Sleeve gastrectomy is currently the most commonly performed bariatric surgery procedure. There remains controversy regarding the intraoperative management of hiatal hernia during sleeve gastrectomy for obesity patients. In China, the mainstream approach is active explora-tion and repair of the hiatal hernia during surgery. Nevertheless, some reports suggest that this may not lead to definitive outcomes and might even exacerbate gastroesophageal reflux symptoms. Based on clinical experience, the authors discuss the current strategies of intraoperative management of hiatal hernia during sleeve gastrectomy, and explore the clinical management strategies for obesity patients with esophageal hiatal hernia undergoing sleeve gastrectomy.

Objective To quantify the association between obesity and erectile dysfunction (ED) risk through a meta-analysis. Methods Following PRISMA guidelines, systematic searches of Chinese and English databases (up to March 2025) were conducted to include observational studies (cohort, cross-sectional, case-control). Adjusted effect sizes (OR and 95% CI) were extracted. Study quality was assessed using the Agency for Healthcare Research and Quality(AHRQ) scale, and a random-effects model was applied to pool effect sizes. Subgroup analyses (geographic region, obesity definitions) and sensitivity analyses were performed to validate robustness. Results Ten studies (n=230 744), including nine cross-sectional studies, were included. The meta-analysis revealed that obesity significantly increased ED risk (random-effects OR=1.80, 95% CI: 1.29-2.51), with high heterogeneity (I2=99.9%). Subgroup analyses indicated stronger associations in USA populations (OR=2.10, 95% CI: 1.23-3.60) than in Chinese populations (OR=1.16, 95% CI: 1.05-1.28). The highest effect size was observed when using BMI≥25 kg/m3 as the obesity threshold (OR=3.05, 95% CI: 2.06-4.51). Sensitivity analyses confirmed robust results (OR: 1.60-1.94 after excluding any single study). Conclusions Obesity is a critical risk factor for ED, with effect strength influenced by geographic region and obesity definitions. Interventions targeting BMI≥30 kg/m2 in Western populations and metabolic risks at BMI≥25 kg/m3 in Asian populations are recommended.

Objective:To establish and assess the quality control and improvement system for metabolic and bariatric surgery in Beijing.Methods:Based on relevant documents from the National Health Commission and the Beijing Municipal Health Commission,and referencing the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) by the American Society for Metabolic and Bariatric Surgery,a quality control system was developed under the Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery. The system incorporated on-site evaluations,data registration,and specialized training. From May to December 2023,on-site assessments were conducted at 21 hospitals in Beijing performing bariatric surgery,evaluating personnel qualifications,infrastructure,clinical workflows,and postoperative follow-up. A quality control database was created to collect real-time surgical data,and training was provided for data entry and professional skills. Assessment results were classified as excellent,qualified,or needing improvement,with rectification suggestions offered and follow-up visits conducted to track progress.Results:All 21 hospitals achieved a 100% compliance rate for surgical indications, 16 (76.2%) met standardized surgical operation criteria,and 14 (66.7%) had standardized postoperative management. However,only 5 (23.8%) achieved a 12-month postoperative follow-up rate of ≥60%,and 4 (19.1%) had established specialized databases. Key challenges included insufficient specialized staffing (19.1%), lack of multidisciplinary collaboration (47.6%), inadequate equipment (57.1%), and low follow-up rates (57.1%). The database collected data from over 2 000 patients across 111 fields. After rectification, specialized database coverage rose to 61.9% (13 hospitals). Multi-level training programs developed backbone physicians and specialized nurses,significantly addressing the shortage of specialized personnel.Conclusion:The quality control system established in this study,through the integration of on-site evaluation,data registration,and specialized training,effectively enhances the standardization of surgical practices and data management capabilities.

Objective:To investigate the safety and efficacy of metabolic surgery in obese and type 2 diabetes patients with viral hepatitis cirrhosis.Methods:The data of 8 patients with viral hepatitis cirrhosis undergoing metabolic surgery at Department of General Surgery ,Beijing Tiantan Hospital, Capital Medical University from Aug 2012 to Dec 2021 were retrospectively analyzed.Results:Among the 8 patients, 2 underwent laparoscopic Roux-en-Y gastric bypass and 6 underwent laparoscopic sleeve gastrectomy. The Child-Pugh classification of all patients before operation was classified as Grade A. The operation process was successful with no complications such as ascites, bleeding , digestive tract and gastric leakage or obstruction during the perioperative period. There was no abnormal liver function and decompensation during the median 2.5 year's (3 month to 8 years) follow-up period. The weight loss after the operation was obvious, when 1 year after operation, percentage of excess weight loss (EWL%)>54.78% and the surgery was also conducive to the control of blood glucose in diabetes patients.Conclusion:Metabolic surgery is safe and feasible for obese and type 2 diabetes patients with viral hepatitis cirrhosis.

Objective:To investigate the clinical effect of laparoscopic sleeve gastrectomy (LSG) in the treatment of obesity with non-alcoholic fatty liver disease (NAFLD).Methods:The clinical data of 115 obese patients with NAFLD who underwent LSG surgery at Beijing Tiantan Hospital were analyzed.Results:LSG was successful in a 115 patients, and the body weight and BMI decreased gradually, and were significantly lower than the preoperative level (all P<0.001). EWL% increased and was 73.1%±30.1% at 12 months after operation. The postoperative triglyceride level decreased and was significantly lower than the preoperative level (all P<0.05). Most patients were complicated with abnormal liver function before surgery, and ALT, AST and GGT levels decreased to the normal range 3 months after surgery (all P<0.05). Albumin level was significantly higher 3 months after operation than before operation ( P<0.001). At 12 months postoperatively, the severity grade of fatty liver on ultrasound was significantly lower than that before surgery ( P<0.001). Conclusion:Laparoscopic sleeve gastrectomy can significantly improve lipid metabolism index, liver function index and fatty liver index in NAFLD patients along with weight loss .

Objective To investigate the effects of gastric bypass on glycometabolism and improvement of islet β cell function and insulin resistance in patients with type 2 diabetes. Methods Eight patients with type 2 diabetes combined with gastric carcinoma who treated with gastric bypass were studied prospectively. Fasting and postprandial plasma glucose levels, fasting and postprandial insulin C-peptide levels, and body mass index (BMI) were measured right before the surgery and at intervals of 1 week, 2 weeks, 1 month and 3 months after the surgery. Glycosylated hemoglobin (HbA1c) levels were measured before and 3 months after the surgery. The outcome of the diabetes after 3 months of the surgery was also monitored. Results Fasting and postprandial plasma glucose levels decreased (P ＜ 0.05) and fasting and postprandial insulin C-peptide levels increased (P ＜ 0.05) after the surgery. HbA1c levels also decreased (P ＜ 0.05) after 3 months of the surgery. There was no significant change of BMI at all intervals after the surgery(P＞ 0.05). All of the 8 patients reached the total effective standard and 6 patients reached the clinical remission standard after 3 months of the surgery. Conclusions It suggests that gastric bypass can significantly lower plasma glucose levels in type 2 diabetes, which does not depend on the loss of weight. The control of plasma glucose by gastric bypass may be due to the improvement of islet β cell function and increasing secretion of endogenous insulin.
