What is Bismuth classification?
The Bismuth classification is a simple classification based on the location of the injury in the biliary tract. This classification is very helpful in prognosis after repair.
What is the Bismuth Corlette classification?
The Bismuth-Corlette classification is a classification system for perihilar cholangiocarcinomas, which is based on the extent of ductal infiltration.
What is Bismuth IV cholangiocarcinoma?
A type IV lesion is a combination of Bismuth type IIIa and IIIb lesions, in which the tumor invades the second-order bile duct tributaries of both hepatic ducts [6].
How do you classify cholangiocarcinoma?
Cholangiocarcinomas are classified based on anatomical location (Figure 1) as intrahepatic (iCCA) and extrahepatic (eCCA). Extrahepatic CCA has then been further divided into perihilar (pCCA), also known as Klatskin tumours, and distal (dCCA).
What drug class is bismuth subsalicylate?
Bismuth subsalicylate is in a class of medications called antidiarrheal agents.
Is bismuth a semiconductor?
It has a high electrical resistivity. When deposited in sufficiently thin layers on a substrate, bismuth is a semiconductor, despite being a post-transition metal. Elemental bismuth is denser in the liquid phase than the solid, a characteristic it shares with germanium, silicon, gallium, and water.
Is bismuth a metal nonmetal or metalloid?
metal
Bismuth is a high-density, silvery, pink-tinged metal. Bismuth metal is brittle and so it is usually mixed with other metals to make it useful. Its alloys with tin or cadmium have low melting points and are used in fire detectors and extinguishers, electric fuses and solders.
What is Roux en Y Hepaticojejunostomy?
What is hepaticojejunostomy? A hepaticojejunostomy, or Roux-en-Y procedure, bypasses the bile duct to allow digestive juices to drain from the liver directly into the small intestine. The hepatic duct is the tubular channel that carries bile from the liver to the small intestine to aid digestion.
What is the use of bismuth?
People commonly use bismuth for travelers’ diarrhea, a digestive tract infection that can lead to ulcers (Helicobacter pylori or H. pylori), and stomach ulcers. It is also used for constipation, bleeding, and many other conditions, but there is no good scientific evidence to support these other uses.
Is bismuth a metal or nonmetal?
How is CCA diagnosed?
Computed tomography (CT) and magnetic resonance imaging (MRI) greatly assist in the diagnosis of CCA. iCCA takes up contrast agent progressively during the arterial and venous phases of studies— especially if the lesion is larger than 20 mm.
What is intrahepatic cholangiocarcinoma?
Intrahepatic cholangiocarcinoma occurs in the parts of the bile ducts within the liver and is sometimes classified as a type of liver cancer. Hilar cholangiocarcinoma occurs in the bile ducts just outside of the liver. This type is also called perihilar cholangiocarcinoma.
