- Purposede Garengeot's hernia is a rare entity in which the appendix is located within a femoral hernia and is almost invariably encountered incarcerated in an emergency setting with concomitant appendicitis. In the literature, there are mostly single-case reports. The purpose of the present study was to perform a review of the literature to study the incidence, pathogenesis, demographics, clinical presentation, laboratory and radiological investigations, differential diagnosis, delay in diagnosis and treatment, operative findings, surgical technique, histological findings, the postoperative course, use of antibiotics, and complications regarding de Garengeot's hernia.MethodsA literature search was performed through PubMed with the following search terms, single or in combination: Garengeot, femoral hernia, and appendicitis. Additional references were also found within the articles, and two patients from Uppsala University Hospital were added.ResultsBetween 1981 and 2016, 70 publications were identified, and with the additional two patients, the present series comprised 90 patients There were 75 women (median age 73.0years) and 15 men (median age 78.0years). On examination, an inguinal mass was found in 87 patients (97%), which was painful and the cause of primary complaint in 67 patients (74%): the median duration of symptoms was 3days. Radiological investigations or ultrasound were performed in 67 patients (74%); computed tomography was the most accurate with a positive diagnosis in 23/34 patients. Appendicitis was found in 76 patients, gangrenous in 23, and perforated in 9. The surgical approach was inguinal in 76 patients, including 15 with concomitant laparotomy. The preperitoneal route was chosen in six patients, and laparoscopy alone in four patients. A mesh/plug was used in 22 patients (7/22 normal appendix) and suture repair in 59 (4/59 normal appendix: p<0.01). Complications were analysed in 79 patients and occurred in 11%. There was no mortality.Conclusionsde Garengeot's hernia is rare, being indistinguishable from an incarcerated femoral hernia in general. A delay in surgery should be avoided but if needed, computed tomography may be used for differential diagnosis. Although there is no standard treatment, mesh material does not appear advisable in the presence of a perforation, and it is beneficial for the surgeons to perform their routine method rather than a specific technique.

- The main curative treatment modality for esophageal cancer is resection. Patients initially deemed suitable for resection may become unsuitable, most commonly due to signs of generalized disease or having become unfit for surgery. The aim was to assess risk factors for abandoning esophagectomy and its impact on survival. All patients diagnosed with an esophageal or gastroesophageal junction cancer in the Swedish National Register for Esophageal and Gastric Cancer from 2006-2016 were included and risk factors associated with becoming ineligible for resection were analyzed in multivariable logistic regression analysis. Overall survival was explored by multivariable Cox regression models. Among 1,792 patients planned for resection, 189 (11%) became unsuitable for resection before surgery and 114 (6%) had exploratory surgery without resection. Intermediate and high educational levels were associated with an increased probability of resection (odds ratio (OR) 1.46, 95% CI 1.05-2.05, OR 1.92, 95% CI 1.28-2.87, respectively) as was marital status (married: OR 1.37, 95% CI 1.01-1.85). Clinically advanced disease (cT4: OR 0.38, 95% CI 0.16-0.87; cN3: OR 0.27, 95% CI 0.09-0.81) and neoadjuvant treatment were associated with a decreased probability of resection (OR 0.62, 95% CI 0.46-0.88).Five-year survival for non-resected patients was only 4.5% although neoadjuvant treatment was associated with improved survival (HR 0.75, 95% CI 0.56-0.99). Non-resected patients with squamous cell carcinoma had comparatively reduced survival (HR 1.64, 95% CI 1.10-2.43). High socioeconomic status was associated with an increased probability of completing the plan to resect whereas clinically advanced disease and neoadjuvant treatment were independent factors associated with increased risk of abandoning resectional intent.

- Background Recent research indicates long-term survival benefits of minimally invasive esophagectomy (MIE) compared with open esophagectomy (OE) for patients with esophageal and gastroesophageal junction (GEJ) cancers, but there is a need for more population-based studies. Methods We conducted a prospective population-based nationwide cohort study including all patients in Sweden diagnosed with esophageal or junctional cancer who underwent a transthoracic esophagectomy with intrathoracic anastomosis. Data were collected from the Swedish National Register for Esophageal and Gastric Cancer in 2006-2019. Patients were grouped into OE and MIE including hybrid MIE (HMIE) and totally MIE (TMIE). Overall survival and short-term postoperative outcomes were compared using Cox regression and logistic regression models, respectively. All models were adjusted for age, sex, American Society of Anesthesiologists (ASA) score, clinical T and N stage, neoadjuvant therapy, year of surgery, and hospital volume. Results Among 1404 patients, 998 (71.1%) underwent OE and 406 (28.9%) underwent MIE. Compared with OE, overall survival was better following MIE (hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.55-0.94), TMIE (HR 0.67, 95% CI 0.47-0.94), and possibly also after HMIE (HR 0.76, 95% CI 0.56-1.02). MIE was associated with shorter operation time, less intraoperative bleeding, higher number of resected lymph nodes, and shorter hospital stay compared with OE. MIE was also associated with fewer overall complications (odds ratio [OR] 0.70, 95% CI 0.47-1.03) as well as non-surgical complications (OR 0.64, 95% CI 0.40-1.00). Conclusions MIE seems to offer better survival and similar or improved short-term postoperative outcomes in esophageal and GEJ cancers compared with OE in this unselected population-based cohort.

