Objective To explore the feasibility and surgical techniques of primary suture by rigid choledochoscope combined with laparoscopic common bile duct exploration.Methods Clinical materials of 53 patients with primary suture by rigid choledochoscope combined with laparoscopic common bile duct exploration were analyzed retrospectively.Results 53 patients completed opera-tions successfully.The operating time was 90 to 168 minutes,with average duration of 112 min-utes.Postoperative hospital stay was 6 to 9 days,with an average length of 6.6 days.No postoper-ative complications such as bleeding,abdominal infection,bile leakage,bile duct stricture and resid-ual biliary stones were observed.Conclusion Under the premise of strictly selecting cases with common bile duct stones,rigid choledochoscope combined with laparoscopic common bile duct explo-ration for primary suture is a feasible method,it has the advantages of less trauma,fast recovery and short hospital stay,so it is worthy of popularization.
