Featured: Pancreas Divisum Main Article
Pancreas divisum is a common congenital anomaly (an anomaly that is present at birth) of the pancreatic duct(s). The human embryo starts life with two ducts in the pancreas; the ventral duct and the dorsal duct. In more than 90% of the embryos, the dorsal and the ventral ducts will fuse to form one main pancreatic duct. In approximately 10% of embryos, the dorsal and the ventral ducts fail to fuse. Failure of the ventral and the dorsal pancreatic ducts to fuse is called pancreas divisum (because the pancreas is drained by two ducts). In pancreas divisum, the ventral duct drains into the major papilla, while the dorsal duct drains into a separate minor papilla. The majority of individuals born with pancreas divisum experience no symptoms throughout life, will remain undiagnosed and will not require treatment. A small number of patients with pancreas divisum will experience repeated episodes of pancreatitis.
