Abstract

PURPOSE: Application of a laparoscopic technique to common bile duct explorations has been limited due to technical difficulty. With increased experience and technique, laparoscopic surgery has become a possible option for the treatment of common bile duct stones. The purpose of this study was to assess the usefulness of laparoscopic surgery in the treatment of common bile duct stones. METHODS: Between March 1997 and August 1999, 35 patients with choledocholithiasis were treated with laparoscopic common bile duct exploration (4 had a previous biliary operative history). Intraoperative choledochoscopy was used to remove common bile duct stones. The stones were retrieved by using a saline flush, a basket, or a Fogarty catheter. The impacted stones were destroyed using electrohydraulic lithotripsy. RESULTS: Successful laparoscopic stone clearance was achieved in 33 cases (94.3%), and conversion to open surgery occurred in one case (2.9%). The morbidity was 5.7% without mortality. Two cases of retained stone were treated with postoperative choledochoscopic removal via fistula tract and postoperative endoscopic extraction. CONCLUSION: Laparoscopic common bile duct exploration is feasible and safe in most patients. With increased of experience, laparoscopic common bile duct exploration could be used widely.
