Comparison of the efficacy and safety of sleeve gastrectomy plus procedures and gastric bypass

Bariatric and metabolic surgery is an effective treatment for obesity and its associated diseases. Gastric bypass has been the gold standard surgery, but now sleeve gastrectomy has become the most commonly used procedure, both procedures have certain disadvantages. In recent years, on the basis of sleeve gastrectomy, a variety of derivative procedures have been developed to improve the efficacy of sleeve gastrectomy. They mainly include sleeve gastrectomy with gastric banding, sleeve gastrectomy with jejunal bypass, sleeve gastrectomy with duodenal-jejunal bypass, single‑anastomosis duodeno‑ileal bypass with sleeve gastrectomy, stomach intestinal pylorus sparing and single‑anastomosis duodenal‑jejunal bypass with sleeve gastrectomy. The authors summarize the efficacy and safely of these new operations from sleeve gastrectomy and gastric bypass in order to provide certain references for clinical practice.
