Obesity is related with higher incidence of gastroesophageal reflux disease. Antireflux surgery has inadequate results when associated with obesity, due to migration and/or subsequent disruption of antireflux wrap. Gastric bypass, meanwhile, provides good control of gastroesophageal reflux.
To evaluate the technical difficulty in performing gastric bypass in patients previously submitted to antireflux surgery, and its effectiveness in controlling gastroesophageal reflux.
Literature review was conducted between July to October 2016 in Medline database, using the following search strategy: (“Gastric bypass” OR “Roux-en-Y”) AND (“Fundoplication” OR “Nissen ‘) AND (“Reoperation” OR “Reoperative” OR “Revisional” OR “Revision” OR “Complications”).
Were initially classified 102 articles; from them at the end only six were selected by exclusion criteria. A total of 121 patients were included, 68 women. The mean preoperative body mass index was 37.17 kg/m² and age of 52.60 years. Laparoscopic Nissen fundoplication was the main prior antireflux surgery (70.58%). The most common findings on esophagogastroduodenoscopy were esophagitis (n=7) and Barrett’s esophagus (n=6); the most common early complication was gastric perforation (n=7), and most common late complication was stricture of gastrojejunostomy (n=9). Laparoscopic gastric bypass was performed in 99 patients, with an average time of 331 min. Most patients had complete remission of symptoms and efficient excess weight loss.
Although technically more difficult, with higher incidence of complications, gastric bypass is a safe and effective option for controlling gastroesophageal reflux in obese patients previously submitted to antireflux surgery, with the added benefit of excess weight loss.
