Abnormal pancreas morphology Pancreas divisum 2017-05-13T13:56:45Z In pancreas divisum, the majority of the pancreatic gland drains into the minor papilla via the duct of Santorini, whereas the posterior head and uncinate process drain into the major papilla via the duct of Wirsung with the common bile duct. Although most patients are asymptomatic, in some patients, this anomaly is associated with recurrent acute pancreatitis because of inadequate drainage of pancreatic secretions via the minor papilla. A congenital anomaly of the pancreas that results from failed fusion of the dorsal and ventral ducts during embyological development. Three variants have been described: type 1 or classical divisum in which there is total failure of fusion; type 2 in which dorsal drainage is dominant in the absence of the duct of Wirsung; and type 3 or incomplete divisum where a small communicating branch is present.
