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.
