Ampulla of Vater
Organ duct / From Wikipedia, the free encyclopedia
Not to be confused with the Duodenal cap also known as the duodenal ampulla, the first part of the duodenum.
The ampulla of Vater, hepatopancreatic ampulla or hepatopancreatic duct is the common duct that is usually formed by a union of the common bile duct and the pancreatic duct within the wall of the duodenum. This common duct usually features a dilation ("ampulla"). The common duct then opens medially into the descending part of the duodenum at the major duodenal papilla. The common duct usually measures 2-10mm in length.[1]
