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

Abstract

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.
