Objective To explore the effectivity and feasibility of uindirectional barbed suture for primary closure of common bile duct on Laparoscopic Exploration of Common Bile Duct Stones, Methods From January 2013 to August 2015,109 cases of primary closure of common bile duct after Laparoscopic Exploration of Common Bile Duct Stones were performed in this hospital.The characteristics of these cases were retrospectively comparatively analyzed.Results Conventional braided Sutures in 68 cases(group A),barbed Suture Devices in 41 cases (group B).There was no difference in postoperative hospital stay,intraoperative blood loss and complication rate between the two groups.Differences in bile duct incision suture time and operative time between the two groups were significantly different.Conclusion The application of uindirectional barbed suture for primary closure of common bile duct using barbed suture after Laparoscopic Exploration is a safe and effective way after treatment of choledocholithiasis.This method cuold reduce the difficulty of operation,and shorten the operation time and the learning curve.
