Purpose: The aim of this study is to assess the long-term results of laparoscopic common bile duct exploration (LCBDE) and validate its effectiveness as a primary treatment modality for CBD stone. Methods: a retrospective review of the medical records of 157 patients who underwent LCBDE from 1997 to 2011 was conducted. All LCBDE were performed by choledochotomy. Clinical demographics, operative outcome, recurrence rate of CBD stones, and long-term bile duct complications were analyzed. The mean follow-up period was 51.9 months. Results: LCBDE was completed in 152 patients (96.8%) and 5 patients (3.2%) had open conversion. The male/female ratio was 78/79 and mean age was 67.3 years. Stone clearance was successful in 149 of 152 patients (98.0%). Nonlethal complications were noted in 11 patients (7.2%), including bile leakage in 6 patients (3.9%). Recurrent CBD stones developed in 9 of 152 patients (5.9%). Preoperative endoscopic sphincterotomy (P = 0.492) and choledochotomy repair type (T-tube drainage vs. primary closure, P = 0.740) were not significantly related to stone recurrence. There were no signs of any type of biliary injury or stricture observed in any of the patients during the follow-up period. Conclusion: LCBDE can be performed without increased risk of long-term complications such as bile duct stricture and recurrent CBD stones. LCBDE is a safe and effective treatment option for choledocholithiasis in terms of long-term outcome as well as short-term outcome.
