Endoscopic papillary large-balloon dilation with sphincterotomy for difficult common bile duct stones ≤12 mm: a prospective study

Abstract Background: Stone recurrence is a significant complication following endoscopic bile duct clearance. Endoscopic papillary large-balloon dilation (EPLBD) with biliary sphincterotomy (EBS) has shown satisfactory results in preventing recurrence of “large” common bile duct stones (CBDS). However, data on outcomes after EPLBD+EBS for CBDS ≤12 mm remain scarce. The present study prospectively evaluated the mid- and long-term efficacy of EPLBD+EBS for CBDS recurrence among this group of patients. Methods: Consecutive patients with CBDS ranging from 8-12 mm, treated with EPLBD+EBS
