long-term prospective data on patient-reported outcome after surgical treatment of pelvic ring injuries are scarce. This study aimed at describing results at 5 years post-surgery using validated outcome measures.PATIENTS AND METHODS: Patients admitted for surgical treatment of pelvic ring injuries were prospectively included and asked to report their outcome at 1, 2 and 5 years post-surgery using two patient-reported outcome measures: the generic Short-Form 36 and the condition-specific pelvic discomfort index. Data were evaluated using mixed-effects linear models.RESULTS: There were 108 patients (68 males and 40 females), mean age 38 years. Injury type according to the AO/OTA-classification was B-type in 68 patients and C-type in 40 patients. No domain of the Short-Form 36 reached norm values at 5 years post-surgery. Females reported a worse outcome than males concerning general health (p < 0.01) at 5 years. Recovery of physical function (p < 0.01), mental health (p = 0.04), and pain (p = 0.01) was observed for males at 5 years compared to earlier assessments, while females on the contrary described more pain at this time-point (p = 0.03). Mean pelvic discomfort index at 5 years was 27, indicating moderate residual pelvic discomfort overall. Males reported less pelvic discomfort than females at 5 years (p = 0.02) and improved when compared to results at 2 years (p = 0.02), while females did not. Influence of age, fracture type, and presence of associated injuries on patient-reported outcome was limited.CONCLUSION: Surgically treated pelvic ring injuries are associated with long-standing negative effects on patient-reported outcome. Males report a better outcome than females at 5 years post-surgery.
21.	Johansen, N., et al. (författare) Surgical Strategy for Contralateral Groin Management in Patients Scheduled for Unilateral Inguinal Hernia Repair : An International Web-Based Surveymonkey® Questionnaire: Strategy for Contralateral Groin Management during Inguinal Hernia Repair 2021 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 110:3, s. 368-372 Tidskriftsartikel (refereegranskat)abstract Background: A contralateral occult inguinal hernia is frequently observed in patients planned for a unilateral laparoscopic inguinal hernia repair. Surgical strategy for contralateral groin management in patients scheduled for an endo-laparoscopic unilateral inguinal hernia repair is controversial and based on questionable evidence. This study aimed to gather international opinion concerning the surgical strategy for the contralateral asymptomatic side when no hernia or lipoma is clinically evident at the preoperative examination or anamnesis. Methods: An international Internet-based questionnaire was sent to all the members of the European Hernia Society, the Americas Hernia Society, and the Asia Pacific Hernia Society. The clinical scenario for responders was a patient with a unilateral symptomatic inguinal hernia planned for endo-laparoscopic repair with no preoperative symptoms/lump on the contralateral side. Results: A total of 640 surgeons replied (response rate = 26%), of whom 506 were included for analysis. Most surgeons had performed > 300 repairs. The preferred surgical technique was evenly distributed between laparoscopic total extraperitoneal repair and laparoscopic transabdominal preperitoneal repair. In total, 54% preferred to implant a prophylactic mesh on the contralateral side when an occult hernia was found, 47% when a lipoma was found, and 6% when no occult hernia/lipoma was identified. Conclusion: Mesh implementation was preferred by half of the endo-laparoscopic hernia surgeons for a contralateral occult hernia and/or lipoma. Although not supported by strong evidence, mesh implantation on the asymptomatic contralateral side might be cost-effective and perhaps beneficial in the long term but could be offset by increased risk of chronic pain and sexual dysfunction.

(författare) Does 18F-FDG PET/CT change the surgical management of potentially resectable colorectal liver metastases? 2022 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 111:1 Tidskriftsartikel (refereegranskat)abstract PURPOSE: Resectability assessment of patients with colorectal liver metastases is based on computed tomography and liver magnetic resonance imaging. Addition of fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography has been recommended, but the impact of the added information remains unclear. The primary aim of this study was to determine how preoperative positron emission tomography/computed tomography changed management in patients with potentially resectable colorectal liver metastases. The secondary aim was to investigate whether findings on positron emission tomography/computed tomography correlated to metastatic disease in cases with extended surgery and influenced oncological outcomes. METHODS: A retrospective observational study of the impact of adding positron emission tomography/computed tomography to conventional imaging in the surgical decision-making of colorectal liver metastases. All patients with colorectal liver metastases diagnosed by conventional imaging were included and assessed by a multidisciplinary team conference at Umeå University Hospital between June 2013 and December 2017. Eligibility criteria were all patients with potentially resectable colorectal liver metastases. Patients who underwent preoperative positron emission tomography/computed tomography in addition to conventional radiology were compared with those who underwent conventional imaging only. RESULTS: 151/220 patients underwent preoperative positron emission tomography/computed tomography. Findings on positron emission tomography/computed tomography changed the management in 10.6% of the patients. Eight patients were excluded from surgery after detection by positron emission tomography/computed tomography of extrahepatic disease. Eight patients underwent more extended surgery than initially planned due to positron emission tomography/computed tomography. Five of these positron emission tomography-positive resected sites were verified by pathology as metastatic disease. No difference in overall survival was seen following surgical resection in patients with and without a preoperative positron emission tomography/computed tomography. CONCLUSIONS: Preoperative positron emission tomography/computed tomography resulted in a changed surgical management in 10.6% of cases in a selected cohort.

