Abstract
Purpose of Review
In 10–15% of the cases, conventional methods for removing bile duct stones by ERCP/balloon-basket extraction fail. The purpose of this review is to describe endoscopic techniques in managing these “difficult bile duct stones.”
Recent Findings
Endoscopic papillary large balloon dilation with balloon extraction ± mechanical lithotripsy is the initial approach used to retrieve large bile duct stones. With advent of digital cholangioscopy, electrohydraulic and laser lithotripsy are gaining popularity. Enteroscopy-assisted or laparoscopic-assisted approaches can be used for those with gastric bypass anatomy.
Summary
Difficulties in removing bile duct stones can be related to stone-related factors such as the size and location of the stone or to altered anatomy such as stricture in the bile duct or Roux-en-Y anatomy. Several endoscopy approaches and techniques have described in the recent past that have greatly enhanced our ability to remove these “difficult” bile duct stones.
