| Anatomical terminology | |
The major duodenal papilla (papilla of Vater) is a rounded projection in the duodenum into which the common bile duct and pancreatic duct drain. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion.

Variation
The major duodenal papilla is occasionally found in the junction between the descending and horizontal parts of the duodenum, or in the horizontal part of the duodenum; a case study of 1000 people demonstrated this in 12 and 8% respectively.
Function
Pancreatic enzymes and bile drain into the duodenum from both the
Clinical significance
The minor papilla drains the duct of Santorini, superior in position to the major papilla. In pancreatic divisum, in which the minor papilla drains the bulk of pancreatic secretions and major drains a minority of secretions (opposite of normal), a Santorinicele may develop leading to obstructed secretions/reflux resulting in pancreatitis.
History
The major duodenal papilla was first illustrated by
