Abstract

Gastroesophageal reflux is one of the most common gastrointestinal disorders worldwide and is associated with central obesity. While bariatric surgery is the most effective means of achieving sustainable weight loss and should alleviate reflux, reflux can develop or worsen following bariatric surgery. We reviewed the available literature to summarize the potential pathophysiological mechanisms that can explain reflux outcomes following the 3 most common bariatric surgeries: laparoscopic adjustable gastric banding (LABG), laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (RYGB). Overall, LABG and LSG have been shown to predispose to reflux while RYGB is associated with improvement of GERD.
