Chinese expert consensus on precision obesity metabolic surgery (2022 edition)

With the increasing prevalence of obesity and the popularity of bariatric surgery, more and more patients with obesity are undergoing bariatric surgery. "Precision Medicine" is a new generation of medical concepts. Introduce the concept of "precision medicine" into precision bariatric and metabolic surgery, in order to optimize and integrate modern surgical theory and technology with traditional surgical methods under the requirements of high precision and high efficiency standards, so as to achieve minimal trauma and invasion, maximum organ protection, minimum medical cost and best weight loss effect. Chinese Society for Metabolic and Bariatric Surgery (CSMBS) organized some domestic experts to conduct four relevant problem‑oriented and 36 clinical practical problems, including precise preoperative assessment, precise perioperative management, precise surgical operation, and precise postoperative management. Based on domestic and foreign literature evidence and combined with Chinese conditions and clinical experience, CSMBS has formulated a Chinese expert consensus on precision obesity metabolic surgery, aiming to provide guidance for the clinical practice of precision obesity metabolic surgery in my country.
