Abstract

There are a variety of anomalous lesions that can arise in the pancreaticobiliary system. Pancreaticobiliary maljunction (PBM), in which the junction of the bile duct and the pancreatic duct is external to the muscularis propria of the duodenum, is a factor contributing to choledochal cyst and biliary tract carcinoma. The pancreas consists embryologically of the ventral and dorsal anlagen, and is divided into two pancreata by the distribution of pancreatic polypeptide (PP)-islets. Anomalies based on two pancreata are pancreas divisum and annular pancreas.
