Abstract: Objective:To explore the feasibility，safety and short term clinical efficacy of primary suture of common bile duct after laparoscopic choledocholithotomy in patients with common bile duct stones.Methods:We retrospectively analyzed the clinical data from 27 cases of the primary suture of common bile duct after laparoscopic choledocholithotomy and 24 cases of T tube drainage after laparoscopic choledocholithotomy.Clinical data were compared between the two groups.Results:Compared with T tube drainage after laparoscopic choledocholithotomy[（6.03±2.08）d]，the postoperative hospital stay of the primary suture of common bile duct after laparoscopic choledocholithotomy was more short[（9.50±3.48）d，P<0.05）.Bile leakage was found in both groups，including 2 cases in the indwelling t-tube group and 1 case in the first-stage suture group.There were 4 cases of residual stones after indwelling T tube group.No biliary stricture and recurrence of stones occurred during the recent follow up of the postoperative patients.Conclusion:Under strict indications，the primary suture of common bile duct after laparoscopic choledocholithotomy is safe and feasible in the treatment of patients with common bile duct stones，and has the advantage of quick recovery.
