BACKGROUND AND AIMS: Patients with Billroth II (B-II) gastrectomy present technical difficulties during endoscopic stone removal due to altered anatomy. Although endoscopic sphincterotomy alone or endoscopic balloon dilation alone has been used for removal of bile duct stones in patients with B-II gastrectomy, the results are not satisfactory. The aim of this study was to evaluate the efficacy and safety of endoscopic papillary large balloon dilation (EPLBD) for removal of bile duct stones in patients with B-II gastrectomy.

METHODS: Twenty-six patients (20 men and six women; median age 72 years) with bile duct stones and a history of B-II gastrectomy were enrolled. After cannulation, limited endoscopic sphincterotomy was performed. Then, balloon dilation (balloon size, 10-15 mm) was performed and stones were removed conventionally or via mechanical lithotripsy. Successful stone removal and complications were evaluated.

RESULTS: In all cases, stones were successfully removed. The median number of sessions for complete stone removal was one (range 1-3). Stone removal by mechanical lithotripsy was achieved in three patients (11.5%). There were no significant complications, such as bleeding, pancreatitis, or perforation.

CONCLUSIONS: Endoscopic papillary large balloon dilation is an effective and safe method for removal of bile duct stones. We suggest consideration of this technique for removal of bile duct stones in patients with B-II gastrectomy.
