- Background: The total cost of bile duct injuries (BDIs) in an unselected national cohort of patients undergoing cholecystectomy are unknown. The aim was to evaluate costs associated with treatment of cholecystectomy-related BDIs and to calculate cost effectiveness of routine vs. on-demand intraoperative cholangiography (IOC). Methods: Data from Swedish patients suffering a BDI during a 5 year period were analysed. Questionnaires to investigate loss-of-production and health status (EQ-5D) were distributed to patients who suffered a BDI during cholecystectomy and who underwent uneventful cholecystectomy (matched control group). Costs per quality-adjusted-life-year (QALY) gained by intraoperative diagnosis were estimated for two strategies: routine versus on-demand IOC during cholecystectomy. Results: Intraoperative diagnosis, immediate intraoperative repair, and minor BDI were all associated with reduced direct treatment costs compared to postoperative diagnosis, delayed repair, and major BDI (all p < 0.001). No difference was noted in loss-of-production for minor versus major BDIs or between different treatment strategies. The cost per QALY gained with routine intraoperative cholangiography (ICER-incremental cost-effectiveness ratio) to achieve intraoperative diagnosis was €50,000. Conclusions: Intraoperative detection and immediate intraoperative repair is the superior strategy with less than half the cost and superior functional patient outcomes than postoperative diagnosis and delayed repair. The cost per QALY gained (ICER) using routine IOC was considered reasonable.

- Background: The Shouldice technique is the 'gold standard' of open non-mesh hernia repair. The aim of this study was to compare 5-year recurrence rates after Shouldice and laparoscopic transabdominal preperitoneal patch (TAPP) repair for primary inguinal hernia. Method: Men with a primary unilateral inguinal hernia were randomized to either Shouldice or TAPP operation. An independent observer scored the surgeons' performance. Follow-up comprised clinical examination after 1 year, a questionnaire after 2 and 3 years, and a clinical examination after 5 years. Results: Between February 1993 and March 1996, 1183 patients were included. Nine hundred and twenty patients were followed for 5 years, 454 in the TAPP group and 466 in the Shouldice group. Recurrences were evenly distributed between groups throughout the follow-up period. The cumulative recurrence rate after 5 years was 6.6 per cent in the TAPP group and 6.7 per cent in the Shouldice group. Postoperative pain was a risk factor for recurrence after Shouldice operation but not after TAPP repair. There was a correlation between a low surgeon's performance score and recurrence. Conclusion: The 5-year recurrence rate is acceptable, with no difference between TAPP and Shouldice repair. Poor operative performance resulted in a higher recurrence rate. The TAPP operation represents an excellent alternative for primary inguinal hernia repair.

- Background: Inguinal hernia repair is the most common operation in general surgery. Prosthetic reinforcement of the inguinal area with polypropylene mesh has increased dramatically in the last decade. The aim of this study was to evaluate how different types of mesh affect the spermatic cord structures. Methods: Thirty rats were divided into three groups. The spermatic cord was dissected free and a conventional suture repair was performed in group I, an operation mimicking the Lichtenstein operation with a heavyweight polypropylene mesh in group II and the same operation using large pore, lightweighted polypropylene/polyglactin composite mesh in group III. A vasography was performed after 90 days. The cross-sectional area of the vas deferens and s-testosterone from the spermatic vein were measured using the contralateral side as control. Light microscopy of the inguinal canal was performed and inflammation and fibrosis were graded. Results: Vasography revealed patent vas deferens in all animals. In group III, there was a lower s-testosterone in the spermatic vein and a reduced cross-sectional area of the vas deferens on the operated compared to the control side. However, there was no difference in the other groups and there was no significant difference in s-testosterone levels between the groups. There was significantly more inflammation and fibrosis after mesh repair compared to suture repair, but there was no difference between the two mesh groups. Unexpectedly, polyglactin fibres were still seen in specimens in group III after 90 days. Conclusion: In conclusion, the only effect on the spermatic cord structures in a rat model is seen as an impaired s-testosterone production and a reduced cross-sectional area of the vas deferens after use of a low-weight composite mesh compared to the control side. No difference in inflammation or fibrosis was found between heavyweight polypropylene mesh and low-weight composite mesh. Copyright (C) 2004 S. Karger AG, Basel.

