Metabolic surgery is one of the effective ways to treat obesity and type 2 diabetes mellitus. Sleeve gastrectomy is widely accepted for its simple operation and exact effect. However, single sleeve gastrectomy offers lower weight loss and diabetes remission rates than gastric bypass procedure, and there are also some problems such as weight regain and diabetes remission rate decrease after operation. Therefore, in recent years, based on sleeve gastrectomy, a variety of additional procedures have been developed to improve the efficacy of sleeve gastrectomy, including single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S), single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy (SG-DJB), single-anastomosis duodenal-jejunal bypass with sleeve gastrectomy (SADJB-SG), sleeve gastrectomy with modified jejunoileal bypass (SG-MJIB), stomach intestinal pylorus sparing (SIPS), sleeve gastrectomy plus side-to-side jejunoileal anastomosis (JI-SG), sleeve gastrectomy with jejunal bypass (SG-JJB), etc. Although some articles have introduced some individual procedures, there is no comprehensive review concerning this category of procedures. Here, the authors summarize these new procedures, so as to provide recommendations for clinical practice.
