Pancreaticobiliary maljunction

Pancreaticobiliary maljunction is a congenital malformation, in which the pancreatic and bile ducts join anatomically outside the duodenal wall, forming a markedly long common channel.[1] This anomaly prevents normal control by the sphincter of Oddi located in the duodenal wall, allowing regurgitation of pancreatic juices into the biliary tract and possibly leading to a higher probability of pancreaticobiliary cancers.