Tidskriftsartikel (refereegranskat)abstract
- Open abdomen (OA) therapy frequently results in a giant planned ventral hernia. Vacuum-assisted wound closure and mesh-mediated fascial traction (VAWCM) enables delayed primary fascial closure in most patients, even after prolonged OA treatment. Our aim was to study the incidence of hernia and abdominal wall discomfort 1 year after abdominal closure. A prospective multicenter cohort study of 111 patients undergoing OA/VAWCM was performed during 2006-2009. Surviving patients underwent clinical examination, computed tomography (CT), and chart review at 1 year. Incisional and parastomal hernias and abdominal wall symptoms were noted. The median age for the 70 surviving patients was 68 years, 77 % of whom were male. Indications for OA were visceral pathology (n = 40), vascular pathology (n = 22), or trauma (n = 8). Median length of OA therapy was 14 days. Among 64 survivors who had delayed primary fascial closure, 23 (36 %) had a clinically detectable hernia and another 19 (30 %) had hernias that were detected on CT (n = 18) or at laparotomy (n = 1). Symptomatic hernias were found in 14 (22 %), 7 of them underwent repair. The median hernia widths in symptomatic and asymptomatic patients were 7.3 and 4.8 cm, respectively (p = 0.031) with median areas of 81.0 and 42.9 cm(2), respectively (p = 0.025). Of 31 patients with a stoma, 18 (58 %) had a parastomal hernia. Parastomal hernia (odds ratio 8.9; 95 % confidence interval 1.2-68.8) was the only independent factor associated with an incisional hernia. Incisional hernia incidence 1 year after OA therapy with VAWCM was high. Most hernias were small and asymptomatic, unlike the giant planned ventral hernias of the past.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Topical negative pressure (TNP) therapy is increasingly used in open abdomen management. It is not known to what extent this pressure propagates through the dressing to the bowel surface, potentially increasing the risk of bowel fistula formation. The present study in a porcine model was designed to evaluate pressure propagation. METHODS: A commercially available TNP therapy system (ABThera/VAC) was applied in six pigs after laparotomy. Pressure sensors were placed in predetermined positions in the dressing and in the abdominal cavity and the pressure was registered at TNP settings of -50, -75, -100, -125, and -150 mmHg. Next, after infusing 200 ml of saline into the abdomen through a catheter, the amount of fluid drained through the system during 10 min of TNP therapy was registered. Finally, pressure was measured above and below eight layers of paraffin gauzes during TNP therapy. RESULTS: Observed pressure within the outer two foams and the foam of the visceral protective layer correlated with preset TNP. The median pressure at the bowel surface was between -2 and -10 mmHg, regardless of preset TNP. Median fluid drainage was 95% of the infused fluid at -75 mmHg and 124% at -150 mmHg. Paraffin gauzes had a limited isolating effect, reducing the pressure by 13% in median. CONCLUSIONS: Negative pressure reaching the bowel surface during TNP therapy with the ABThera system is limited for all TNP levels. Reduced therapy pressure does not lead to reduced pressure at the bowel surface. The system drains the abdominal cavity completely of fluid. Paraffin gauzes are of limited value as a means of pressure isolation.