Juhlin, CC (författare) A Clinical Overview of Telomerase-Associated Aberrancies in Follicular Thyroid Tumors as Diagnostic and Prognostic Markers: Tert Alert! 2020 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267. ; 109:3, s. 187-192 Tidskriftsartikel (refereegranskat)abstract Endocrine surgeons and pathologists alike are well aware of the diagnostic predicament that follicular thyroid tumors impose in the clinical setting, best exemplified by the current inability to preoperatively assess the malignant potential of each individual lesion. As the proper recognition of a follicular thyroid carcinoma lies in the histopathological identification of invasive behavior, preoperative cytology alone is not yet sufficient to identify malignant tumors eligible for a total thyroidectomy upfront. Numerous auxiliary markers have been proposed as discriminating markers between follicular thyroid carcinomas and follicular thyroid adenomas, although many have proven suboptimal in terms of sensitivity, specificity, or overall clinical practicality. Of late, recurrent promoter mutations in the telomerase reverse transcriptase gene have been intimately coupled to subsets of well-differentiated thyroid cancer specimen with aggressive clinical characteristics as well as less differentiated forms of thyroid cancer with exceedingly poor prognosis. The mutations are thought to enhance the telomerase reverse transcriptase gene expressional output and cause immortalization through telomerase-associated mechanisms. Materials and Methods: In this review, the current value of telomerase reverse transcriptase promoter mutations is detailed from a clinical angle—as well as the possible future application of additional telomerase reverse transcriptase gene aberrations as adjunct markers for the proper recognition of malignant potential. Results: Telomerase reverse transcriptase promoter mutations are found in subsets of follicular thyroid carcinomas and follicular tumors of uncertain malignant potential while exceedingly rare in recurrence-free follicular thyroid adenomas. Collectively, these aberrancies are suggested as possible diagnostic and prognostic discriminators of follicular thyroid tumors. Conclusions: Telomerase reverse transcriptase gene analyses greatly facilitate the clinical assessment of follicular thyroid tumors, and pinpoints cases at risk of future recurrences. High-volume, tertiary thyroid centers are therefore recommended to implement the mutational screening in clinical routine.

(författare) Computed Tomography Verified Prevalence of Incisional Hernia 1 Year Postoperatively after Colorectal Cancer Resection 2021 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1799-7267 .- 1457-4969. ; 110:3, s. 373-379 Tidskriftsartikel (refereegranskat)abstract BACKGROUND AND OBJECTIVE: Incisional hernia is a frequent negative outcome after open and minimal invasive surgery of colorectal cancer. This study aimed to determine computed tomography-verified incisional hernia prevalence 1-year post colorectal cancer surgical resection in patients sutured with standardized small stich 4:1 technique, identify risk factors for incisional hernia and assess to what extent incisional hernia required surgical correction.METHODS: All patients subjected to resectional colorectal cancer surgery during 2012-2016 at Skåne University Hospital were identified in the Swedish Colorectal Cancer Registry. The 1-year follow-up computed tomography was re-evaluated to establish the presence of incisional hernia. Clinical data were collected from Swedish Colorectal Cancer Registry and the patients' medical charts were reviewed. Non-parametric tests and binary logistic regression analysis were used for statistical analysis.RESULTS: In total, 1744 tumors were identified resulting in 1231 patients meeting the inclusion criteria. In total, 25.9% (n = 319) had incisional hernia at the 1-year follow-up computed tomography and 13.2% (n = 162) of the colorectal cancer resections were minimal invasive surgery, and there was non-significant incisional hernia prevalence difference between open and minimal invasive surgery. However, for converted and non-converted minimal invasive surgery, the incisional hernia frequencies were 43.9% (n = 18) and 24.1% (n = 39), respectively (p = 0.012). Significant risk factors for incisional hernia were body mass index, wound rupture, and procedure time. During the follow-up time, 14.1% (n = 45) needed incisional hernia corrective surgery.CONCLUSIONS: Incisional hernia after colorectal cancer surgery is common despite standardized small stich 4:1 closure, but few incisional hernias are surgically corrected. Incisional hernia is equally frequent after open surgery and minimal invasive surgery. However, the risk of incisional hernia is considerably higher after minimal invasive surgery conversion.

Materials and Methods: Three hundred and sixty-two children with an upper limb defect, born 1993–2005, and alive after birth admission were identified in the Finnish Register of Congenital Malformations. The data on hospital care, with focus on operative treatment, were collected from the National Hospital Discharge Register, until 31 December 2009. Mean follow-up was 10.2 years (range: 4–17 years). The results were compared with data on the whole children population (1.1 million) in Finland. Results: Most children (321, 87%) with upper limb defects had hospital admissions: on average, one admission/year (range: 0–36), and they were treated in hospital 5 days/year (range: 0–150), which is 11-fold compared with an average child in Finland. Four surgical procedures/child were done (range: 0–45), including one hand surgical procedure. The most common procedures were orthopedic (513); gastrointestinal (263); ear, nose, and throat (143); dental (118); thoracic (48); and urologic (44). Of the 513 orthopedic procedures, 326 were directed to upper limbs, 107 to the lower limbs, and 10 to the spine. Median operation age was 2 years 7 months. Altogether, 60% of hospital admissions were non-surgical. Leading causes of non-operative hospital admissions were congenital anomalies (32%), gastroenterological problems (20%), respiratory tract conditions (13%), neurological problems (7%), perinatal conditions (5%), and infectious diseases (5%). Conclusion: Treatment of children with upper limb defects is teamwork between pediatric and surgical subspecialties. Burden of hospital care is 11-fold as compared with an average child.

(författare) In the Era of the Leeds Protocol: A Systematic Review and A Meta-Analysis on the Effect of Resection Margins on Survival Among Pancreatic Ductal Adenocarcinoma Patients 2020 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267. ; 109:1, s. 11-17 Tidskriftsartikel (refereegranskat)abstract A positive resection margin is considered to be a factor associated with poor prognosis after pancreatic ductal adenocarcinoma resection. However, analysis of the resection margin is dependent on the pathological slicing technique. The aim of this systematic review and meta-analysis was to study the impact of resection margin on the survival of pancreatic ductal adenocarcinoma patients whose specimens were analyzed using the axial slicing technique. Material and Methods: A systematic search in the PubMed, Cochrane, and Embase datasets covering the time period from November 2006 to January 2019 was performed. Only studies with axial slicing technique (Leeds Pathology Protocol or Royal College of Pathology Protocol) were included in the final database. Meta-analysis between the marginal distance and survival was performed with the Inverse Variance Method in RevMan. Results: The systematic search resulted in nine studies meeting the inclusion criteria. The median survival for a resection margin 0 mm ranged from 12.3 to 23.4 months, for resection margin <0.5 mm 16 months, for resection margin <1 mm ranged from 11 to 27.5 months, for resection margin <1.5 mm ranged from 16.9 to 21.2 months, and for resection margin >2 mm ranged from 53.9 to 63.1 months. Five studies were eligible for meta-analysis. The pooled multivariable hazard ratio favored resection margin ⩾1 mm (hazard ratio: 1.32 and 95% confidence interval: 1.03–1.68, p = 0.03). Conclusion: Resection margins ⩾1 mm seem to lead to better survival in pancreatic ductal adenocarcinoma patients than resection margin <1 mm. However, there is not enough data to evaluate the effect of oncologic therapy or to analyze the impact of other resection margin distances on survival.

