OBJECTIVE: Endoscopic sphincterotomy (ES) is an established method to treat common bile duct (CBD) stones. Inevitable sequence after ES is a substantial risk of recurrent choledocholithiasis and occasional difficulty in removal of large or multiple CBD stones after ES even when mechanical lithotripsy (ML) is employed. In turn, a new endoscopic technique, large balloon dilation (LBD) after ES, has been introduced. The objective was to analyze the efficacy and safety of LBD in patients with recurrent bile duct stones who have previously undergone ES. PATIENTS AND METHODS: From December 2007 to November 2009, 24 patients with recurrent choledocholithiasis and a history of ES were treated with LBD without additional ES. The size of the balloon for LBD was 15-20 mm and the duration of balloon dilation was 30 s. RESULTS: Successful stone removal and complications such as perforation, pancreatitis, and bleeding were evaluated as procedure-related outcomes. Postoperative CBD stone recurrence was evaluated as the short term outcome. Complete duct clearance rate without using ML was 96% (23/24 patients) and all stone removal was achieved in one session. Failure to remove stones occurred in one (4.2%) patient. There were no procedure-related complications although one case of aspiration pneumonia occurred after the endoscopy. Recurrent choledocholithiasis after LBD was observed in 12.5% (3/24) of the cases overall. CONCLUSIONS: LBD is an effective and safe method in patients with recurrent choledocholithiasis not only to treat large stones but also to prevent further recurrence.