Tidskriftsartikel (refereegranskat)abstract
- Neuroinflammation is implicated in the development and maintenance of persistent pain states, but there are limited data linking cerebrospinal fluid (CSF) inflammatory mediators with neurophysiological pain processes in humans. In a prospective observational study, CSF inflammatory mediators were compared between patients with osteoarthritis (OA) who were undergoing total hip arthroplasty due to disabling pain symptoms (n = 52) and pain-free comparison controls (n = 30). In OA patients only, detailed clinical examination and quantitative sensory testing were completed. Cerebrospinal fluid samples were analyzed for 10 proinflammatory mediators using Meso Scale Discovery platform. Compared to controls, OA patients had higher CSF levels of interleukin 8 (IL-8) (P = 0.002), intercellular adhesion molecule 1 (P = 0.007), and vascular cell adhesion molecule 1 (P = 0.006). Osteoarthritis patients with central sensitization possibly indicated by arm pressure pain detection threshold <250 kPa showed significantly higher CSF levels of Fms-related tyrosine kinase 1 (Flt-1) (P = 0.044) and interferon gamma-induced protein 10 (IP-10) (P = 0.024), as compared to subjects with PPDT above that threshold. In patients reporting pain numerical rating scale score >/=3/10 during peripheral venous cannulation, Flt-1 was elevated (P = 0.025), and in patients with punctate stimulus wind-up ratio >/=2, CSF monocyte chemoattractant protein 1 was higher (P = 0.011). Multiple logistic regression models showed that increased Flt-1 was associated with central sensitization, assessed by remote-site PPDT and peripheral venous cannulation pain, and monocyte chemoattractant protein-1 with temporal summation in the area of maximum pain. Multiple proinflammatory mediators measured in CSF are associated with persistent hip OA-related pain. Pain phenotype may be influenced by specific CSF neuroinflammatory profiles.

Tidskriftsartikel (refereegranskat)abstract
- Persistent pain after groin hernia repair is a major health problem. Sleep disturbance is associated with heightened pain sensitivity. The main objective of this study was to examine the role of sleep disturbance in the development and long-term maintenance of chronic postherniorrhaphy inguinal pain (CPIP), with exploration of sex differences. From 2012 to 2017, a national cohort of patients with prior groin hernia repair (n = 2084;45.8% females) were assessed for the development of CPIP 12 months after surgery. Patients then underwent long-term (median 5.0 years) follow-up to evaluate the contribution of sex and sleep disturbance on the maintenance of CPIP. Associations between pre- and postoperative sleep problems (assessed at long-term follow-up) and CPIP were tested using logistic regression. Females had higher rates of CPIP with negative impact on daily activities 12 months after surgery as compared to males (14.6 vs 9.2%, P < .0005), and were more likely to have moderate-severe CPIP in the long-term (3.1 vs 1.2%, P = .003). Preoperative sleep problems predicted development of CPIP 12 months after surgery (adjusted odds ratio [aOR] 1.76 [95%CI 1.26-2.46], P = .001) and CPIP in the long-term (aOR 2.20 [1.61-3.00] , P < .0001). CPIP was associated with insomnia and depression. Sleep disturbance may increase the risk for CPIP, and contribute to maintenance of postsurgical pain. PERSPECTIVE: Females are at heightened risk for CPIP as compared to males. Increased severity of pain symptoms are linked to poorer sleep and psychiatric morbidity. Given the robust associations between sleep disturbance and CPIP, interventions which consolidate and promote sleep, especially in females, may improve long-term pain control.

Environmental impact of single-use, reusable, and mixed trocar systems used for laparoscopic cholecystectomies
- 2022

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Climate change is one of the 21st century's biggest public health issues and health care contributes up to 10% of the emissions of greenhouse gases in developed countries. About 15 million laparoscopic procedures are performed annually worldwide and single-use medical equipment is increasingly used during these procedures. Little is known about costs and environmental footprint of this change in practice.METHODS: We employed Life Cycle Assessment method to evaluate and compare the environmental impacts of single-use, reusable, and mixed trocar systems used for laparoscopic cholecystectomies at three hospitals in southern Sweden. The environmental impacts were calculated using the IMPACT 2002+ method and a functional unit of 500 procedures. Monte Carlo simulations were used to estimate differences between trocar systems. Data are presented as medians and 2.5th to 97.5th percentiles. Financial costs were calculated using Life Cycle Costing.RESULTS: The single-use system had a 182% higher impact on resources than the reusable system [difference: 5160 MJ primary (4400-5770)]. The single-use system had a 379% higher impact on climate change than the reusable system [difference: 446 kg CO2eq (413-483)]. The single-use system had an 83% higher impact than the reusable system on ecosystem quality [difference: 79 PDF*m2*yr (24-112)] and a 240% higher impact on human health [difference: 2.4x10-4 DALY/person/yr (2.2x10-4-2.6x10-4)]. The mixed and single-use systems had a similar environmental impact. Differences between single-use and reusable trocars with regard to resource use and ecosystem quality were found to be sensitive to lower filling of machines in the sterilization process. For ecosystem quality the difference between the two were further sensitive to a 50% decrease in number of reuses, and to using a fossil fuel intensive electricity mix. Differences regarding effects on climate change and human health were robust in the sensitivity analyses. The reusable and mixed trocar systems were approximately half as expensive as the single-use systems (17360 € and 18560 € versus 37600 €, respectively).CONCLUSION: In the Swedish healthcare system the reusable trocar system offers a robust opportunity to reduce both the environmental impact and financial costs for laparoscopic surgery.