(författare) Safe Introduction of Minimally Invasive Esophagectomy at a Medium Volume Center 2020 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 109:2, s. 121-126 Tidskriftsartikel (refereegranskat)abstract Background and Aims: Minimally invasive esophagectomy is a favored alternative in high-volume centers. We evaluated the introduction of, and transition to, minimally invasive esophagectomy at a medium volume tertiary referral center (10-20 esophagectomies annually) with focus on surgical results. Material and Methods: Patients who underwent minimally invasive esophagectomy or open transthoracic surgery for carcinoma of the esophagus or gastroesophageal junction (Siewert I and II) during 2007-2016 were retrospectively studied. Sorted on surgical approach, perioperative data, surgical outcomes, and postoperative complications were analyzed and multivariate regression models were used to adjust for possible confounders. Results: One hundred and sixteen patients were included, 51 minimally invasive esophagectomy (21 hybrid and 30 totally minimally invasive) and 65 open resections. The groups were well matched. However, higher body mass index, neoadjuvant chemoradiotherapy, and cervical anastomosis were more frequent in the minimally invasive esophagectomy group. Minimally invasive esophagectomy was associated with less peroperative bleeding (384 vs 607 mL, p = 0.036) and reduced length of stay (14 vs 15 days, p = 0.042). Duration of surgery, radical resection rate, and postoperative complications did not differ between groups. Lymph node yield was higher in the minimally invasive esophagectomy group, 18 (13-23) vs 12 (8-16), p < 0.001, confirmed in a multivariate regression model (adjusted odds ratio 3.15, 95% class interval 1.11-8.98, p = 0.032). Conclusion: The introduction of minimally invasive esophagectomy at a medium volume tertiary referral center resulted in superior lymph node yield, less peroperative blood loss and shorter length of stay, without compromising the rate of radical resection, or increasing the complication rate.

(författare) Regional variations in the treatment of gallstone disease may affect patient outcome : A large, population-based register study in sweden 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:3, s. 335-343 Tidskriftsartikel (refereegranskat)abstract Background: The lack of studies showing benefit from surgery in patients with symptoms of gallstone disease has led to a divergence in local practices and standards of care. This study aimed to explore regional differences in management and complications in Sweden. Furthermore, to study whether population density had an impact on management.Methods: Data were collected from the Swedish National Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks). Cholecystectomies undertaken for gallstone disease between January 2006 and December 2017 were included. Age, sex, American Society of Anesthesiologists (ASA) classification, intra- and post-operative complications, and the proportion of patients with acute cholecystitis who underwent surgery within 2 days of hospital admission were analyzed. The 21 different geographical regions in Sweden were compared, and each variable was analyzed according to population density.Results: A total of 139,444 cholecystectomies cases were included in this study. There were large differences between regions regarding indications for surgery and intra- and post-operative complications. In the analyses, there were greater divergences than would be expected by chance for most of the variables analyzed. Age of the cholecystectomized patients correlated with population density of the regions (R2 = 0.310; p = 0.0088).Conclusion: There are major differences between the different regions in Sweden in terms of the treatment of gallstone disease and outcome, but these did not correlate to population density, suggesting that local routines are more likely to have an impact on treatment strategies rather than demographic factors. These differences need further investigation to reveal the underlying causes.

One severe complication is the risk for blow-out of the remaining rectal remnant. The aim of this study was to compare the frequency and severity of complications in patients with the rectal remnant left subcutaneously versus patients with the rectal remnant left intra-abdominally. A secondary aim was to identify risk factors for complications. Materials and Methods: Consecutive patients at two tertiary centers in Sweden were retrospectively reviewed regarding surgical procedures; complications classified according to Clavien–Dindo; and possible risk factors for complications such as preoperative medication, emergency surgery, and body mass index. Results: 307 patients were identified. Minor complications were more common than previously reported (85%–89%). Severe surgical complications were not related to the handling of the rectal remnant. Leaving the rectal remnant subcutaneously was associated with local wound problems. Risk factors for severe complications were emergency surgery and preoperative medication with 5-aminosalicylic acid. Conclusion: Minor complications after colectomy for ulcerative colitis are very common and need to be addressed. Leaving the rectal stump intra-abdominally seems safe and may be advantageous to reduce local wound morbidity. © The Finnish Surgical Society 2019.
30.	Maghami, S., et al. (författare) Beta-blocker Therapy is Associated with Decreased 1-year Mortality After Emergency Laparotomy in Geriatric Patients 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:1, s. 37-43 Tidskriftsartikel (refereegranskat)abstract Background and Aims: Emergency laparotomy is associated with a great risk of mortality in the elderly. The hyperadrenergic state induced by surgical trauma may play an important role in the pathophysiology of this increased risk. Studies have shown that beta-blocker exposure may be associated with decreased morbidity and mortality in the perioperative period. We aimed to study the effect of beta-blocker on mortality in geriatric patients undergoing emergency laparotomy.Material and Methods: This is a retrospective study of patients who underwent emergency laparotomy between 1 January 2015 and 31 December 2016 at a single institution. The outcomes of interest were the association between post-operative complications and in-hospital and 1-year mortality in patients on beta-blocker therapy (BB(+)) and those who were not (BB(-)). The Poisson regression analysis was used to evaluate the association.Results: A total of 192 patients were included of whom 62 (32.2%) had pre-operative beta-blocker therapy with continued exposure during their hospital stay. The in-hospital mortality was 17.7% in the BB(+) and 23.8% in the BB(-) cohorts (p = 0.441). One-year mortality was significantly lower in the BB(+) group compared to the BB(-) group (30.6% versus 47.7%; p = 0.038). After adjusting for confounders, the incidence of deaths during 1 year post-operatively decreased by 35% in the BB(+) group (incidence rate ratio = 0.65, p = 0.004). No significant differences in the incidence of post-operative complications between the two groups could be measured.Conclusion: Beta-blocker therapy may be associated with reduced 1-year mortality following emergency laparotomy in geriatric patients.

