Peroral cholangioscopy for diagnosis and treatment of biliary diseases

Abstract

Peroral cholangioscopy is used for the diagnosis of biliary strictures and treatment of biliary stones. Recent advances in cholangioscope technology have improved the accuracy of diagnosing biliary neoplasms and its lateral extent. A new cholangioscopy system with a 4-way tip deflection system and a dedicated water irrigation channel has enabled easy lithotripsy with clear views, resulting in improved success rates and shortened procedure times. This newly developed system can be applied to a wide range of biliary interventions and trouble shootings.
