What is the basis of the bismuth Corlette staging classification of cholangiocarcinoma?
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.
What is a Klatskin tumor?
Listen to pronunciation. (KLAT-skin TOO-mer) Cancer that develops in cells that line the bile ducts in the liver, where the right and left ducts meet. It is a type of cholangiocarcinoma.
What are the types of cholangiocarcinoma?
The three main types of cholangiocarcinoma are:
- Intrahepatic bile duct cancers – Develop in the small bile duct branches within the liver.
- Perihilar bile duct cancers (Klatskin tumors) – Form at the hilum, the point where the hepatic ducts join together to exit the liver.
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 recommended treatment for cholangiocarcinoma at the distal CBD?
Treatment of resectable distal bile duct cancer may include: Surgery to remove the cancer, which may include a Whipple procedure. Stent placement or percutaneous transhepatic biliary drainage as palliative therapy, to relieve jaundice and other symptoms and improve the quality of life.
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.
How is klatskin tumor diagnosed?
Abdominal imaging, visualization of the biliary tree and biopsies of the lesion are necessary to make the diagnosis. Endosonography (EUS) guided fine needle aspiration (FNA) of hilar lymph nodes is the most useful tool in the diagnosis and staging of Klatskin tumors.
What causes a klatskin tumor?
The cause of Klatskin tumors is unknown. Studies suggest that a combination of genetic, environmental, and lifestyle factors (multifactorial) likely influence whether a person will develop cholangiocarcinoma. Because Klatskin tumors are often discovered after they have spread, they can be challenging to treat.
Can you survive Klatskin tumor?
In the 109 patients with resected perihilar Klatskin tumors, the one-, three- and five-year survival was 68%, 30% and 11%, respectively. The median survival was 19 months.
Is Klatskin tumor intrahepatic extrahepatic?
Although hilar cholangiocarcinomas (Klatskin tumors) are extrahepatic cholangiocarcinomas, the second edition of the ICD-O (ICD-O-2) assigned them a histology code 8162/3, Klatskin, which was cross-referenced to intrahepatic cholangiocarcinoma.
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 the Roux-en-Y procedure?
Roux-en-Y gastric bypass (RYGB) is a type of weight-loss surgery. Weight-loss surgery is also called bariatric surgery. It’s often done as a laparoscopic surgery, with small incisions in the abdomen. This surgery reduces the size of your upper stomach to a small pouch about the size of an egg.
