Analysis of the layout and proportion of classic and innovative surgical procedures of bariatric and metabolic surgery throughout the world, the sleeve gastrectomy is beco-ming the most accepted and respected surgical procedure with its increasingly prominent advan-tages, and its operation number has even exceeded the "gold standard" surgery of the roux-en-Y gastric bypass. This trend is even more pronounced in China. With a small number of physicians lacking experience in gastrointestinal surgery and more and more young physicians joining in the field of bariatric and metabolic surgery, operation related complications and the consequences of insufficient perioperative management experience have occurred successively in clinical practice, such as gastrointestinal leakage, bleeding, lumen and anastomotic stenosis, internal hernia and obstruction, venous thromboembolism, etc. Bariatric and metabolic surgery is a branch of gastro-intestinal surgery, and physicians in the field should have the ability to prevent, predict and manage short- and long-term complications after surgery. The authors believe that through the comprehen-sive evaluation of laboratory indexes, patient signs and related examinations, physicians should have the basic qualities of decisively choosing the surgical timing, choosing the right decision-making, and taking effective measures.
