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 basis of the Bismuth Corlette staging classification of cholangiocarcinoma?
The Bismuth-Corlette classification is a classification system for perihilar cholangiocarcinomas, which is based on the extent of ductal infiltration.
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). [1. Cholangiocarcinoma.
What is hilar cholangiocarcinoma?
Hilar cholangiocarcinoma is a type of bile duct cancer that occurs in the bile ducts that lead out of the liver (hepatic ducts) and join with the gallbladder. Hilar cholangiocarcinomas are also known as Klatskin tumors.
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 the survival rate of cholangiocarcinoma?
If the cancer is diagnosed in an early stage, the 5-year survival rate is 15%. If the cancer has spread to the regional lymph nodes, the 5-year survival rate is 16%. If the cancer has spread to a distant part of the body, the 5-year survival rate is 2%. The 5-year survival rate for intrahepatic bile duct cancer is 9%.
What is a Hepaticojejunostomy procedure?
A hepaticojejunostomy is the surgical creation of a communication between the hepatic duct and the jejunum; a choledochojejunostomy is the surgical creation of a communication between the common bile duct (CBD) and the jejunum.
What is a Choledochojejunostomy?
Choledochojejunostomy is a procedure for creating an anastomosis of the common bile duct (CBD) to the jejunum, performed to relieve symptoms of biliary obstruction and restore continuity to the biliary tract.
Which parasite causes cholangiocarcinoma?
In areas where liver flukes are endemic and a person may have multiple long-standing untreated liver fluke infections, the inflammation of the gallbladder and ducts caused by the parasite has been associated with liver and bile duct cancers, including cholangiocarcinoma.
What is the bismuth-Corlette classification for Perihilar cholangiocarcinomas?
Bismuth-Corlette classification is a classification system for perihilar cholangiocarcinomas: Type I: limited to the common hepatic duct, below the level of the confluence of the right and left hepatic ducts
What is the bismuth-Corlette classification for hepatic duct cancer?
The Bismuth-Corlette classification is a classification system for perihilar cholangiocarcinomas, which is based on the extent of ductal infiltration. type II and extends to involve the origin of the right hepatic duct (confluence of the right posterior and anterior sectoral ducts)
What are the subtypes of perihilar cholangiocarcinoma?
It is classified into intrahepatic and extrahepatic, with further subtypes as mass forming, periductal infiltrating and intraluminal. Bismuth-Corlette classification is a classification system for perihilar cholangiocarcinomas: Type I: limited to the common hepatic duct, below the level of the confluence of the right and left hepatic ducts
What are the signs and symptoms of bismuth Corlette Type IIIA?
Intrahepatic bile duct dilatation with an ill defined, mildly T2 hyperintense mass at the hilum. Infiltrative hilar mass shows progressive delayed enhancement (arrow). The hilar mass extends to involve the branches of right hepatic duct (arrow), consistent with Bismuth Corlette Type IIIa.
