Reflux and bariatric surgery: a review of pre-operative assessment and post-operative approach

Abstract

Bariatric surgery is the cornerstone of treatment for severe obesity. In evaluating patients for such procedures, surgeons must be aware of the potential complications, including post-operative gastroesophageal reflux disorder (GERD). This review article outlines the current literature regarding GERD prior to and after bariatric surgery. It aims to establish a framework for evaluating and managing GERD in both the pre- and post-operative setting for common bariatric procedures such as the sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric band, duodenal switch type procedures as well as one-anastomosis gastric bypass. This review also outlines the latest recommendations from major international bariatric societies for screening prior to surgery, the incidence of GERD after each respective procedure and a summary of current trends in the management of post-operative GERD after bariatric surgery.