- Background Esophagectomy is the cornerstone in curative treatment for esophageal and gastroesophageal junctional cancer. Esophageal resection is an advanced procedure with many complications, whereof anastomotic leak is the most dreaded. This study aimed to monitor the microcirculation with microdialysis analysis of local lactate levels in real-time on both sides of the esophagogastric anastomosis in totally minimally invasive Ivor-Lewis esophagectomy. Materials and Methods Twenty-five patients planned for esophageal resection with gastric conduit reconstruction and intrathoracic anastomosis were recruited. A sampling device, the OnZurf(R) Probe, along with the CliniSenz(R) Analyser (Senzime AB, Uppsala Sweden) was utilized for measurements. Lactate levels from both sides of the anastomosis were analysed in real time, on site, by a transportable analyser device. Measurements were made every 30 min during the first 24 h, and thereafter every 2 hours for up to 4 days. Results All probes could be positioned as planned and on the third postoperative day 19/25 and 15/25 of the esophageal and gastric probes, respectively, continued to deliver measurements. In total, 89.6% (1539/1718) and 72.4% (1098/1516) of the measurements were deemed successful. The average lactate level on the esophageal side of the anastomosis and the gastric conduit ranged between 1.1-11.5 and 0.8-7.0 mM, respectively. Two anastomotic leaks occurred, one of which had persisting high lactate levels on the gastric side of the anastomosis. Conclusion Application and use of the novel CliniSenz(R) analyser system, in combination with the OnZurf(R) Probe was feasible and safe. Continuous monitoring of analytes from the perianastomotic area has the potential to improve care after esophageal resection.

Tidskriftsartikel (refereegranskat)abstract
- The Swedish National Register for Esophageal and Gastric cancer was launched in 2006 and contains data with adequate national coverage and of high internal validity on patients diagnosed with these tumors. The aim of this study was to describe the evolution of esophageal and gastric cancer care as reflected in a population-based clinical registry. The study population was 12,242 patients (6,926 with esophageal and gastroesophageal junction (GEJ) cancers and 5,316 with gastric cancers) diagnosed between 2007 and 2016. Treatment strategies, short- and long-term mortality, gender aspects, and centralization were investigated. Neoadjuvant oncological treatment became increasingly prevalent during the study period. Resection rates for both esophageal/GEJ and gastric cancers decreased from 29.4% to 26.0% (P=0.022) and from 38.8% to 33.3% (P=0.002), respectively. A marked reduction in the number of hospitals performing esophageal and gastric cancer surgery was noted. In gastric cancer patients, an improvement in 30-day mortality from 4.2% to 1.6% (P=0.005) was evident. Overall 5-year survival after esophageal resection was 38.9%, being higher among women compared to men (47.5 vs. 36.6%; P<0.001), whereas no gender difference was seen in gastric cancer. During the recent decade, the analyses based on the Swedish National Register for Esophageal and Gastric cancer database demonstrated significant improvements in several important quality indicators of care for patients with esophagogastric cancers. The Swedish National Register for Esophageal and Gastric cancer offers an instrument not only for the control and endorsement of quality of care but also a unique tool for population-based clinical research.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Only around one-quarter of patients with cancer of the oesophagus and the gastro-oesophageal junction (GOJ) undergo surgical resection. This population-based study investigated the rates of treatment with curative intent and resection, and their association with survival.METHODS: Patients diagnosed with oesophageal and GOJ cancer between 2006 and 2015 in Sweden were identified from the National Register for Oesophageal and Gastric Cancer (NREV). The NREV was cross-linked with several national registries to obtain information on additional exposures. The annual proportion of patients undergoing treatment with curative intent and surgical resection in each county was calculated, and the counties divided into groups with low, intermediate and high rates. Treatment with curative intent was defined as definitive chemoradiation therapy or surgery, with or without neoadjuvant oncological treatment. Overall survival was analysed using a multilevel model based on county of residence at the time of diagnosis.RESULTS: Some 5959 patients were included, of whom 1503 (25·2 per cent) underwent surgery. Median overall survival after diagnosis was 7·7, 8·8 and 11·1 months respectively in counties with low, intermediate and high rates of treatment with curative intent. Corresponding survival times for the surgical resection groups were 7·4, 9·3 and 11·0 months. In the multivariable analysis, a higher rate of treatment with curative intent (time ratio 1·17, 95 per cent c.i. 1·05 to 1·30; P < 0·001) and a higher resection rate (time ratio 1·24, 1·12 to 1·37; P < 0·001) were associated with improved survival after adjustment for relevant confounders.CONCLUSION: Patients diagnosed in counties with higher rates of treatment with curative intent and higher rates of surgery had better survival.

