Future of Cholangioscopy.

This article highlights the current status of cholangioscopy. In addition, the authors present their view on the future directions of cholangioscopy, including novel clinical applications, the need for technologic developments, and the expansion on the use of cholangioscopy in clinical practice. The authors envision that cholangioscopy will eventually become a conventional tool in the shelf of any biliary endoscopist. Future technologic improvements including optics, maneuverability, and full device accessories, plus the introduction of real-time artificial intelligence algorithms, will optimize the outcomes of cholangioscopy, but baseline proficiency in therapeutic endoscopic retrograde cholangiopancreatography will remain necessary for its successful utilization.
