Patient Data

Age: 70
Gender: Female

The main pancreatic duct (of Wirsung) enters the duodenum in the conventional location at the major ampulla with the CBD.  The duct  (of Santorini) draining the uncinate process enters the duodenum proximally at the minor ampulla.  An abnormal duct joins the main pancreatic duct in the region of the head to the minor ampulla - this is known as ansa pancreatica (i.e. the handle of the pancreas - this accessory duct looking like a handle)

Case Discussion

Ansa pancreatica is a rare variant and is said to predispose to idiopathic acute pancreatitis.
