- Background: Revisional gastric bypass (R-RYGB) surgery is utilized for the management of inadequate weight loss or weight regain observed after some cases of bariatric surgeries. Data on the mid-term effectiveness of primary gastric bypass (P-RYGB) compared to R-RYGB (e.g., post sleeve gastrectomy or gastric banding) are controversial. Methods: Retrospective chart review of all patients who received P-RYGB and R-RYGB (January 2011 - June 2015) at our center. One hundred and twenty patients who underwent P-RYGB and 34 R-RYGB who completed 18 months follow-up were included. We compared the effectiveness of P-RYGB with R-RYGB by assessing four anthropometric, two glycemic, and four lipid parameters, as well as the control of type 2 diabetes (T2DM), hypertension and dyslipidemia in terms of remission, improvement, persistence, relapse and de novo. The current study also assessed mortality and complications rates. Results: There were no significant differences in the baseline characteristics of patients who received P-RYGB with those who received R-RYGB in terms of age, gender and preoperative BMI. However, at 18 months: a) Patients who received P-RYGB had lower mean weight (P = 0.001) and BMI (P <0.001), reflected by a higher mean delta BMI (P = 0.02), TWL%(P <0.0001) and EWL%(P < 0.0001); b) No differences were observed between the two patients groups in terms of glycemic parameters, lipid profiles, and control of T2DM, hypertension, and dyslipidemia; and, c) No deaths were reported among both patients groups, and complication rates were comparable. Conclusion: Although R-RYGB effectively addressed inadequate weight loss, weight regain and recurrence of comorbidities after restrictive bariatric surgery, R-RYGB resulted in inferior weight loss compared to P-RYGB. There were no significant differences between the two procedures in terms of their clinical control of T2DM, hypertension and dyslipidemia. Both procedures exhibited comparable complication rates.

- Obesity is one of the major health problems of the world, and one of the most common surgical treatments is the Roux-en-Y gastric bypass surgery. This can however lead to problems with postprandial hypoglycemia, but sometimes, the meal test does not render any signs of hypoglycemia. Here, 3 cases are presented with postprandial normoglycemic hypokalemia.

- Nonalcoholic fatty liver disease (NAFLD) is increasingly being linked to obesity. Although laparoscopic sleeve gastrectomy (LSG) is effective for weight loss that can ultimately resolve NAFLD, an initial transient deterioration of liver functions could be observed during the first few months post-operatively, after which a subsequent improvement of the liver functions might occur. Rapid weight loss, nutritional deficiencies, and protein malnutrition can all contribute to hepatic dysfunction and can affect the metabolism of medications such as acetaminophen leading to more insult to a compromised liver. We report acute liver failure after LSG associated with protein calorie malnutrition, multiple nutritional deficiencies in addition to concomitant use of therapeutic doses of acetaminophen. Treatment with N-acetylcysteine, and replacement of deficient multivitamins and trace elements resulted in significant improvement in liver functions.

- Background: Laparoscopic sleeve gastrectomy (LSG) as a primary bariatric procedure has gained increasing popularity world-wide. However, controversies still exist regarding several operative aspects, such as the optimal diameter of thesleeve and the optimal distance from the pylorus to the edge of the resection line, and whether these aspects haveeffects on weight-loss results and the risk to develop postoperative complications.Objective: The aim of this study was to compare weight-loss results and the incidence of postoperative complications betweensleeve with different diameters measured in bougie size and with different distances from the pylorus to the edge ofthe resection line measured in centimeter.Setting: Nationwide registry-based study.Method: This study is an analysis of sleeve gastrectomy performed in Sweden between 2012 and 2019. Data were collectedfrom Scandinavian Obesity Surgery Registry (SOReg). Patients with bougie size 30-32 and 35-36 and patients withdistance from pylorus 1-4 cm, 5 cm, 6-8 cm were identified and compared regarding weight-loss results and the riskto develop postoperative complications.Results: 9,360 patients were included. Follow-up rate was 96% at day 30, 78.8% at one year and 50% at two years. Bothbougie size 30-32 compared to 35-36 and distance from the pylorus 1-4 cm compared to 5 cm were associated withsignificant higher weight-loss at one and two years. No difference in the risk for early or late complications was seenbetween bougie size groups 30-32 and 35-36. Resection starting 1-4 cm from the pylorus compared to 5 cm was as-sociated with higher risk for overall early postoperative complications (OR 1.46 (1.17-1.82, P=.001)), but there wasno significant difference in the risk to develop late complication at 1 and 2 years. No difference in the leak rate andin the risk to develop stricture was seen between different Bougie sizes, nor distances from the Pylorus.Conclusion: Using a smaller Bougie size and starting the resection closer to the pylorus was associated with better maximumweight-loss. Closer resection to the Pylorus, but not Bougie size was associated with increased risk for early postop-erative complications after sleeve gastrectomy.

