Background: Recently there has been growing interest in the duct system of pancreas as concerns its relationship with various disease processes as well as newer investigatory and treatment modalities related to them.This study has been aimed at evaluating the anatomy of the pancreatic duct system, thus identifying the variants to improve our knowledge of it and make things easier. The pancreas is formed by the fusion of the ventral and dorsal anlage, and a wide spectrum of anomalies or anatomical variations may appear related to this complicated process of fusion: e.g., agenesis, aplasia of a pancreatic anlage, hypoplasia, annular pancreas, pancreas divisum or nonfusion of the ventral and dorsal duct system, pancreaticobiliary maljunction, etc. Every endoscopist who engages in pancreatography or related diagnostic and therapeutic procedures should always be aware of all sorts of anatomical variations he or she might encounter.