Methods: The Cochrane Library, Embase, PubMed (MEDLINE), Web of Science and Scopus databases were systematically searched. The primary endpoint was parastomal hernia incidence. The secondary endpoint was incisional hernia incidence. Results: Five studies (four randomized controlled trials and one retrospective cohort) with a total of 699 patients were eligible for inclusion. The PSH rate was 15%–46% for Hartmann procedure, 0%–85% for primary anastomosis, 4% for resection, and 2% for laparoscopic lavage. The IH rates were 5%–38% for Hartmann procedure, 5%–27% for primary anastomosis, 9%–12% for primary resection, and 3%–11% for laparoscopic lavage. Conclusions: Both the parastomal and incisional hernia incidences are poorly evaluated and reported, and varied greatly between the studies.

(författare) Preoperatively suspected gallbladder cancer improves survival compared with incidental gallbladder cancer in pT3 patients 2024 Ingår i: Scandinavian Journal of Surgery. - : SAGE PUBLICATIONS LTD. - 1457-4969 .- 1799-7267. Tidskriftsartikel (refereegranskat)abstract Background: The aim was to compare survival for incidental gallbladder cancer (IGBC), respectively, preoperatively suspected gallbladder cancer (GBC), subjected to surgery for different pathological tumour (pT) stages and in different treatment groups in a national cohort. Methods: Data were collected and crosslinked from two national quality registers, SweLiv (2009-2019) and GallRiks (2009-2016). Survival was estimated using Kaplan-Meier analysis. The log-rank test and Cox regression analyses were used to compare groups. Results: In total, 466 IGBC patients, including 225 who only underwent simple cholecystectomy (SC), and 477 GBC patients were included. Most patients were female, with small differences in mean age between groups. In all IGBC patients compared with GBC patients, an improved 5-year overall survival in pT3 GBC undergoing surgery (GBC 13% vs all IGBC 8%, p < 0.001), was seen. GBC was shown to be an independent predictor for improved survival in pT3 patients (hazard ratio (HR): 0.6; 95% confidence interval (CI): 0.4-0.8, p < 0.001). In addition, in GBC with curative reresection compared with IGBC SC and IGBC with curative resection, an improved 5-year overall survival in pT3 GBC was shown (GBC 20% vs all IGBC 10%, p < 0.001). GBC was an independent predictor for improved survival in pT3 patients with curative resection (HR: 0.4; 95% CI: 0.3-0.7, p < 0.001). Conclusions: GBC was shown to be an independent predictor for improved survival in pT3 patients, and patients with GBC may benefit from one-stage resection. It is, therefore, reasonable to recommend that radiological suspicion of malignancy should be evaluated at a liver tumour centre to optimize patient outcomes.

A registry-based approach offers a possibility to investigate the factors affecting increased morbidity and early mortality, that is, death within 6 months of treatment. Methods: A retrospective registry review was conducted on a series of 317 consecutive microvascular free tissue transfers in head and neck cancer patients performed during 2013–2017 at the Helsinki University Hospital (Helsinki, Finland). All surviving patients had a minimum follow-up of 2 years (range 24–84 months). Results: Overall, 36 (11.4%) early deaths occurred in this series. In multivariable logistic regression analysis, patients aged 75 years and older ( p = 0.019), Adult Comorbidity Evaluation-27 (ACE-27) score of 3 ( p = 0.048), tumor class T3 ( p = 0.005), lymph node class N2 ( p = 0.014), or thrombocyte count of 360 (× 109 L) or more ( p = 0.001) were more likely to die within 6 months of surgery. Of these 36 patients, 27 (75%) had a complication warranting hospital care and most ( n = 22, 61%) had several complications. Conclusions: Early postoperative mortality most frequently affects patients aged 75 years and above, with a high ACE-27 score, advanced tumor stage, or high thrombocyte count. Therefore, preoperative assessment and patient selection should have a crucial role in this patient population.

(författare) Impact of parastomal hernia on colostomy costs at 1 year: Secondary analysis of a randomized clinical trial (STOMAMESH) 2024 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 113:1, s. 33-39 Tidskriftsartikel (refereegranskat)abstract Background and aims: Parastomal hernia (PSH) is a common complication after the creation of a colostomy, with a prevalence of approximately 50%. Despite the high frequency, little is known how PSH affects the cost of colostomy care. The hypothesis in this study was that PSH increases the cost of colostomy care compared with not having a PSH.Methods: Two groups with (N = 61) and without (n = 147) PSH were compared regarding costs of stoma appliances and visits. The population from a large randomized trial comparing construction of colostomy with or without prophylactic mesh (STOMAMESH) was used and cross-matched with health economic data from the National Pharmaceutical Register, 1 year after initial surgery.Results: Patients with and without a PSH were similar in basic demographic data. No difference in cost of stoma appliances (with PSH 2668.3 EUR versus no PSH 2724.5 EUR, p = 0.938) or number of visits to a stoma therapist (p = 0.987) was seen, regardless of the presence or not of a PSH.Conclusions: PSH appears not to affect costs due to colostomy appliances or the need to visit a stoma therapist, in the first year. The lesson to be learnt is that PSHs are not a driver for costs. Other factors may be determinants of the cost of a colostomy, including manufacturers' price and persuasion, means of procurement, and presence of guidelines.

