Applying an Anti-reflux Suture in the One Anastomosis Gastric Bypass to Prevent Biliary Reflux: a Long-Term Observational Study

The one anastomosis gastric bypass (OAGB) is an effective treatment to induce sustained weight loss in morbidly obese patients. Concerns remain regarding the development of reflux. aim this study was investigate effect “anti-reflux suture” as anti-reflux modification prevent This a single-center retrospective cohort patients who underwent primary OAGB at Center Obesity North-Netherlands (CON) between January 2015 and December 2016. Reflux defined symptoms acid/bilious regurgitation or pyrosis. consequently asked reported each follow-up visit. Outcomes with suture were compared those without. In 414 (59%) 703 included patients, applied. Follow-up 3 years 74%. incidence reflux did not differ without (57 versus 56%, respectively; P = 0.9). presence significantly associated lower conversion Roux-en-Y (RYGB) for (OR 0.56, 95%CI 0.34–0.91). Patients preoperatively diagnosed gastroesophageal disease (GERD) 5.2 times more likely need RYGB (95%CI 2.7–10.1). preoperative GERD should be weighted heavily decision perform major risk factor surgery due might valuable addition procedure because it results fewer surgeries
