Congenital left intrahepatic bile duct draining into gastric wall mimicking biliary reflux gastritis

摘要

Abnormalities and variations of the biliary ducts are not rare.Most aberrant bile ducts eventually drain into the descending part of duodenum through the papilla of vater.However,drainage of the left hepatic bile duct into the stomach is extremely rare.A 29-year old man was admitted to the hospital with the diagnosis of biliary reflux gastritis.Comprehensive imaging modalities were performed including electronic endoscopy,endoscopic ultrasonography,endoscopic retrograde cholangiopancreatography and magnetic resonance cholangio-pancreatography.Finally,congenital ectopic left intrahepatic bile duct draining into the stomach was found,which caused biliary reflux gastritis.The patient did not receive any surgery.Good recovery was achieved by medical treatment.
