AdministratorWhat is the function of the ampulla of Vater?
The cystic duct leaves the gallbladder and joins with the common hepatic duct to form the common bile duct. This duct subsequently joins with the pancreatic duct; this junction is known as the ampulla of Vater. The pancreatic duct delivers substances such as bicarbonate and digestive enzymes to the duodenum.
What would happen if the hepatopancreatic ampulla was blocked by a gallstone?
If a gallstone was stuck in the hepatopancreatic ampulla, bile could back up and flow backwards into the main pancreatic duct. If a stone was lodged in the cystic duct, common hepatic duct, or common bile duct, bile would never even reach the pancreas.
What drains into the ampulla of Vater?
The ampulla, or ampulla of vater, is where the pancreatic duct and bile duct join together to drain into the duodenum, which is the first part of the small intestine.
Is the ampulla of Vater part of the duodenum?
The ampulla of Vater is located in the posteromedial wall of the second portion of the duodenum. The common bile duct (CBD) normally goes through an oblique, 1-2 cm long intramural region beside the medial wall of the second portion of the duodenum and opens into the duodenum.
Where does the ampulla of Vater open?

What is the inflammation of the gallbladder?
Acute cholecystitis is inflammation of the gallbladder. It usually happens when a gallstone blocks the cystic duct. Gallstones are small stones, usually made of cholesterol, that form in the gallbladder.
What happens to the gallbladder after the ampulla of Vater is removed?
After the ampulla of Vater is removed, the gallbladder does not function well and forms gallstones. The second and third portions of the duodenum share a blood supply with the head of the pancreas and are usually devascularized when the head is removed.
What is the ampulla of Vater?
The ampulla of Vater, also known as the hepatopancreatic ampulla or the hepatopancreatic duct, is formed by the union of the pancreatic duct and the common bile duct.
What is the incidence of lesions of the ampulla of Vater?
Lesions of the ampulla of Vater are rare histological entities with an incidence of between 0.1 and 0.2% of gastrointestinal tumors. Until recently the main response to this kind of lesion was duodenopancreatectomy, regardless of the cellular atypia and local edema.
What is the protrusion of the ampulla of Vater into the duodenum?
This is the protrusion of the ampulla of Vater into the duodenum. The ampulla of Vater, also known as the hepatopancreatic ampulla or the hepatopancreatic duct, is formed by the union of the pancreatic duct and the common bile duct. The ampulla is specifically located at the major duodenal papilla .
