Clinical impact of digital cholangioscopy in management of indeterminate biliary strictures and complex biliary stones: a single-center study.

Single-operator digital cholangioscope had a high success rate and a low rate of complications for management of indeterminate strictures and difficult biliary stones. Visual cholangioscopic features of biliary strictures had excellent diagnostic accuracy, and targeted biopsies outperformed brush cytology. Early implementation of cholangioscopy for select indications leads to successful patient outcomes and reduces diagnostic delays, cost, and risks of repeat endoscopic retrograde cholangiopancreatographies.
