Objective: To analyze the status and number of metabolic and bariatric surgeries (MBS) in China in 2024.
Methods: Surgical volumes, procedure distribution, and workforce scale were estimated through integrated synthesis with multi-source data cross-validation, based on the Chinese Obesity and Metabolic Surgery Database (COMES Database). This study did not include data from the Hong Kong SAR, Macao SAR, and Taiwan region of China.
Results: 190 hospitals were included in this study, covering 29 provinces (autonomous regions and municipalities) and 75 cities, with a total estimated 32 342 cases. It was also estimated that there were 970 hospitals in the country, with 1 430 bariatric surgeons and 800 case managers involved in MBS. The top three most performed MBS were sleeve gastrectomy (SG, 24 443 cases, 75.6%), Roux-en-Y gastric bypass (RYGB, 1 250 cases, 4.7%), one-anastomosis gastric bypass (OAGB, 1 234 cases, 3.8%), and 4 (0.017%) deaths reported.
Conclusions: The number of MBS decreased by 13.2% in 2024. The most performed procedures were SG, RYGB and OAGB. We should leverage the national "Weight Management Year" initiative to develop an integrated multidisciplinary care system for weight management. This requires strengthening standardized training programs, promoting multicenter clinical research, and enhancing international collaborations. Such efforts will advance the discipline’s sustainable development, elevate clinical standards, and expand its global standing.