-
Ingår i: World Journal of Surgery. - : Springer Science and Business Media LLC. - 0364-2313 .- 1432-2323. ; 44:1, s. 95-99

Tidskriftsartikel (refereegranskat)abstract
- Introduction: A laparotomy is commonly required to gain abdominal access. A safe standardized access and closure technique is warranted to minimize abdominal wall complications like wound infections, burst abdomen and incisional hernias. Stitches are recommended to be small and placed tightly, obtaining a suture length-to-incision length (SL/WL) ratio of ≥ 4:1. This can be time-consuming and difficult to achieve especially following long trying surgical procedures. The aim was to develop and evaluate a new mechanical suture device for standardized wound closure. Methods: A mechanical suture device (Suture-tool) was developed in collaboration between a medical technology engineer team with the aim to achieve a standardized suture line of high quality that could be performed speedy and safe. Ten surgeons closed an incision in an animal tissue model after a standardized introduction of the instrument comparing the device to conventional needle driver suturing (NDS) using the 4:1 technique. Outcome measures were SL/WL ratio, number of stitches and suture time. Results: In total, 80 suture lines were evaluated. SL/WL ratio of ≥ 4 was achieved in 95% using the Suture-tool and 30% using NDS (p < 0,001). Number of stitches was similar. Suture time was 30% shorter using the Suture-tool compared to NDS (2 min 54 s vs. 4 min 5 s; p < 0.001). Conclusions: The mechanical needle driver seems to be a promising device to perform a speedy standardized high-quality suture line for fascial closure.

Suture-TOOL : A suturing device for swift and standardized abdominal aponeurosis closure
- 2022
-
Ingår i: Surgery in Practice and Science. - : Elsevier BV. - 2666-2620. ; 11
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: Surgeons can reduce incisional hernia formation by adhering to standardized techniques for incisional wound closure. This is often neglected by the time a long operation is to be ended and can lead to the risk of developing an incisional hernia or a wound rupture. To address this issue, a suturing machine (Suture-TOOL) was developed for swift and standardized abdominal closure. The aim was to compare the user safety, speed, and suturing quality between Suture-TOOL and manual Needle-Driver suturing. Method: Fifteen surgeons who were specialists in surgery, urology, and gynaecology as well as surgical trainees were invited. The Suture-TOOL was presented to the surgeons who read the instructions for use before starting the test. Each surgeon closed nine 15 cm-long incisions in a human body model; six with Suture-TOOL and three with the Needle-Driver technique. Gloves were examined for puncture damage. Endpoints were suture-length/wound-length (SL/WL)-ratio, closure time, number of stitches, learning curve, and glove puncture rate. A VAS-evaluation concerning different Suture-Tool user impressions was completed. Results: A SL/WL-ratio ≥4 was 98% for Suture-TOOL versus 69% for Needle-Driver (p < 0.001). Suture time was shorter for Suture-TOOL (p < 0.001). Wound stitch count was higher for Needle-Driver (p = 0.013). The median SL/WL-ratio was similar between groups. The learning curve plateaued after three closures using Suture-TOOL. Two glove punctures were detected—all in the Needle-Driver group. Suture-TOOL received high VAS scores for all measured functionalities. Conclusion: Suture-TOOL is a promising device for clinical use. It is safe, easy, and fast resulting in a high-quality suture lines with a short learning curve and a high functionality ranking.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Groin hernias in women is much less common than in men; it constitutes only 9% of all groin hernia operations. Historically, studies have been performed on men and the results applied to both genders. However, prospectively registered operations within national registers have contributed to new knowledge regarding groin hernias in women. The aim of this paper was to investigate and present a body of literature based upon the Swedish Hernia Register together with recent data from the register's annual report. Patients and Methods: PubMed and Embase were searched for studies based on the Swedish Hernia Register between 1992 and 2023. Based on the initial reading of abstracts, studies that presented results separately for women were selected and read. Recent data were acquired from the 2022 annual report of the Swedish Hernia Register. Results: A total of 73 studies of interest were identified. Of these, 52 included women, but only 19 presented separate results for women. Four themes emerged and were analysed further: emergency surgery and mortality, femoral hernias, the risk of reoperation for recurrence, and chronic pain following female groin hernia repairs. Discussion: Studies from the Swedish Hernia Register clearly describe that both the presentation of hernias and outcomes after repair differ significantly between the two genders. The differences that have been identified over the years have been incorporated into the national guidelines. Register data indicates that the guidelines have been implemented and are fairly well adhered to. As a result, significant improvements in outcomes regarding recurrences have been made for women with groin hernias in Sweden.

