Large balloon dilation for the treatment of recurrent bile duct stones prevents short-term recurrence in patients with previous endoscopic sphincterotomy

Background/purpose Our previous study revealed the efficacy and safety of the large balloon dilation (LBD) technique. However, there is insufficient objective data about the recurrence rate. The aim of this study was to compare the recurrence rate of common bile duct (CBD) stones between patients treated with and without LBD.
