Cholangioscopy 

Per-oral Cholangioscopy

Peroral cholangioscopy is a type of cholangioscopy, that is a minimally invasive advanced endoscopic procedure that allows for real-time definition visualization of the biliary tree.



A small catheter that has a high-resolution fiber optic probe is inserted through the endoscopic retrograde cholangio-pancreatography scope.




There is an additional port through which accessories can be passed for interventional procedures. The entire architecture through which bile flows can be checked for a variety of problems.
