Successful intervention using multiloop traction for cases with difficult biliary cannulation due to periampullary diverticula

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.

Texture and color enhancement imaging aided in the identification of a deviated bile duct orifice in a patient with a large periampullary diverticulum

Deviation of the bile duct orifice due to a large periampullary diverticulum presents difficulty in identifying the bile duct orifice, resulting in failure to achieve selective biliary cannulation. Tanisaka and colleagues demonstrate the usefulness of texture and color enhancement imaging for the identification of a deviated bile duct orifice.
