Endoscopic retrieval of a proximally migrated biliary stent using extracorporeal shockwave lithotripsy, electrohydraulic lithotripsy, and cholangioscopy with minisnare.

Abstract

Video 1ERCP was notable for a proximally migrated biliary stent. Cholangiogram demonstrated multiple filling defects consistent with choledocholithiasis surrounding the proximally migrated biliary stent. Retrieval of the stent was successful using cholangioscopy-directed electrohydraulic lithotripsy, extracorporeal shockwave lithotripsy, mechanical lithotripsy, and minisnare over the course of 2 ERCPs. Complete duct clearance of stones was accomplished with balloon sweeps.
