统计分析2022年中国肥胖代谢外科手术开展情况。

基于中国肥胖代谢外科数据库（COMES Database），精确统计分析2022年1月1日至2022年12月31日在中国大陆开展的减重手术种类和例数、死亡病例数，以及专职人员、多学科团队（MDT）及院内数据库建设情况；并以此为基础，推算全国减重手术实际总数量。结果按往年的报告模式作为标准模版进行汇报。本次统计未含中国香港、中国澳门及中国台湾地区的数据。

全国共191家医院或减重中心参与本次统计，地域涵盖29个省（自治区、直辖市），100个城市，录得总手术量27 001例。其中腹腔镜手术26 474例（98.0%），包括袖状胃切除术23 232例（87.8%）、Roux-en-Y胃旁路术896例（3.4%）、袖状胃联合手术1 568例（5.9%）、单吻合口胃旁路/迷你胃旁路术760例（2.9%）、胃底折叠术11例（0.042%）等。开腹手术1例（0.004%），内镜减重手术/可吞咽技术15例（0.1%），机器人辅助手术283例（1.0%），修正手术228例（0.8%）。死亡3例（0.011%）。推算全国减重手术实际总数量约为30 071例。统计到共181家（94.8%）医院有专职减重外科医生（共597位），158家（82.7%）医院有专职减重个案管理师（共259位）。有162家（84.8%）医院成立了MDT，134家（70.2%）医院建立了院内减重手术数据库。

本年度全国减重手术量持续增加，主流手术仍是腹腔镜袖状胃切除术（LSG）和腹腔镜Roux-en-Y胃旁路术（LRYGB）；LSG联合手术、内镜手术/可吞咽技术、机器人辅助手术等数量较去年稍下降，但修正手术仍轻微上升。专职的减重外科医生及个案管理师人数持续增加。坚持规范化管理，完善医护培训体系及全国数据库系统，加强患者的长期随访，对新兴手术技术深入探索，开展全国多中心研究合作，继续推动行业发展及质量提升。

To analyze the status and number of metabolic and bariatric surgery (MBS) in China in 2022.

Based on the Chinese Obesity and Metabolic Surgery Database (COMES Database), we analyzed the types and numbers of MBS and the mortality rate between January 1 and December 31 in 2022; and the numbers of bariatric surgeons and case managers, multidisciplinary team (MDT), and the database of each hospital. We also attempted to estimate the actual number of MBS in the country. The results were presented in the format of the previous annual reports. This study did not include data from the Hong Kong SAR, Macao SAR, and Taiwan region of China.

191 hospitals or centers participated in this study, covering 29 provinces (autonomous regions and municipalities) and 100 cities, with 27 001 cases. There were 26 474 (98.0%) laparoscopic surgeries, including 23 232 (87.8%) sleeve gastrectomy, 896 (3.4%) Roux-en-Y gastric bypass, 1 568 (5.9%) sleeve plus surgeries, 760 (2.9%) one-anastomosis gastric bypass / mini gastric bypass, and 11 (0.042%) fundoplication. One (0.004%) open surgery, 15 (0.1%) endoscopic / swallowing technique cases, 283 (1.0%) robotic-assisted surgery, 228 (0.8%) revisional surgery, and 3 (0.011%) deaths. The estimated total number of MBS was 30 071. There were 181 (94.8%) hospitals with 597 full-time bariatric surgeons and 158 (82.7%) hospitals with 259 full-time case managers. MDT was established in 162 (84.8%) hospitals, and 134 (70.2%) hospitals established a local MBS database.

The number of MBS has increased significantly in 2022. The most popular procedures were still laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). The numbers of LSG combined surgery, endoscopic surgery/swallowing technique and robot-assisted surgery decreased slightly compared with last year, but the revisional surgery still increased slightly. The number of full-time bariatric surgeons and case managers continues to grow. Adhere to the standardized management, improve the education and training system and the national database, strengthen the long-term follow-up of patients, in-depth exploration of emerging technologies, carry out national multi-center studies, and continue to promote the development of the field and quality improvement.
