Thomas' sign is the production of silver stools and can be indicative of cancer of the Ampulla of Vater. The ampulla of Vater is the site of tumors, often with a threatening prognosis and difficult surgical treatment. The silver-colored stool is a combination of the white stool of obstructive jaundice combined with black stool of melena or ...
Periampullary cancer is a cancer that forms near the ampulla of Vater, an enlargement of the ducts from the liver and pancreas where they join and enter the small intestine. [1] It consists of: ampullary tumour from ampulla of Vater; cancer of lower common bile duct; duodenal cancer adjacent to ampulla; carcinoma head of pancreas
Intra-ampullary papillary–tubular neoplasms (IAPN) are precancerous neoplasms of the ampulla of Vater. [1] On histological examination the neoplasms exhibit both papillary and tubular features. [2] IAPN were first described in 2010. [1] They are rare; comprising 0.5% of gastrointestinal tumours. [1]
Jaundice is commonly caused by conditions such as pancreatic cancer, which causes blockage of the bile duct passing through the cancerous portion of the pancreas; cholangiocarcinoma, cancer of the bile ducts; blockage by a stone in patients with gallstones; and from scarring after injury to the bile duct during gallbladder removal.
The major duodenal papilla (papilla of Vater) is a rounded projection in the duodenum into which the common bile duct and pancreatic duct drain. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion.

The common hepatic duct is the first part of the biliary tract. [2] It is formed by the union of the right hepatic duct (which drains bile from the right functional lobe of the liver) and the left hepatic duct (which drains bile from the left functional lobe of the liver).
Cancer cells are cells that divide continually, forming solid tumors or flooding the blood or lymph with abnormal cells. [1] Cell division is a normal process used by the body for growth and repair. A parent cell divides to form two daughter cells, and these daughter cells are used to build new tissue or to replace cells that have died because ...
