Ampulla of Vater
(Redirected from Hepatopancreatic ampulla)
Ampulla of Vater
The Ampulla of Vater, also known as the hepatopancreatic ampulla or the confluence of the bile duct and the pancreatic duct, is a crucial anatomical structure in the digestive system. It is named after Abraham Vater, a German anatomist who first described it in the 18th century.
Anatomy[edit | edit source]
The Ampulla of Vater is located in the second part of the duodenum, the first section of the small intestine. It is the point where the common bile duct and the main pancreatic duct converge. This junction is surrounded by the sphincter of Oddi, a muscular valve that controls the flow of bile and pancreatic juice into the duodenum.
Function[edit | edit source]
The primary function of the Ampulla of Vater is to facilitate the transport of bile and pancreatic juice, which are essential for digestion. The bile, produced by the liver and stored in the gallbladder, helps in the digestion and absorption of fats. The pancreatic juice, produced by the pancreas, contains enzymes that aid in the digestion of proteins, carbohydrates, and fats.
Clinical Significance[edit | edit source]
Diseases and conditions affecting the Ampulla of Vater can have significant health implications. These include ampullary cancer, choledocholithiasis (gallstones in the bile duct), and pancreatitis. Diagnosis of these conditions often involves imaging studies such as endoscopic retrograde cholangiopancreatography (ERCP) and magnetic resonance cholangiopancreatography (MRCP). Treatment may involve endoscopic procedures, surgery, or medication, depending on the specific condition and its severity.
