title: Double Common Bile Duct with Ectopic Drainage into the Stomach Found in Asymptomatic.
abstract: The case of a patient with asymptomatic double common bile duct that was identified by chance is presented. A 41-year-old man underwent esophagogastroduodenoscopy(EGD) as part of a regular health checkup, during which he was found to have an elevated lesion in the lesser curvature of the upper gastric corpus with bile draining from its tip. Further examination led to a diagnosis of double common bile duct from the left intrahepatic bile duct to the opening into the stomach. Morphological abnormalities of the biliary tree are commonly encountered in everyday gastroenterological practice, but a double common bile duct with an ectopic opening into the stomach is comparatively rare. It is also associated with an increased risk of developing cancer of the stomach or bile duct, and as such is a biliary abnormality that must be treated with caution. This case is reported together with a discussion of the literature.
