Long-term recurrence of bile duct stones after endoscopic papillary large balloon dilation with sphincterotomy: 4-year extended follow-up of a randomized trial
BackgroundEndoscopic papillary large balloon dilation with biliary sphincterotomy (EPLBD + EBS) is safe and effective in patients with large common bile duct (CBD) stones. However, data on long-term outcomes after EPLBD + EBS remain limited. We sought to prospectively evaluate the long-term recurrence of CBD stones after EPLBD + EBS and to identify the associated factors.
