title: Robot-Assisted Choledochoduodenostomy: A Safe and Reproducible Procedure for Benign Common Bile Duct Obstruction.
abstract: BACKGROUND
  Choledochoduodenostomy (CD) is an option for treating choledocholithiasis and benign biliary obstruction after failure of endoscopic treatment. Nevertheless, this procedure is rarely performed using a mini-invasive approach because of its technical complexity. Robotic assistance could be a safer approach to overcome such technical issues.
  
  
  METHODS
  All consecutive patients who underwent a robot-assisted CD for benign biliary obstruction were included.
  
  
  RESULTS
  Between 2012 and 2016, 12 patients were operated on, 7 of whom had a body mass index over 25 (58%) and 7 were ASA class 3 (58%). The median age was 73 years (range 49-93). Median operative time was 140 min (range 105-208) and median blood loss was 90 mL (range 5-500). One patient presented with cholangitis 1 month after surgery (treated medically, Clavien-Dindo grade 2). Median length of stay was 7 days (range 3-8). None of the patients experienced severe morbidity after a median follow-up of 15 months.
  
  
  CONCLUSIONS
  Robot-assisted CD is safe and feasible in benign biliary obstruction.
