AIM: To investigate the efficacy and outcomes of endoscopic papillary large balloon dilation (EPLBD) for bile duct stones in a multicenter prospective study. METHODS: Lithotomy by EPLBD was conducted in 124 patients with bile duct stones ≥ 13 mm in size or with three or more bile duct stones ≥ 10 mm. After endoscopic sphincterotomy, the papilla was dilated using balloons 12-20 mm in diameter fitting the bile duct diameter. RESULTS: The success rate of first-time lithotomy was 86.3% (107/124) and the final lithotomy success rate was 100% (124/124). Lithotripsy was needed in 10 of the 124 (13.6%) patients. Adverse events due to the treatment procedure occurred in 6 (4.8%) patients, all of which were mild. Performing large balloon dilation after endoscopic sphincterotomy in patients with large stones or multiple stones in the bile duct is considered to ensure the safety of treatment and to reduce the need for lithotripsy. CONCLUSION: It is suggested that treatment by EPLBD for large bile duct stones may be safe and useful.
