Abstract
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is currently the most commonly performed bariatric procedure worldwide. However, the incidence of gastroesophageal reflux disease (GERD) after LSG is high. OBJECTIVES: The aim of this systematic review was to identify the optimal surgical strategy for treating GERD after LSG. SETTING: West China Hospital, Sichuan University, Chengdu, China. METHODS: A systematic literature search was performed to identify studies on surgical treatments for GERD after LSG. The effectiveness and safety profile of surgical management on GERD after LSG were analyzed. RESULTS: A total of 40 articles enrolling 2049 patients were included in this review. Surgical strategies to prevent GERD after LSG were mainly of 2 types: concomitant LSG + antireflux procedures (hiatal hernia repair or fundoplication) and secondary procedures (conversion to Roux-en-Y gastric bypass [RYGB] or repeat sleeve gastrectomy). The short-term remission or improvement rate of GERD was 34.6%-100% after concomitant LSG + antireflux procedures. The postoperative complication rate was the same (3.0%) for both LSG + antireflux procedures and LSG alone. The remission or improvement rate of GERD was 57.1%-100% after conversion to RYGB and 100% after repeat sleeve gastrectomy. CONCLUSIONS: The effectiveness and safety profile of concomitant LSG + antireflux procedures is uncertain. However, secondary operations after LSG, such as conversion to RYGB, appear to provide good results. The data overall are heterogeneous, with imprecise methods of documenting and defining GERD complicating LSG. More cohort studies or RCT studies of high quality with long-term follow-up are needed in the future.
