Abstract:

Objective

To analyze the status and number of metabolic and bariatric surgery (MBS) in China in 2021.

Methods

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 2021; 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. Data from Hong Kong SAR, Macao SAR, and Taiwan region of China were not included in this study.

Results

A total of 180 hospitals or centers participated in this study, covering 29 provinces (autonomous regions and municipalities) and 88 cities, with 23 040 cases. There were 22 331 (96.9%) laparoscopic surgeries included 18 533 (83.0%) sleeve gastrectomy, 1 297 (5.8%) Roux-en-Y gastric bypass, 1 894 (8.5%) sleeve plus surgeries, 507 (2.3%) one-anastomosis gastric bypass / mini gastric bypass, and 93 (0.4%) fundoplication. One (0.004%) open surgery, 58 (0.3%) endoscopic / swallowing technique, 433 (1.9%) robotic-assisted surgery, 217 (0.9%) revisional surgery, and 5 (0.02%) deaths. The estimated total number of MBS was 25 208. There were 164 (91.1%) hospitals with 513 full-time bariatric surgeons and 141 (78.3%) hospitals with 242 full-time case managers. MDT was established in 146 (81.1%) hospitals, and 100 (68.5%) hospitals established a local MBS database.

Conclusions

The number of MBS increased significantly this year. The most popular procedures are laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). The numbers of LSG plus surgery, endoscopic / swallowing techniques, robot-assisted surgery, and revisional surgery are increasing. The numbers of full-time bariatric surgeons and case managers are also growing. Our future priorities will be strengthening the continuing education and training of medical professionals, surgical safety and quality management, long-term follow-up of patients, clinical data integrity, scientific research translation, and local and global academic exchanges.
