Ampulla Of Vater

Information about Ampulla Of Vater



The pancreatic duct.

The ampulla of Vater, seen on duodenoscopy at the time of ERCP
Latin	a. hepatopancreatica
	subject #250 1199
MeSH	Ampulla+of+Vater

The ampulla of Vater, also known as the hepatopancreatic ampulla, is formed by the union of the pancreatic duct and the common bile duct. The ampulla is specifically located at the major duodenal papilla.

Function

Various smooth muscle sphincters regulate the flow of bile and pancreatic juice through the ampulla: the sphincter of the pancreatic duct, the sphincter of the bile duct, and the hepatopancreatic sphincter (sphincter of Oddi).

The sphincter of Oddi controls the introduction of bile and pancreatic secretions into the duodenum, as well as preventing the entry of duodenal contents into the Ampulla.

Related disorders

Pancreatitis can result from a failure of pancreatic secretions to drain properly. One possible cause of impaired drainage of pancreatic juice is blockage of the hepatopancreatic ampulla. A common culprit to cause blockage is a gallstone in the common bile duct.

Eponym

The eponymical term "ampulla of Vater" is named after Abraham Vater (1684-1751), a German anatomist who first published a description of it in 1720.^[1]
