Roux-en-Y gastric bypass (RYGB) is an effective treatment for morbid obesity. However, it may lead to diseases of the bilio-pancreatic tract. We evaluated transgastric endoscopic retrograde cholangiopancreatography (ERCP) for managing common biliary tract diseases in patients that underwent RYGB treatment for obesity. This prospective study was conducted between 2003 and 2010 at three medical institutions. We included 23 patients with a mean body mass index of 28.2 kg/m(2) after RYGB treatment. ERCP was performed in all patients to manage biliary tract diseases within 9 to 27 months (mean 16.3 months) of RYGB surgery. The gastrotomy was conducted through the anterior wall of the greater curve of the excluded stomach. A duodenoscope was introduced in the direction of the ostomy to perform the ERCP with sphincterotomy. All patients underwent an ERCP and papillotomy without incident. Ten patients underwent simultaneous cholecystectomy. A total of 17 gallstones were removed. The average gastrotomy duration was 92.69 min; the average hospital stay was 2 days. One patient had mild acute pancreatitis that resolved clinically. There was no mortality. Laparoscopy-assisted transgastric ERCP was feasible and safe for patients after RYGB. The necessary equipment is available in most bariatric surgery centers.
