Double-Needle Bidirectional Barbed Wire Continuous Layered Suture Technique for Laparoscopic Stage I Common Bile Duct Surgery

Background: Laparoscopic common bile duct exploration (LCBDE) proves a safe and effective treatment for choledochal stones. After LCBDE, preferred choledochal closure is favored for short- and long-term outcomes compared with t-tube drainage. However, there are no relevant studies on the technique of layered closure of the common bile duct with double-needle bidirectional barbed suture at home and abroad.Materials and Methods: A retrospective study of 37 patients who underwent laparoscopic choledochotomy from January 2021 to October 2023 in our hospital was performed. A continuous layered one-stage suture using two-needle bidirectional barb wire. The primary outcomes were stone clearance, operative time, blood loss, and complications. Secondary outcomes were complications, length of hospitalization, and time to drain removal.Results: During the study period, laparoscopic surgery was successful in all cases, and the initial stones were removed without complications.Conclusion: The treatment of choledocholithiasis with continuous layered one-stage suture with double-needle bidirectional barbed wire after LCBDE is a new convenient and effective treatment in selected patients.
