Abstract
Peroral cholangioscopy (POC) is an endoscopic procedure that allows direct intraductal visualization of the biliary tract. POC has emerged as a vital tool for indeterminate biliary stricture evaluation and treatment of difficult biliary stones. Over several generations of devices, POC has fulfilled additional clinical needs where other diagnostic or therapeutic modalities have been inadequate. With adverse event rates comparable to standard endoscopic retrograde cholangioscopy and unique technical attributes, the role of POC is likely to continue expand. In this frontiers article, we highlight the existing and growing clinical applications of POC as well as areas of ongoing research.
Core Tip: Cholangioscopy is an endoscopic technique that was first developed in the 1970s as a minimally-invasive modality for the evaluation of various biliopancreatic pathologies. Since the advent of the digital single-operator cholangioscopy (D-SOC) in 2015 as well as other, complementary advancements in the field, diagnostic and therapeutic applications have further expanded. Herein, we discuss the various current applications of cholangioscopy, with a focus on D-SOC, and areas of ongoing research to better understand potential future directions.
