Summary

Obese patients exhibit considerable heterogeneity and complex comorbidities, making long-term effective management challenging with single therapies. While bariatric surgery remains the most effective weight-loss intervention, postoperative weight regain and metabolic deterioration require attention. GLP-1 RAs offer distinct advantages for weight and metabolic improvement, and their combined application with surgery may yield synergistic benefits.

Given the lack of multi-regional validation in China's diverse population, this multicenter study aims to confirm the real-world effectiveness and generalizability of bariatric surgery plus GLP-1RA across distinct regional cohorts.

COMBINATION_PRODUCT

BS-GLP1RA group

1.Basic Treatment Measures Within 0-30 days after sleeve gastrectomy, all patients received very low-calorie enteral nutrition powder (100 kcal/day). From 30 to 90 days post-surgery, a low-energy diet (400 kcal/day) was provided. Beyond 90 days post-surgery, a calorie-restricted diet was implemented (1,500 kcal/day for men and 1,200 kcal/day for women). 2.In addition to laparoscopic sleeve gastrectomy and postoperative basic nutritional counseling,the intervention group received subcutaneous semaglutide injections from 1 to 6 months postoperatively.The specific protocol was as follows:In the intervention group, semaglutide treatment was initiated at 1 month after LSG. The starting dose was 0.25 mg per week and was subsequently titrated up based on individual patient response to a maximum maintenance dose of 2.4 mg per week. The treatment continued until the completion of the 6-month postoperative period.
