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
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 ...
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 pancreatic duct joins the common bile duct just prior to the ampulla of Vater, after which both ducts perforate the medial side of the second portion of the duodenum at the major duodenal papilla. There are many anatomical variants reported, but these are quite rare. [2]
Hemosuccus pancreaticus is a rare cause of hemorrhage in the gastrointestinal tract.It is caused by a bleeding source in the pancreas, pancreatic duct, or structures adjacent to the pancreas, such as the splenic artery, that bleed into the pancreatic duct, which is connected with the bowel at the duodenum, the first part of the small intestine.
The law does not say that these symptoms automatically mean pancreatic cancer. It just happens that pancreatic cancer is the most common cause that falls under Courvoisier's law. [ 4 ] Other cause includes malignancy of the CBD (i.e. cholangiocarcinoma ), head of pancreas and ampulla of Vater .