(författare) Parastomal hernia repair; seldom performed and seldom reported : Results from a nationwide survey 2020 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 109:2, s. 96-101 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Parastomal hernia is common, but there are few population-based studies showing the frequency and outcome of parastomal hernia repair in routine surgical practice. The aim of this study was to identify patients undergoing surgery for parastomal hernia in Sweden and to define risk factors for complication and recurrence.METHODS: A broad search of the Swedish National Patient Register 1998-2007 for all possible parastomal hernia repairs using surgical procedure codes. Records of all patients identified were reviewed and those with a definite parastomal hernia procedure were included and analyzed.RESULTS: A total of 71 patients were identified after review of the records. The most common reason for surgery was cosmetic and the most frequent method was relocation of the stoma. Parastomal hernia recurrence rate was 18% during follow-up of a minimum 2 years. Overall, a surgical complication occurred in 32%. Possible risk factors were analyzed including emergency surgery versus planned, gender, age, indication for surgery, and method of surgery; none of which was significant.CONCLUSION: The frequency of parastomal hernia procedures was much lower than suggested by previous studies. The number of procedures per surgeon was even lower than expected. No specific risk factor could be identified. Parastomal hernia auditing in the form of a nationwide quality register should be mandatory. Centralization should be considered.

(författare) A single parathyroid hormone measurement two hours after a thyroidectomy reliably predicts permanent hypoparathyroidism 2021 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267. ; 110:3, s. 322-328 Tidskriftsartikel (refereegranskat)abstract Hypoparathyroidism is the most common complication following thyroidectomy, and various algorithms for early detection have been suggested. The aim of this study was to evaluate the predictive value of measuring the parathyroid hormone level 2 h after thyroidectomy and whether determination of the perioperative decline in parathyroid hormone added diagnostic value. Methods: Patients subjected to thyroidectomy for benign thyroid disorders were analyzed in (1) a retrospective register-based study (366 consecutive patients treated during 2015–2016) and (2) a prospective observational study (39 patients treated during 2018). Optimal cut-off values for postoperative parathyroid hormone and perioperative decline (%) in parathyroid hormone were determined by receiver operating characteristics and area under the curve. Sensitivity, specificity, positive and negative predictive values were calculated using cross tabulation. Results: The prevalence of hypoparathyroidism the first day after thyroidectomy was higher among patients treated for hyperthyroidism (30% vs 20%; P = 0.03). The optimal cut-off level for postoperative parathyroid hormone was 1.1 pmol/L (area under the curve = 0.887, 95% confidence interval: 0.839–0.934; positive predictive value: 88%, negative predictive value: 93%) for the entire cohort. When the groups were analyzed separately, the optimal cut-off was 1.05 for the non-hyperfunctioning group and 1.55 pmol/L for the group with hyperthyroidism. Twelve months after thyroidectomy, 3% were defined as having permanent hypoparathyroidism. Measurement of parathyroid hormone decline added diagnostic value for one patient with preoperative parathyroid-hormone-elevation associated with vitamin D deficiency. Conclusions: For patients with vitamin D sufficiency, the diagnostic accuracy of a single measurement of parathyroid hormone 2 h after thyroidectomy is an excellent indicator for predicting transient hypoparathyroidism.

(författare) Modified Peritoneal Flap Hernioplasty Versus Retromuscular Technique for Incisional Hernia Repair : a Retrospective Cohort Study 2020 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 109:4, s. 279-288 Tidskriftsartikel (refereegranskat)abstract Background and Aims: We present an open retromuscular mesh technique for incisional hernia repair, the modified peritoneal flap hernioplasty, where the fascia is sutured to the mesh and the hernia sac utilized for anterior mesh coverage. The aim was to describe the modified peritoneal flap hernioplasty technique and to compare it to a retromuscular repair, without component separation, regarding short-term complications, patient satisfaction, abdominal wall complaints, and recurrent incisional hernia. Materials and Methods: Consecutive patients operated electively with modified peritoneal flap hernioplasty technique (December 2012–December 2015) or retromuscular technique (Jan 2011–Oct 2014) were included in a retrospective single-center cohort study. Outcomes were evaluated from the Swedish Ventral Hernia Registry, by chart review, physical examination, and an abdominal wall complaints questionnaire. Results: The modified peritoneal flap hernioplasty group (n = 78) had larger hernias (mean width 10.4 vs 8.5 cm, p = 0.005), more advanced Centers for Disease Control classification (p = 0.009), and more simultaneous gastrointestinal-tract surgery (23.1% vs 11.5%, p = 0.041) than the retromuscular group (n = 96). No difference in short-term complications was seen. Incisional hernia recurrence was lower in the modified peritoneal flap hernioplasty group (1.4% vs 10.3%, p = 0.023), and patients were more satisfied (93.8% vs 81.7%, p = 0.032). Follow-up time was shorter in the modified peritoneal flap hernioplasty group (614 vs 1171 days, p < 0.001). Conclusion: This retrospective study showed similar rates of short-term complications, despite more complex hernias in the modified peritoneal flap hernioplasty group. Furthermore, a lower incisional hernia recurrence rate for the modified peritoneal flap hernioplasty technique compared with the retromuscular technique used in our department was found. If this holds true with equally long follow-up remains to be proven.

(författare) Main Clinical Use of Additive Manufacturing (Three-Dimensional Printing) in Finland Restricted to the Head and Neck Area in 2016-2017 2020 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267. ; 109:2, s. 166-173 Tidskriftsartikel (refereegranskat)abstract Additive manufacturing or three-dimensional printing is a novel production methodology for producing patient-specific models, medical aids, tools, and implants. However, the clinical impact of this technology is unknown. In this study, we sought to characterize the clinical adoption of medical additive manufacturing in Finland in 2016–2017. We focused on non-dental usage at university hospitals. Materials and Methods: A questionnaire containing five questions was sent by email to all operative, radiologic, and oncologic departments of all university hospitals in Finland. Respondents who reported extensive use of medical additive manufacturing were contacted with additional, personalized questions. Results: Of the 115 questionnaires sent, 58 received answers. Of the responders, 41% identified as non-users, including all general/gastrointestinal (GI) and vascular surgeons, urologists, and gynecologists; 23% identified as experimenters or previous users; and 36% identified as heavy users. Usage was concentrated around the head area by various specialties (neurosurgical, craniomaxillofacial, ear, nose and throat diseases (ENT), plastic surgery). Applications included repair of cranial vault defects and malformations, surgical oncology, trauma, and cleft palate reconstruction. Some routine usage was also reported in orthopedics. In addition to these patient-specific uses, we identified several off-the-shelf medical components that were produced by additive manufacturing, while some important patient-specific components were produced by traditional methodologies such as milling. Conclusion: During 2016–2017, medical additive manufacturing in Finland was routinely used at university hospitals for several applications in the head area. Outside of this area, usage was much less common. Future research should include all patient-specific products created by a computer-aided design/manufacture workflow from imaging data, instead of concentrating on the production methodology.

