Abstract: Sleeve gastrectomy (SG), as the most widely performed metabolic and bariatric surgery, has significant effects, but SG is associated with a high incidence of postoperative gastroesophageal reflux disease (GERD). The sleeve gastrectomy combined with the transit bipartition (SG-TB) procedure, as an SG Plus surgery, reduces the gastric pressure and the retention time of food in the stomach by adding a channel based on SG, effectively reducing the risk of GERD and maintaining a good weight loss metabolic effect. However, the mechanism by which SG-TB prevents GERD after SG has not been fully clarified, and more basic and clinical studies are still needed to illustrate it.

摘要： 胃袖状切除术（SG）作为目前开展最为广泛的减重代谢手术，虽然效果显著，但术后胃食管反流病（GERD）的发生率较高。胃袖状切除联合双通路术（SG-TB）作为SG联合手术，通过在SG基础上增加一个通道，降低胃内压力，减少食物在胃内滞留时间，从而有效降低GERD的发生风险，同时其减重代谢效果也较好。但是，SG-TB预防SG术后GERD的机制尚未完全明确，仍需要开展更多的基础和临床研究以明确。