Forskningsöversikt (refereegranskat)abstract
- The Swedish Hernia Register (SHR) is a national quality register with more than 350,000 prospectively registered groin hernia repairs. Studies from the SHR have addressed important and clinically relevant issues within the field of laparoscopic groin hernia surgery and the aim of this paper is to present five of the most innovative patient-oriented publications including analysis of laparoscopic hernia repairs based on data retrieved from the SHR published between 2010 and 2020. After a Medline search was conducted, papers were graded and five papers were selected because of their specific nature, quality of methodology or international interest. The papers in our review studied a wide range of topics such as the risk of male infertility after mesh repair, risk of groin hernia surgery after open and minimally invasive prostatectomy, chronic pain after groin hernia surgery vs. method of repair, gender differences in risk of reoperation vs. method of repair and risk of reoperation vs. low and high molecular weight of the mesh. When gathering large amount of high-quality data, including almost total national coverage of all inguinal surgeries performed, it is possible to make valid conclusions and recommendation even on rare conditions and to sort out techniques that does not perform as intended, or does not apply to specific clinical situations. The studies above show that a laparoscopic repair is associated with a decreased risk of chronic pain for both gender to the price of a significantly higher risk of reoperation in men. The contrary is shown in women with a decreased risk of reoperation using laparoscopic repair compared to open repair.

A cost-minimisation analysis comparing TEP with Lichtenstein for treatment of inguinal hernia in Sweden
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: Laparoscopic surgery has emerged as a new treatment modality for inguinal hernia. It is important to analyse its long-term costs in relation to other methods.Methods: A randomized multicenter study comparing totally extraperitoneal laparoscopic repair (TEP) with open repair according to Lichtenstein was performed on men with a primary inguinal hernia. Long-term follow-up collecting data on recurrences and complications up to five years after operation was carried out. Taking treatment costs into consideration, a cost-minimisation analysis was conducted.Results: Altogether 1370 patients were operated, 665 in the TEP and 705 in the Lichtenstein group. The total hospital cost for the index operation was €710.6 higher for TEP (P<0.001). Including costs for recurrences and complications, this difference increased to €795.1 (P<0.001). Taking community costs into account, the difference decreased with €503.1 to €292.0 (P=0.024).Conclusion: With five-year follow-up including complication, reoperation and community costs, there was a small but significant difference in total costs between the two methods.