(författare) Splenic flexure mobilization and anastomotic leakage in anterior resection for rectal cancer: A multicentre cohort study. 2023 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 112:4, s. 246-255 Tidskriftsartikel (refereegranskat)abstract Some colorectal surgeons advocate routine splenic flexure mobilization (SFM) when performing anterior resection for rectal cancer to ensure a tension-free anastomosis. Meta-analyses of smaller studies suggest that this approach does not influence anastomotic leakage rates, but larger multicentre studies are needed to confirm the safety of a selective strategy. The aim of this study is to evaluate the impact of SFM on anastomotic leakage.This is a retrospective multicentre cohort study, comprising 1109 patients operated with anterior resection for rectal cancer in 2014-2018. Exposure was SFM, while anastomotic leakage within a year constituted the outcome. Stratified analyses were performed for type of mesorectal excision and surgical approach, as well as sensitivity analysis considering vascular tie placement. Multivariable Cox regression with hazard ratios (HRs) and 95% confidence intervals (CIs) was employed to adjust for confounding, while multiple imputation was used for missing data.SFM was performed in 381 patients (34.4%). Anastomotic leakage occurred in 83 (21.8%) and 123 (20.3%) patients operated with and without SFM, respectively. SFM was neither clearly detrimental nor beneficial regarding anastomotic leakage (adjusted HR = 0.82; 95% CI: 0.59-1.15), with no apparent differences for total or partial mesorectal excision and minimally invasive or open surgery. Concurrent high vascular ligation did not impact these results, and there was no evidence of interaction from centers with a more common use of SFM.SFM did not seem to influence the risk of anastomotic leakage after anterior resection for rectal cancer, regardless of type of mesorectal excision, use of minimally invasive surgery, or high vascular ligation.

(författare) Surgical exploration without resection in pancreatic and periampullary tumors : report from a national database 2021 Ingår i: Scandinavian Journal of Surgery. - : SAGE Publications. - 1457-4969 .- 1799-7267. ; 110:3, s. 344-350 Tidskriftsartikel (refereegranskat)abstract Background and Aims: Pancreatic and periampullary cancers are sometimes found to have a too advanced disease during surgery to allow resection. The aim was to describe characteristics, treatment, outcome, and time trends for patients that were planned for pancreatic surgery but found unresectable during surgery. Material and Methods: Data from the Swedish National Pancreatic and Periampullary Cancer Registry were used. All patients registered between January 2010 and August 2018 were included. The patient cohort was divided in two halves based on year of diagnosis. Results: In total, 12,377 patients were included in the registry and finally 4568 patients were scheduled for surgery. During surgical exploration, 3879 (84.9%) patients underwent pancreatic resection, 658 (14.4%) patients were found unresectable, and 31 (0.7%) had no pancreatic resection due to other reasons (e.g. benign lesion, comorbidity). More patients underwent surgical exploration and resection during the second time period, but exploration without resection was unchanged (15.7% vs 13.7%; p = 0.062). Survival rates were lower among the unresectable patients with pancreatic and periampullary tumors compared to the resectable patients, including 30-day mortality (n = 17 (3.5%) vs n = 39 (1.6%), p = 0.004) and 90-day mortality (n = 72 (15.0%) vs n = 70 (2.8%), p < 0.001). Palliative surgery became less common during the second half of the time period (p < 0.001). Conclusion: Unresectability is associated with an unfavorable prognosis. The frequency did not decrease during the study period, but palliative surgical procedures became less common.

The aim of this study was to determine the incidence and trends of femoral fractures among children and adolescents hospitalized between 1998 and 2016 in Finland and Sweden. Methods: All patients younger than 17 years of age in Finland and Sweden with a femoral fracture treated surgically between 1998 and 2016 were included in the study. Data were collected from National Hospital Discharge Registries. Patients were classified by gender and age into four groups. The annual incidences per 100,000 were calculated using annual mid-year population census data obtained from the Official Statistics of Finland and Sweden. Results: In total, 6410 patients younger than 17 years of age diagnosed with femoral fracture were included in this study. The total incidence per 100,000 femoral fractures was 13.3 in Finland and 11.0 in Sweden. The incidence of femoral fractures decreased during the study period in all age groups, except for teenage Finnish girls. Most of the fractures were located in femoral shaft. Fractures of the upper and distal femur were rare. Male predominance was detected in all age groups older than 1 year. Conclusions: The incidence of femoral fractures decreased in all age groups except in teenage Finnish girls. Majority of femoral fractures were located in femoral shaft with male predominance. In children younger than 1 year of age, female predominance was found.

