Conversion of one anastomosis gastric bypass (OAGB) to roux-en-Y gastric bypass (RYGB) for biliary reflux resistant to medical treatment: lessons learned from a retrospective series of 2780 consecutive patients undergoing OAGB
Biliary reflux resistant to medical treatment has an incidence of 0.6-10% after one anastomosis gastric bypass (OAGB) and may be a reason for revisional surgery. The aim of this study is to report the results of a single-institution series of patients who underwent conversion from OAGB to Roux-en-Y gastric bypass (RYGB) for biliary reflux.
