A case of an accessory common bile duct inserting near or on the minor duodenal papilla
revealed by ERCP. The patient had no symptoms related to the anomaly.
A review of the literature revealed 23 cases from the last 500 years. The accessory
bile ducts opened into the gastrointestinal tract at different distances from the
major duodenal papilla. In certain animals a double common bile duct is normal. The
anomalies are assumed to be caused by random subdivisioning of the hepatic diverticulum
early in organogenesis.
