Laparoscopic sleeve gastrectomy (LSG) is an effective and lasting method for treating obesity, type 2 diabetes and other obesity related metabolic diseases. The symmetrical three-port LSG has been proven to be a simple, safe, and effective surgical procedure. However, China still lacks standardized surgical operation guidelines for this method. This guideline provides a detailed description of the various steps and key details of the symmetrical three-port LSG, aiming to standardize and normalize the symmetrical three-port LSG in the bariatric and metabolic field in China, and to provide standardized surgical procedures for clinical surgeons in this field.
A lot of evidence-based medical evidence has shown that laparoscopic Roux-en-Y gastric bypass (LRYGB) is a durable and effective method for obesity and diabetes, and can significantly improve a series of obesity-related metabolic complications. This guideline provides a detailed description of the main operating steps and technical points of the symmetric three-port LRYGB, including posture layout, trocar position selection, liver suspension, gauze exposure, production of small gastric sacs, gastrojejunal anastomosis and production of biliary pancreatic branches, entero-enteric side to side anastomosis, closure of gastrointestinal anastomosis and mesenteric hiatus, greater omentum coverage, and closure of incisions. The purpose is to standardize the operating process of the symmetrical three hole method of LRYGB, providing standardized surgical operation references for clinical doctors in the field of obesity metabolic surgery.
