Metabolic and bariatric surgery in China has entered a period of rapid development. In addition to sleeve gastrectomy and Roux-en-Y gastric bypass，there are also a variety of surgical procedures emerging in clinical practice，including one anastomotic gastric bypass，biliopancreatic diversion with duodenal switch，single anastomotic duodenal-ileal bypass with sleeve gastrectomy，duodenojejunal bypass with sleeve gastrectomy，jejunal-jejunal bypass with sleeve gastrectomy，gastrojejunal transit bipartition with sleeve gastrectomy，etc. For surgeons who have not experienced systematic theoretical knowledge and clinical practice training，and who have recently started metabolic and bariatric surgery practice，the choice of surgical procedures often creates confusion. The principle is to identify the surgical methods that are strongly recommended，cautiously recommended，not recommended and investigational. According to surgon’s own capability，team capability，availability of facility and equipment，as well as patients' comorbidities and expectations，the mode of shared decision-making between surgeons and patients should be adopted to objectively select an appropriate surgical procedure.
