Successful cholangioscopy‐guided cannulation using a novel slim cholangioscope

Selective biliary cannulation is a difficult step in endoscopic retrograde cholangiopancreatography. In this case video, Tanisaka and colleagues report a successful cholangioscopy‐guided cannulation achieved using a novel slim cholangioscope with a 2.3‐mm scope tip. Cholangioscopy‐guided cannulation using this cholangioscope could be a good option in cases of difficult biliary cannulation.
