With the development of bariatric and metabolic surgery, hospitals at different levels across the country have successively carried out bariatric metabolic surgery, in which laparoscopic sleeve gastrectomy is the most popular. Problems such as postoperative complications and weight regain are increasing due to irregular surgical opera-tions. Combining with their own experience and the characteristics of medical center, the authors summarize the operation details of laparoscopic sleeve gastrectomy in order to further standardize the operation of laparoscopic sleeve gastrectomy and reduce the incidence of postoperative complications.