Laparoscopic or Open Inguinal Hernia Repair - Which is Best for the Patient?
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Inguinal hernia repair is the most common operation in general surgery. Its main challenge is to achieve low recurrence rates. With the introduction of mesh implants, first in open and later in laparoscopic repair, recurrence rates have decreased substantially. Therefore, the focus has been shifted from clinical outcome, such as recurrence, towards patient-experienced endpoints, such as chronic pain. In order to compare the results of open and laparoscopic hernia repair, a randomised multicentre trial - the Swedish Multicentre trial of Inguinal hernia repair by Laparoscopy (SMIL) - was designed by a study group from 11 hospitals. Between November 1996 and August 2000, 1512 men aged 30-70 years with a primary inguinal hernia were randomised to either laparoscopic (TEP, Totally ExtraPeritoneal) or open (Lichtenstein) repair. The primary endpoint was recurrence at five years. Secondary endpoints were short-term results, frequency of chronic pain and a cost analysis including complications and recurrences up to five years after surgery. In total, 1370 patients, 665 in the TEP and 705 in the Lichtenstein group, underwent operation. With 94% of operated patients available for follow-up after 5.1 years, the recurrence rate was 3.5% in the TEP and 1.2% in the Lichtenstein group. Postoperative pain was lower in the TEP group up to 12 weeks after operation, resulting in five days less sick leave and 11 days shorter time to full recovery. Patients in the TEP group had a slightly increased risk of major complications. Chronic pain was reported by 9-11% of patients in the TEP and 19-25% in the Lichtenstein group at the different follow-up points. Hospital costs for TEP were higher than for Lichtenstein, while community costs were lower due to shorter sick leave. By avoiding disposable laparoscopic equipment, the cost for TEP would be almost equal compared with Lichtenstein. In conclusion, both TEP and Lichtenstein repair have advantages and disadvantages for the patient. Depending on local resources and expertise both methods can be used and recommended for primary inguinal hernia repair.

- Objectives: To compare a laparoscopic (totally extraperitoneal patch (TEP)) and an open technique (Lichtenstein) for inguinal hernia repair regarding recurrence rate and possible risk factors for recurrence. Summary Background Data: Laparoscopic hernia repair has been introduced as an alternative to open repair. Short-term follow-up suggests benefits for those patients operated with a laparoscopic approach compared with open techniques; ie, less postoperative pain and a shorter convalescence period. Long-term results, however, are less well known. Methods: The study was conducted as a multicenter randomized trial with a 5-year follow-up. A total of 1512 men aged 30 to 70 years, with a primary unilateral inguinal hernia, were randomized to either TEP or Lichtenstein repair. Results: Overall, 665 patients in the TEP group and 705 patients in the Lichtenstein group were evaluable. The cumulative recurrence rate was 3.5% in the TEP group and 1.2% in the Lichtenstein group (P = 0.008). Test for heterogeneity revealed significant differences between individual surgeons. The exclusion of 1 surgeon, who was responsible for 33% (7 of 21) of all recurrences in the TEP group, lowered the cumulative recurrence rate to 2.4% in this group, which was not statistically different from that of the Lichtenstein group. Conclusions: The recurrence rate for both TEP and Lichtenstein repair was low. A higher cumulative recurrence rate in the TEP group was seen at 5 years. Further analysis revealed that this could be attributable to incorrect surgical technique.

- BACKGROUND: The optimal treatment for recurrent inguinal hernia is of concern due to the high frequency of recurrence. METHODS: This randomized multicenter study compared the short- and long-term results for recurrent inguinal hernia repair by either the laparoscopic transabdominal preperitoneal patch (TAPP) procedure or the Lichtenstein technique. RESULTS: A total of 147 patients underwent surgery (73 TAPP and 74 Lichtenstein). The operating time was 65 min (range, 23-165 min) for the TAPP group and 64 min (range, 25-135 min) for the Lichtenstein group. Patients who underwent TAPP reported significantly less postoperative pain and shorter sick leave (8 vs 16 days). The recurrence rate 5 years after surgery was 19% for the TAPP group and 18% for the Lichtenstein group. CONCLUSION: The short-term advantage for patients who undergo the laparoscopic technique is less postoperative pain and shorter sick leave. In the long term, no differences were observed in the chronic pain or recurrence rate.