(författare) Impact of the COVID-19 pandemic on the management of gallstone surgery: A Swedish population-based study. 2022 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267 .- 1457-4969. ; 111:1 Tidskriftsartikel (refereegranskat)abstract The SARS-CoV-2 pandemic has had a significant impact on healthcare delivery. As resources are reallocated, surgery for benign conditions such as gallstone disease is often given low priority. We do not know how this has affected the risk of patients with uncomplicated gallstone disease to develop acute cholecystitis, biliary pancreatitis, or obstructive jaundice.The study was based on the population-based Swedish Register of Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography. The period prior to the first cases of COVID-19 in Sweden, that is, April 2015-March 2020, was compared to the period April 2020-March 2021 during the pandemic. Stratification was made for factors potentially related to priority decisions.Altogether, 78,211 procedures were performed during the period of the study. The ratio of procedures performed during April 2020-March 2021 in the previous 5 years was 0.960 (p = 0.113). The ratio of procedures on patients aged <65 years was 0.945 (p = 0.008), on patients aged 65-80 years was 0.964 (p = 0.423), on patients aged >80 years was 1.336 (p = 0.025), on men was 1.001 (p = 0.841), on women was 0.934 (p = 0.006), on procedures completed laparoscopically was 0.964 (p = 0.190), on procedures completed with open approach was 0.659 (p = 0.044), on acute procedures was 1.218 (p = 0.016), on planned procedures was 0.791 (p < 0.001), on procedures performed for biliary colic was 0.808 (p < 0.001), on procedures performed for acute cholecystitis was 1.274 (p = 0.012), for biliary pancreatitis was 1.192 (p = 0.037), and for obstructive jaundice was 1.366 (p = 0.008).The COVID-19 has had a great impact on how gallstone surgery has been organized over the last 2 years. The decreased number of planned procedures probably reflects the reallocation of resources during the pandemic. However, whether the increasing number of acute procedures is the result of postponed planned surgery or a continuation of a long-term trend toward more acute surgery remains unanswered. Further studies are needed to assess and evaluate how this has affected public health and health economics.

This is the first prospective randomized study in adults comparing PEG with radiologically inserted gastrostomy (RIG).Methods:Randomization of 106 patients, eligible for both techniques, to PEG (pull method) or RIG. The groups were comparable in terms of age, body mass index, and underlying diseases. Adverse events were reported 10 and 30 days after the operative procedure, and mortality was up until 6 months. The validated European Quality of life 5 Dimensions 3 level version (EQ-5D) questionnaire was used for health status measurements.Results:The procedures were successfully completed in all patients. The median operative time was 10 min for PEG and 20 min for RIG (p < 0.001). The overall rate of adverse events was lower for PEG (22%) than for RIG (51%, p = 0.002), mostly due to less local self-limiting stoma reactions and tube problems. The 30-day mortality was lower after PEG (2% versus 14%, p = 0.020). Patient-scored health status remained low for the entire cohort, with an EQ-5D utility index of 0.164. Self-rated health was low but improved in the RIG group (52.5 from 41.1, out of 100).Conclusion:PEG can be recommended as the primary procedure in patients in need of a feeding gastrostomy, mainly due to a lower frequency of tube complications. However, as the two techniques complement each other, RIG is also a valid alternative method.

(författare) Long-term follow-up after surgical repair of abdominal rectus diastasis : a prospective randomized study 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:3, s. 283-289 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Abdominal rectus diastasis can lead to functional disability. There is no consensus regarding treatment. This was a prospective study on patients randomized to surgery using either Quill self-retaining sutures or retromuscular mesh for abdominal rectus diastasis repair. The primary aim of the study was to compare long-term recurrence after surgery. Secondary aims were abdominal muscle strength, pain, and quality of life.METHODS: A total of 57 patients were eligible and 52 were investigated. A routine 1-year follow-up ruled out any patient with recurrence and this was followed up by clinical examination for recurrence and assessment of the secondary outcomes a median of 5 years (3.8-6.5 years) after surgery. Quality of life was assessed using the Short Form-36 questionnaire. Pain related to activity was evaluated using the Ventral Hernia Pain Questionnaire.RESULTS: No recurrence of abdominal rectus diastasis was found. Significant improvements were seen between index surgery and long-term follow-up in all domains of Short Form-36. There were no significant differences in quality of life or self-reported muscle strength between the two surgical groups. Long-term pain remained unchanged compared to that at the 1-year follow-up. "Pain this week" had decreased significantly at long-term follow-up compared to prior to surgery (mesh p = 0.009, Quill p = 0.003).CONCLUSION: No recurrence of abdominal rectus diastasis appeared. There was no difference in quality of life or long-term pain between the two surgical groups. Implantation of retromuscular mesh entails more extensive surgery implying potentially higher risk for complications. This leads us to recommend reconstruction with double-row self-retaining sutures for the repair of abdominal rectus diastasis in patients with functional disability.

(författare) Practice patterns in diagnostics, staging, and management strategies of gallbladder cancer among Nordic tertiary centers 2023 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 112:3 Tidskriftsartikel (refereegranskat)abstract Background and objective: Gallbladder cancer (GBC) is a rare malignancy in the Nordic countries and no common Nordic treatment guidelines exist. This study aimed to characterize the current diagnostic and treatment strategies in the Nordic countries and disclose differences in these strategies. Methods: This was a survey study with a cross-sectional questionnaire of all 19 university hospitals providing curative-intent surgery for GBC in Sweden, Norway, Denmark, and Finland. Results: In all Nordic countries except Sweden, neoadjuvant/downstaging chemotherapy was used in GBC patients. In T1b and T2, majority of the centers (15-18/19) performed extended cholecystectomy. In T3, majority of the centers (13/19) performed cholecystectomy with resection of segments 4b and 5. In T4, majority of the centers (12-14/19) chose palliative/oncological care. The centers in Sweden extended lymphadenectomy beyond the hepatoduodenal ligament, whereas all other Nordic centers usually limited lymphadenectomy to the hepatoduodenal ligament. All Nordic centers except those in Norway used adjuvant chemotherapy routinely for GBC. There were no major differences between the Nordic centers in diagnostics and follow-up. Conclusions: The surgical and oncological treatment strategies of GBC vary considerably between the Nordic centers and countries.

Materials and methods: In this review, we tried to summarize the current evidence on non-surgical treatment trying to suggest a practical approach to the management of chronic pancreatitis. Results: Besides the unclear pathophysiological mechanism and a poorly unknown epidemiology, chronic pancreatitis is a complex syndrome that displays different possible challenges for physicians. Despite being traditionally considered as a benign disease, chronic pancreatitis encompasses 10-year mortality rates which are superior to the ones reported for some of the most common cancers. Conclusions: Chronic pancreatitis encompasses the management of multiple and complex medical co-morbidities that needs to be understood and addressed in a multidisciplinary specialist context.

