Abstract
AIM: To evaluate the safety and effectiveness of endoscopic papillary large balloon dilation (EPLBD) for bile duct stone extraction in patients with periampullary diverticula. METHODS: The records of 223 patients with large common bile duct stones (>= 10 mm) who underwent EPLBD (12-20 mm balloon diameter) with or without limited endoscopic sphincterotomy (ES) from July 2006 to April 2011 were retrospectively reviewed. Of these patients, 93 (41.7%) had periampullary diverticula (PAD), which was categorized into three types. The clinical variables of EPLBD with limited ES (EPLBD + ES) and EPLBD alone were analyzed according to the presence of PAD. RESULTS: Patients with PAD were significantly older than those without (75.2 +/- 8.8 years vs 69.7 +/- 10.9 years, P = 0.000). The rates of overall stone removal and complete stone removal in the first session were not significantly different between the PAD and non-PAD groups, however, there was significantly less need for mechanical lithotripsy in the PAD group (3.2% vs 11.5%, P = 0.026). Overall stone removal rates, complete stone removal rates in the first session and the use of mechanical lithotripsy were not significantly different between EPLBD + ES and EPLBD alone in patients with PAD (96.6% vs 97.1%; 72.9% vs 88.2%; and 5.1% vs 0%, respectively). No significant differences with respect to the rates of pancreatitis, perforation, and bleeding were observed between EPLBD + ES and EPLBD alone in the PAD group (3.4% vs 14.7%, P = 0.095; 0% vs 0%; and 3.4% vs 8.8%, P = 0.351, respectively). CONCLUSION: EPLBD with limited ES and EPLBD alone are safe and effective modalities for common bile duct stone removal in patients with PAD, regardless of PAD subtypes.
