Cholangioscopy allows for direct visualization and sampling of biliary abnormalities that are concerning for malignancy. It is also instrumental in the management of difficult bile duct stones and pancreatic duct stones. Recently, cholangioscopy has also been utilized to access difficult-to-approach targets within the biliary tree and retrieve migrated stents. New enhancements, specifically better imaging, of the single-operator cholangioscope system have made this system easier to use. These innovations have demonstrated an improved detection of malignancy over combination endoscopic retrograde cholangiopancreatography (ERCP) techniques.