(författare) Impact of immunohistochemistry on the diagnosis and management of primary aldosteronism: An important tool for improved patient follow-up 2020 Ingår i: Scandinavian journal of surgery : SJS : official organ for the Finnish Surgical Society and the Scandinavian Surgical Society. - : SAGE Publications. - 1799-7267. ; 109:2, s. 133-142 Tidskriftsartikel (refereegranskat)abstract Primary aldosteronism is a common cause of secondary hypertension. Primary aldosteronism is caused by an aldosterone-producing adenoma or bilateral hyperplasia that in some cases is asymmetrical with one adrenal dominating aldosterone secretion. Most patients with aldosterone-producing adenoma are biochemically cured by unilateral adrenalectomy, but patients with bilateral hyperplasia have a significant risk of residual or recurrent disease. Here, immunohistochemistry of CYP11B1 and B2 was used to investigate whether these markers could aid in the diagnostic workup of primary aldosteronism patients. Materials and Methods: A total of 39 patients with primary aldosteronism who underwent unilateral adrenalectomy for a presumed adenoma during 2013–2016 were included. Immunohistochemistry using monoclonal antibodies identifying the enzymes CYP11B1 and B2 was part of routine histopathological workup in 6 cases; in 33 cases, it was applied retrospectively. The hyperplasia diagnosis was suggested when there was no dominating nodule but immunoreactivity for CYP11B2 was seen in several nodules, which were also seen on routine sections. To distinguish between adenoma and hyperplasia, a ratio between the largest and second largest CYP11B2-positive nodules was calculated. Results: In all, 22 patients had an aldosterone-producing adenoma, while 13 patients were judged to have hyperplasia. In four cases, a final diagnosis could not be established, thus these were judged equivocal. Among the 33 cases investigated retrospectively, the primary histopathological diagnosis was altered from hyperplasia to aldosterone-producing adenoma in 9 cases (27%) after immunohistochemistry, and the immunohistochemically rectified adenoma group displayed improved clinical cure rates compared to the routine H&E-diagnosed cohort. Moreover, the B2 ratio was significantly higher in adenoma than in hyperplasia and equivocal cases. Conclusion: Immunohistochemistry detecting CYP11B1 and B2 expression is of great help in establishing a final histopathological diagnosis in patients with primary aldosteronism. This procedure should be part of the histopathological routine in all operated primary aldosteronism patients.

(författare) Management and risk of upgrade of atypical ductal hyperplasia in the breast : a population-based retrospective cohort study 2024 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. Tidskriftsartikel (refereegranskat)abstract Background: International guidelines recommend open surgery for atypical ductal hyperplasia (ADH) in the breast due to risk of underestimating malignant disease. Considering the ongoing randomized trials of active surveillance of low-risk ductal carcinoma in situ (DCIS), it seems reasonable to define a low-risk group of women with ADH where a conservative approach is appropriate. The aim here was to evaluate the management and risk for upgrade of lesions diagnosed as ADH in percutaneous breast biopsies in two Swedish hospitals.Methods: All women with a screen-detected or symptomatic breast lesion breast imaging-reporting and data system (BI-RADS) 2–4 and a percutaneous biopsy showing ADH between 2013 and 2022 at Sundsvall Hospital and Umeå University Hospital were included. Information regarding imaging, histopathology, clinical features, and management was retrieved from medical records. Odds ratio (OR) and 95% confidence intervals (CI) for upgrade to malignant diagnosis after surgery were calculated by logistic regression analysis.Results: Altogether, 101 women were included with a mean age 56.1 (range 36–93) years. Most women were selected from the national mammography screening program due to microcalcifications. Biopsies were performed with vacuum-assisted biopsy (60.4%) or core-needle biopsy (39.6%). Forty-eight women (47.5%) underwent surgery, of which 11 were upgraded to DCIS, and 7 to invasive breast cancer (upgrade rate 37.5%). Among the 53 women managed conservatively (median follow-up 74 months), one woman (1.9%) developed subsequent ipsilateral DCIS. The combined upgrade rate was 18.8%. No clinical variable statistically significantly correlating to risk of upgrade was identified.Conclusions: The upgrade rate of 37.5% in women undergoing surgery compared to an estimated 5-year risk of ipsilateral malignancy at 1.9% in women managed conservatively indicate that non-surgical management of select women with ADH is feasible. Research should focus on defining reproducible criteria differentiating high-risk from low-risk ADH.

(författare) Patient-Reported Long-Term Outcome is Superior After Treatment with Self-Expanding Metallic Stents in Esophageal Perforations 2021 Ingår i: Scandinavian Journal of Surgery. - : Sage Publications. - 1457-4969 .- 1799-7267. ; 110:2, s. 222-226 Tidskriftsartikel (refereegranskat)abstract BACKGROUND AND AIMS: Esophageal perforations are life threatening. Since the 1990s, placing of covered esophageal stents has become an alternative to surgery. Theoretically, this minimally invasive approach has several benefits; however, little data are available on long-term outcome in these patients. We aimed to evaluate how patient-reported outcome differed between full surgery and placement of self-expanding metallic stents when treating primary benign esophageal perforations.MATERIAL AND METHODS: Of 48 patients treated at our hospital in 2000-2015, 23 were alive and asked to answer three questionnaires. We used a short clinical questionnaire, the QLQ-OG25 from the European Organization for Research and Treatment of Cancer and a simplified quality-of-life instrument, the Check Your Health. Non-parametric statistics were used to evaluate differences between the two groups.RESULTS: In all, 20 (87%) individuals (13 men, 64 years of age) responded. At survey, surgical patients had lost 13 kg of initial weight, compared to no weight loss in the self-expanding metallic stents group (p = 0.01). This involuntary weight loss worried patients according to the QLQ-OG25; otherwise patient-experience measures did not differ between groups. For quality of life, surgical patients scored significantly lower physical health, emotional well-being, social functioning, and overall quality of life after treatment, but after stenting no differences were seen.CONCLUSIONS: In contrast to stenting, surgical treatment was associated with involuntary, and worrisome, weight loss as well as reduced quality of life. We therefore believe that self-expanding metallic stents should be used when possible in treating benign esophageal perforations.