Differences in multidisciplinary cancer conferences of esophageal and gastroesophageal junctional cancer regarding staging, resectability and treatment allocation – a multicenter study
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background: There are differences in esophageal cancer care across different regions in Sweden. According to Swedish national guidelines, all patients diagnosed with these tumors should be individually evaluated by regional multidisciplinary cancer conferences (MCCs) to be recommended best possible treatment. The aim of the study was to investigate differences between the regional MCCs in Sweden regarding clinical staging and recommended treatment.Method: Representatives for all six regional MCCs were invited to contribute with ten retrospective consecutive cases each. After anonymization radiological investigations were presented, along with the original case-specific medical history, anew at all participating regional MCCs. Each MCCs’ clinical Tumor Nodal Metastasis classification (cTNM) and treatment recommendation (curative, palliative or best supportive care) were compared between MCCs as well as with the original assessment. Results: Five regional MCCs joined the study. Out of 50 available cases the majority were assessed anew in addition to the previous original assessment. There was not consensus among the regional MCCs regarding cT-stage in 42 cases (84%), cN-stage in 33 cases (66%), and for cM-stage in 16 cases (32%). Differences in appraisal were not associated with PET-CT availability. The MCCs agreed on treatment recommendations in 26/50 cases (52%). Discussion: The study shows differences, both in assessment of cTNM as well as treatment recommendations at different MCCs. A patient recommended curative treatment by one MCC could be suggested palliative care by another. To achieve more equal care for esophageal cancer patients in Sweden it is essential to increase consensus on cTNM and recommended treatment.

- There are differences in esophageal cancer care across different counties in Sweden. According to national guidelines, all patients should be offered equal care which should be administrated by regional multidisciplinary cancer conferences (MCCs). The aim of the study was to investigate differences between the six regional MCCs in Sweden regarding clinical stageing and recommended treatment.Ten consecutive cases per participating center, 60 cases in total, were planned for inclusion. After anonymization the radiological investigations were presented, along with the original case-specific medical history, anew at the six regional MCCs. Estimation of clinical TNM and treatment allocation (curative, palliative or best supportive care) were compared between MCCs as well as with the original assessment. Interim analysis was performed in April 2022 when ten cases had been presented at five of the six regional MCCs.All available cases were assessed at five MCCs in addition to the previous original assessment (60 assessments). The mean age for the first ten cases was 74.8 years (SD ± 9.8 years). Eight out of ten cases were men. In estimations of T- and N-stage the MCCs agreed in only one out of ten cases. In half of the cases more than three different estimations of N-stage were made. For clinical M-stage there was exact agreement in three cases. In determination of recommended treatment, all five MCCs were in agreement on half of the cases.Preliminary data show striking differences, both in assessment of TNM as well as treatment recommendation at different MCCs. One patient, recommended curative treatment by one MCC could be allocated to palliative care by another. Inclusion is ongoing and further analysis of these differences are warranted to achieve more equal care for esophageal cancer patients in Sweden.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Esophageal cancer is the sixth most common cause of cancer-related death. Choice of surgical approach and individualized treatment is crucial. The aims of this thesis were to evaluate the introduction of minimally invasive esophagectomy (MIE) regarding oncological results and postoperative complications. To investigate radiological differences in pulmonary complications between MIE and open technique by studying computed tomography (CT). To evaluate geographical differences in intention for curative treatment and their association to survival. As well as to further explore these differences by comparing assessments of tumor stage (TNM) and treatment recommendations in anonymized cases at regional multidisciplinary cancer conferences (MCC).A comparison of 51 MIE (21 hybrid and 30 totally minimally invasive) and 65 open resections in 2007-2016, showed an increased lymph node yield in the MIE group, 18 (13–23) vs. 12 (8–16) median (IQR), p<0.001. The result was confirmed in a multivariate regression model (adjusted odds ratio 3.15 [1.11–8.98], p=0.03). Postoperative complications did not differ between the groups.When comparing CT after open esophagectomy (n=20) and MIE (n=20), no ipsilateral differences in the areas of atelectasis or pleural effusion were seen. Nor did the groups differ in the proportion of patients with clinically important atelectasis (dx: 30% vs. 25%, sin: 65% vs. 65%) or pleural effusion (dx: 15% vs. 15%, sin: 65% vs. 45%).A total of 5959 esophageal cancer patients, diagnosed 2006-2015 in Sweden, were identified from the National Register for Esophageal and Gastric Cancer (NREV). In a multivariable analysis, a higher rate of treatment with curative intent (time ratio 1.17 [1.05-1.30], p<0.001) and a higher resection rate (time ratio 1.24 [1.12-1.37], p<0.001) were associated with improved survival.Fifty anonymized esophageal cancer cases were distributed to five expert MCCs. In estimations of T-stage, the MCCs were in total agreement in eight of 50 cases (16%). For N-stage, total agreement was seen in 17 cases (34%) and for clinical M-stage in 34 cases (68%). The MCCs agreed on recommended treatment in 26/50 cases (52%). In conclusion, the introduction of MIE resulted in a larger lymph node yield, without increased risk for complications. No difference in postoperative pleural effusion and atelectasis was seen on computed tomography five days after open esophagectomy compared with MIE. Patients diagnosed in a county with a higher curative intention rate and a higher rate of surgery had better five-year survival and there are differences in assessment of esophageal cancer patients at different MCCs.
