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").
It is surrounded by the sphincter of Oddi, a circular muscle, and receives a mixture of pancreatic enzymes and bile from the Ampulla of Vater, which drains both the pancreatic duct and biliary system. [2] The junction between the foregut and midgut occurs directly below the major duodenal papilla.
The pancreatic duct joins the common bile duct just prior to the ampulla of Vater, after which both ducts perforate the medial side of the second portion of the duodenum at the major duodenal papilla. There are many anatomical variants reported, but these are quite rare. [2]
The path is as follows: bile canaliculi → canals of Hering → interlobular bile ducts → intrahepatic bile ducts → left and right hepatic ducts merge to form → common hepatic duct exits liver and joins → cystic duct (from gall bladder) forming → common bile duct → joins with pancreatic duct → forming ampulla of Vater → enters ...
Vater is primarily known for his work in anatomy, but he also published works in the fields of chemistry, botany, pharmacology and gynaecology. He was the first to describe the hepatopancreatic ampulla, which is the juncture of the pancreatic duct and the common bile duct, and is now referred to as the ampulla of Vater.
