Bariatric surgery is the only effective procedure that provides long-term sustained weight loss. Sleeve gastrectomy (SG) has emerged over the last few years to be an ideal bariatric procedure because it has several advantages compared to more complex bariatric procedures, including avoiding an intestinal bypass. However, several published follow-up studies report an increased rate of gastroesophageal reflux (GERD) after a SG. GERD is described as either de novo or as being caused by aggravation of preexisting symptoms. However, the literature on this topic is ambivalent despite the potentially increased rate of GERDs that may occur after this common bariatric procedure. This article reviews the mechanisms responsible for GERD in obese subjects as well as the results after a SG with respect to GERD. Future directions for clinical research are discussed along with the current surgical options for morbidly obese patients with GERD and undergoing bariatric surgery.
Core tip: Bariatric surgery is the only effective means to sustain weight loss. Sleeve gastrectomy (SG) has become popular because of its advantages over more complex bariatric procedures. However, an increased rate of gastroesophageal reflux (GERD) has been reported after SG that is either de novo or is caused by aggravation of preexisting symptoms. The literature is ambivalent about the implications for increased rates of GERD after SG. This article reviews the mechanisms of GERD in obese subjects, and the results from SG with respect to GERD. Future directions are discussed along with current surgical options for obese patients with GERD and undergoing bariatric surgery.
