Reflux After Sleeve Gastrectomy: An Update

Background: Modifications of gastric anatomy, function, and of the esophagogastric junction secondary to sleeve gastrectomy (SG) can worsen the symptoms of gastroesophageal reflux disease (GERD). Its late diagnosis and poor treatment can lead to serious complications. In recent years, attempts have been made to optimize preoperative studies and improve surgical techniques to prevent this problem. The aim of this study was to update on the presence of GERD and their symptoms post-SG. Methods: A literature review of articles based on randomized clinical trials on the presence of GERD after SG was carried out, in a period of 10 years. Results: A result of 336 articles was obtained, of which 327 were discarded and 9 were included. The variables of GERD post-SG were analyzed according to their symptoms ("improved," "worsened," and "unchanged"), "remission," or appearance "de novo." Conclusion: GERD is a frequently associated pathology in obese patients. Several authors reported that symptoms worsen after SG, and has been diagnosed de novo. The application of exhaustive preoperative studies and a correct surgical technique could reduce its incidence.
