Pancreas divisum

From Wikipedia, the free encyclopedia

ICD9 = | ICDO = | OMIM = | MedlinePlus = 000247 | eMedicineSubj = radio | eMedicineTopic = 520 | MeshID = |Pancreas divisum is a congenital defect in which the ventral and dorsal ducts of the pancreas fail to fuse together. Pancreas divisum is the most common congenital anomaly of the pancreas.

Presentation

Normally, the dorsal duct regresses as it fuses with the ventral duct, resulting in the duct of Wirsung draining from the major papilla. In some cases, the remaining duct of Santorini will drain from the minor papilla, but this duct can atrophy.

Prognosis

Most patients are asymptomatic and there is no functional significance to the defect. However, it can result in recurrent pancreatitis in a very small number of patients.An association with adenoma of the minor papilla has been reported.
