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 ...
Complications from surgical repair include Peptic ulcer disease, Gastroesophageal reflux disease, Cholecystitis, Esophagitis, Megaduodenum, Blind loop syndrome, and anastomotic leak. [10] Late complications may occur in about 12 percent of patients with duodenal atresia, and the mortality rate for these complications is 6 percent. [15]
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. [20] [citation needed]
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.
Then a flexible camera is inserted through the mouth, down the esophagus, into the stomach, through the pylorus into the duodenum where the ampulla of Vater (the union of the common bile duct and pancreatic duct) exists. The sphincter of Oddi is a muscular valve that controls the opening to the ampulla. The region can be directly visualized ...
Living among a small band of Neanderthals in what is now eastern Spain was a child, perhaps 6 years old, with Down syndrome, as shown in a remarkable fossil preserving traits in the inner ear ...
The VACTERL association (also VATER association, and less accurately VACTERL syndrome) refers to a recognized group of birth defects which tend to co-occur (see below). This pattern is a recognized association, as opposed to a syndrome , because there is no known pathogenetic cause to explain the grouped incidence.
On the endoscopic image of the ampulla, one can sometimes see a protuberant ampulla from an impacted gallstone in the common bile duct or the frank extrusion of pus from the common bile duct orifice. On the X-ray images (known as cholangiograms), gallstones are visible as non-opacified areas in the contour of the duct. For diagnostic purposes ...