- Introduction Sleeve gastrectomy (SG) is an effective treatment for obesity in adolescents. The underlying weight loss mechanism may impact the peripheral and central gustatory system along with reward circuits in the brain. This study aims to assess changes in appetitive behavior in short-, medium-, and long-term follow-up. Methods In this prospective observational study, a total of 8 adolescents with obesity who underwent SG and 9 comparator unoperated participants were studied. Appetitive behaviour towards fat and sweet taste stimuli was assessed using the Progressive Ratio Task (PRT) over a 6 year period. Results Mean body mass index (BMI) of the surgical patients dropped from 51.5 +/- 2.8 kg/m(2) to 31.4 +/- 1.9 and 30.9 +/- 2.3 kg/m(2) at 1 and 6 years follow-up, respectively. (p < 0.001). The median (interquartile range) total rewards earned during the PRT was 6 (5-7) pre-surgery, 5 (3-6) after one year and 4 (2-4) after six years from surgery (p = 0.007). Conclusion SG reduced appetitive behaviour at 1 year with maintained the benefit over 6 years as measured by the progressive ratio task.

- BACKGROUND: Abdominal pain after laparoscopic Roux-en-Y gastric bypass (LRYGB) is a common and unwanted complication that typically leads to further exploration through radiology. Concerns have been raised regarding the consequences of this radiation exposure and its correlation with the lifetime risk of cancer. The aim of this study was to evaluate the differences in computed tomography (CT) use between LRYGB patients with open and closed mesenteric defects and to assess the radiological findings and radiation doses.METHODS: This subgroup analysis included 300 patients randomized to either closure (n = 150) or nonclosure (n = 150) of mesenteric defects during LRYGB. The total number of CT scans performed due to abdominal pain in the first 5 postoperative years was recorded together with the radiological findings and radiation doses.RESULTS: A total of 132 patients (44%) underwent 281 abdominal CT scans, including 133 scans for 67 patients with open mesenteric defects (45%) and 148 scans for 65 patients with closed mesenteric defects (43%). Radiological findings consistent with small bowel obstruction or internal hernia were found in 31 (23%) of the scans for patients with open defects and in 18 (12%) of the scans for patients with closed defects (p = 0.014). The other pathological and radiological findings were infrequent and not significantly different between groups. At the 5-year follow-up, the total radiation dose was 82,400 mGy cm in the nonclosure group and 85,800 mGy cm in the closure group.CONCLUSION: Closure of mesenteric defects did not influence the use of CT to assess abdominal pain.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This IFSO survey aims to describe the current trends of metabolic and bariatric surgery (MBS) reporting on the number and types of surgical and endoluminal procedures performed in 2020 and 2021, in the world and within each IFSO chapter.Methods: All national societies belonging to IFSO were asked to complete the survey form. The number and types of procedures performed (surgical and endoluminal interventions) from 2020 to 2021 were documented. A special section focused on the impact of COVID-19, the existence of national protocols for MBS, the use of telemedicine, and any mortality related to MBS. A trend analysis of the data, both worldwide and within each IFSO chapter, was also performed for the period between 2018 and 2021.Results: Fifty-seven of the 74 (77%) IFSO national societies submitted the survey. Twenty-four of the 57 (42.1%) reported data from their national registries. The total number of surgical and endoluminal procedures performed in 2020 was 507,806 and in 2021 was 598,834. Sleeve gastrectomy (SG) remained the most performed bariatric procedure. Thirty national societies (52%) had regional protocols for MBS during COVID-19, 61.4% supported the use of telemedicine, and only 47.3% collected data on mortality after MBS in 2020. These percentages did not significantly change in 2021 (p > 0.05).Conclusions: The number of MBS markedly decreased worldwide during 2020. Although there was a positive trend in 2021, it did not reach the values obtained before the COVID-19 pandemic. SG continued to be the most performed operation. Adjustable gastric banding (AGB) continues to decrease worldwide.

- Background: Gastric bypass (GBP) is a surgical method with good evidence of sustainable weight loss, reduced obesity-related comorbidities, and improved health-related quality of life (HRQoL). However, long-term data post-GBP is scarce on HRQoL related to other factors than weight loss, such as impact of socio-economic, age, and gender. Aim: To investigate long-term HRQoL in GBP patients. Methods: The study was conducted as a cross-sectional study covering 3 to 9 years post-GBP measuring HRQoL using RAND-36. Association to weight loss, time since surgery, gender, educational level, occupation, and age was analyzed. The participants were included on the basis that they had received a GBP that was performed by Region Skåne, the southernmost administrative healthcare region in Sweden. Recruitment to the study was by mail invitation for an online survey. Results: Of the total population of 5310 persons receiving the questionnaire, 1339 of the 1372 responders fulfilled the inclusion criteria. Those with low educational level, unemployed, persons on sick leave or disability support, and those with less weight loss reported the lowest HRQoL. The longer time since surgery, the lower the HRQoL. Conclusion: Less weight loss, longer time since GBP, lower educational level, and lower degree of employment all affect HRQoL negatively after GBP surgery.
