2022年9月16日 · The ampulla of Vater, or hepatopancreatic ampulla, is a small reservoir where your common bile duct and pancreatic duct meet. It collects bile and pancreatic juices. As part of your digestive system, the ampulla allows digestive juices to meet and break down food after it travels from your stomach to your small intestine.

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").

2014年6月20日 · Coronal multiplanar reformation CT image shows polyploid mass (arrow) at ampulla obstructing both pancreatic duct and common bile duct. This mass was found to be ampullary carcinoma.

2024年7月5日 · It joins the pancreatic duct at the ampulla of Vater, which drains into the second part of the duodenum through the major duodenal papilla. Of note, for decades, what had been labeled CBD in much of the radiology literature is now known to have usually been the common hepatic duct (CHD).

The distal common bile duct (CBD) and ampulla are extremely difficult sites to evaluate on CT. This article seeks to provide the reader with a framework and algo-

The bile duct [1] [4] (formerly known as the common bile duct [4]) is a part of the biliary tract. [4] It is formed by the union of the common hepatic duct and cystic duct. It ends by uniting with the pancreatic duct to form the hepatopancreatic ampulla. It possesses its sphincter to enable the regulation of bile flow.

2020年11月20日 · The hepatopancreatic ampulla, also called the hepatopancreatic duct or ampulla of Vater, is a spherical structure located at the site of the confluence of the common bile duct and pancreatic duct, marking the entry point of bile into the second portion of the duodenum.

2021年12月13日 · The ampulla of Vater is a conical structure at the confluence of the common bile duct (CBD) and the main pancreatic duct that protrudes through a natural dehiscence of the duodenal wall at the major duodenal papilla into the medial aspect of the descending duodenum.

2024年4月22日 · The hepatopancreatic ampulla, also known as the ampulla of Vater, is a small spherical reservoir located at confluence of the common bile duct and pancreatic duct. It is found within the wall of the descending duodenum and terminates in its lumen a small elevation called the duodenal papilla.

2014年5月1日 · The ampulla of Vater is an important anatomic landmark where the common bile duct and main pancreatic duct converge in the major duodenal papilla. Imaging evaluation of the ampulla and periampullary region poses a unique diagnostic challenge to radiologists because of the region’s complex and variable anatomy and the variety of lesions that ...
