Gastric duplication communicating with the left hepatic duct: a rare case of recurrent hemobilia in a child.

Gastric duplication is a rare anomaly, usually manifested as an abdominal mass or gastric outlet obstruction mimicking congenital hypertrophic pyloric stenosis during the first year of life. Occasionally, it communicates with the pancreatic duct and causes pancreatitis. However, communication with the intrahepatic bile duct has not been described. The authors report a rare case of gastric duplication that communicated with the left hepatic duct and caused recurrent hemobilia in a 2-year-old girl. Left hepatectomy and excision of the duplication were curative.
