Electrohydraulic Lithotripsy for Hepatolithiasis With Novel VedVision Cholangioscope and New Biodegradable Stent (UNITY-B) for Intrahepatic Biliary Stricture: A Case Report With Video.

ABSTRACT: Cholangioscopy has improved the management of complex biliary diseases; however, digital single-operator cholangioscopy (DSOC) still faces key limitations, especially in treating intrahepatic disease like hepatolithiasis and strictures, which often require surgery with significant mortality risk. This video case report illustrates the successful endoscopic treatment of an elderly woman with multiple left intrahepatic duct stones and a benign stricture. A next-generation 11-Fr high-definition cholangioscope (VedVision) was employed, offering enhanced imaging, improved maneuverability, and a dual-channel system enabling simultaneous guidewire and lithotripsy probe use. Electrohydraulic lithotripsy achieved complete stone clearance. A balloon-expandable biodegradable stent (UNITY-B), composed
