title: Laparoscopic choledochoduodenostomy as an alternate treatment for common bile duct stones after Roux-en-Y gastric bypass.
abstract: BACKGROUND
  After Roux-en-Y gastric bypass (RYGB), the new gastrointestinal configuration does not permit easy endoscopic access to the biliary system in the standard fashion. Common bile duct (CBD) stones have proved to be a challenge for both the surgeon and the endoscopist in this setting. We shall review our experience with laparoscopic choledochoduodenostomy as a treatment of choledocholithiasis after gastric bypass.
  
  
  METHODS
  Between January 2000 and July 2012, 3115 patients underwent RYGB at our institution. Patients were included if they had postoperative CBD stones regardless of previous cholecystectomy. Treatment modality was laparoscopic choledochoduodenostomy. A retrospective chart review of a prospectively collected data was completed, noting the outcomes and complications of the procedure.
  
  
  RESULTS
  Of 3115 patients, 11 patients were included in this study. There were 8 female and 3 male patients with a mean age of 50.5 ± 10.9 (range, 34-66) years. The average time between primary RYGB and choledochoduodenostomy was 39.7 ± 33.8 (range 8-113) months. The average body mass index at primary surgery was 48.2 ± 8.1 (range 38.4-67.4) kg/m(2) and at choledochoduodenostomy was 29.5 ± 6.8 (range 22.7-46.9) kg/m(2). One patient had bile leak that was managed with drain. All patients had resolution of symptoms at a mean follow-up of 24.8 ± 26.9 (range 2-84) months.
  
  
  CONCLUSIONS
  This small case series suggests that, in experienced hands, laparoscopic choledochoduodenostomy is an option for safe and effective treatment of choledocholithiasis after gastric bypass.
