title: Laparoscopic exploration versus intraoperative endoscopic sphincterotomy for common bile duct stones: a prospective randomized trial.
abstract: OBJECTIVE
  Laparoscopic cholecystectomy (LC) combined with intraoperative endoscopic sphincterotomy (IOES) was compared to LC with laparoscopic common bile duct exploration (LCBDE) to define the best single-session minimally invasive treatment for cholecystocholedocholithiasis.
  
  
  METHODS
  Between June 2009 and December 2010, patients with gallstones and common bile duct (CBD) stones diagnosed by preoperative ultrasonography and magnetic resonance cholangiopancreatography were randomized to LC-LCBDE or LC-IOES. The primary end point was complete clearance of CBD of stones. The secondary end points were operation time, conversion rate, length of hospital stay, complications and mortality.
  
  
  RESULTS
  Two hundred and twenty-six patients were eligible. They were randomized to LC-LCBDE (n = 115) and LC-IOES (n = 111). There was no statistically significant difference in the success rate of CBD clearance between the two interventions (92% for LC-LCBDE vs. 97.2% for LC-IOES with a p value >0.05). There were no differences between the two groups in terms of surgical time and postoperative length of stay. Pancreatitis and bleeding sphincterotomy were significantly more prevalent in the LC-IOES group, while bile leakage and retained CBD stones were significantly more prevalent in the LC-LCBDE group.
  
  
  CONCLUSIONS
  Both LC-IOES and LC-LCBDE were shown to be safe, effective, minimally invasive treatments for cholecystocholedocholithiasis, but the former option may be preferred when facilities and experience in endoscopic therapy exist.
