Obesity is a major global public health challenge and a leading cause of multiple metabolic disorders,including hypertension and diabetes.In China,more than half of the adult population is overweight or obese.While anti-obesity pharmacotherapies(such as GLP-1 receptor agonists)and bariatric surgery have both advanced rapidly,strategies for integrating these two modalities remain unclear.In particular,controversies persist regarding surgical eligibility after drug discontinuation,and standardized clinical guidelines are lacking.In July 2025,the International Federation for the Surgery of Obesity and Metabolic Disorders released the world's first statement focusing on"metabolic bariatric surgery after pharmacotherapy-induced weight loss",which emphasizes the chronic disease model of obesity management and clarifies the synergistic relationship between pharmacotherapy and surgery.This article interprets the statement from the perspectives of treatment strategies,surgical eligibility,and drug-surgery coordination,aiming to provide evidence-based reference for clinicians and to promote standardized,integrated obesity management.

Background and Aims:Gastroesophageal reflux disease(GERD)is a common complication following sleeve gastrectomy(SG),particularly in patients with concomitant hiatal hernia,where symptoms tend to be more persistent and refractory,significantly impairing postoperative quality of life.This study aimed to evaluate the efficacy of laparoscopic hiatal hernia repair combined with gastroesophageal fixation in SG patients with severe GERD and hiatal hernia,providing clinical reference for revisional surgical strategies.Methods:The clinical data of 9 patients with severe GERD after SG who underwent laparoscopic hiatal hernia repair and gastroesophageal fixation at Huashan Hospital,Fudan University,between January 2023 and June 2024 were retrospectively analyzed.GerdQ scores,proportion of endoscopically confirmed reflux esophagitis,and proton pump inhibitor(PPI)usage were compared before and after surgery.Surgical parameters and follow-up outcomes were also recorded.Results:All patients successfully completed the surgery without major intraoperative complications,and the mean postoperative hospital stay was 5.22 d.After a mean follow-up period of 15.27 months,the GerdQ score significantly decreased from 11.67±2.00 to 7.22±1.48.The proportion of patients with GerdQ score≥8 decreased from 100.00％to 44.44％,and the rate of endoscopically confirmed GERD dropped from 88.89％to 11.11％;PPI use also significantly declined,with all differences reaching statistical significance(all P＜0.05).Conclusion:Laparoscopic hiatal hernia repair combined with gastroesophageal fixation can effectively alleviate reflux symptoms in SG patients with coexisting hiatal hernia,demonstrating favorable short-term efficacy and high safety.This approach may be a preferable surgical option for selected patients.

Objective To evaluate the feasibility,safety and efficacy of three-port laparoscopic sleeve gastrectomy(LSG).Methods Clinical data of 130 patients with obesity who underwent LSG from April 2020 to January 2021 and completed follow-up in time were analyzed retrospectively.All patients were divided into two groups as surgical method,there were 52 cases in three-port group and 78 cases in four-port group.Perioperative indicators and improvement of obesity in two groups were compared.Results All procedures were performed via LSG.Compared with four-port group,the mean operative time of three-port group was shorter[(88.35±22.64)min vs.(98.29±26.25)min,P=0.027].There were no significant differences in amount of bleeding intraoperative,postoperative pain,postoperative drainage,hospital stay after operation,postoperative complication rate and weight loss 6 months and 2 years after surgery(P>0.05).Conclusions Under the premise of no increase in surgical complications and operative time,three-port LSG can reduce the number and size of surgical scars,which is conducive to skin beauty,and obtain the same weight loss effect as four-port LSG,and can be used as a routine operation for sleeve gastrectomy.

Bariatric surgery is the most effective treatment for obesity and its comorbidities, but mechanisms of bariatric surgery remain unknown. In addition to volume restriction and malabsorption, gut hormones, bile acids, adipokines, intestinal microbiome and central nervous system may be the potential mechanisms.
