Abstract: Objective: To investigate the safety and feasibility of the postoperative primary suture of laparoscopic common bile duct exploration( LCBDE) . Methods: Eighty-two patients with choledocholithiasis treated with LCBDE were divided into primary suture group( 42 cases) and T tube drainage group ( 40 cases) . Results: The differences of operative time，blood loss and postoperative complications between two groups were not statistical significance ( P ＞ 0. 05 ) . The time of the first anus exhaust，postoperative ambulation and hospital stay in primary suture group were ( 24. 93 3. 29) hours，( 2. 39 1. 06) days and ( 6. 5 0. 51) days，respectively，which was significantly less than those in T-tube group( P ＜ 0. 01) . Conclusions: The postoperative selective primary suture of LCBDE is safe and feasible，which can significantly shorten the recovery time， promote early recovery and be worth being further popularized
