Citation, DOI & article data
The ansa pancreatica is a rare type of anatomical variation of the pancreatic duct. It is a communication between the main pancreatic duct (of Wirsung) and the accessory pancreatic duct (of Santorini). Recently, the ansa pancreatica has been considered as a predisposing factor in patients with idiopathic acute pancreatitis 3.
The ansa pancreatica arises as a branch duct from the main pancreatic duct. It descends down initially, it then ascends upward forming a loop finally terminating at the minor papilla.
History and etymology
It is derived from the Latin "ansa", which means "handle" as its configuration resembles a handle.
