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]
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
Other biliary tract cancers include gallbladder cancer and cancer of the ampulla of Vater. [7] Risk factors for cholangiocarcinoma include primary sclerosing cholangitis (an inflammatory disease of the bile ducts), ulcerative colitis, cirrhosis, hepatitis C, hepatitis B, infection with certain liver flukes, and some congenital liver malformations.
Most neuroblastomas are diagnosed in children under 5, the Cleveland Clinic says, adding that by the time symptoms appear, the cancer has spread to other parts of the body.
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 double duct sign is a radiological finding characterized by the simultaneous dilation of the common bile duct and the main pancreatic duct.This sign is significant because it often indicates an obstruction in the distal bile duct and pancreatic duct, frequently caused by serious underlying pathologies such as pancreatic carcinoma or periampullary tumors. [1]
A worm may block the ampulla of Vater, or go into the main pancreatic duct, resulting in acute pancreatitis with raised serum levels of amylase and lipase. Occasionally, a worm can travel through the biliary tree and even into the gallbladder , causing acute cholangitis or acute cholecystitis .
