ABSTRACT Introduction: Common bile duct (CBD) stone is a common clinical situation, especially in Asia area. Laparotomy and laparoscopic surgical procedure are often used for treatment. This study compares outcomes of different surgical procedures treating for the disease. Methods/design: This is a prospective, randomized, controlled multicenter trial with three treatment arms. One group underwent laparoscopic cholecystectomy (LC) + laparoscopic CBD exploration (LCBDE) + intraoperative endoscopic nasobiliary drainage ENBD + primary closure of CBD. The other underwent preoperative endoscopic retrograde cholangiopancreatography (ERCP) and subsequent LC and the third arm underwent laparoscopic cholecystectomy (LC) + laparoscopic CBD exploration (LCBDE) + primary closure of CBD. The duration of the entire trial is two years including prearrangement, follow-up and analyses. Discussion: Despite the fact plenty evidences provided by meta-analyses suggests that these approaches would appear comparable. It is hopeful to fully address which would be the better approach with this RCT design.
