What are the examination methods for bile duct cancer?

What are the examination methods for bile duct cancer? This is a question that patients with bile duct cancer are concerned about. Because many hospitals now do a lot of useless examinations, many patients are worried about wasting money on useless examinations, so they want to know the examination methods. So let us learn about it together today.

PTC: It is the main method for diagnosing bile duct cancer. It can show the location and range of bile duct cancer, and the diagnosis rate can reach 94% to 100%.

ERCP: The duodenal papilla can be directly observed, and the angiography can show the obstructed distal bile duct.

Angiography: Angiography can better determine whether bile duct cancer can be removed.

Cytological examination: On the basis of PTCD, the sinus tract is enlarged and a fiber choledochoscope is inserted to directly observe and clamp the mass for biopsy. When performing PTC or PTCD, bile can be extracted for cytological examination.

Ultrasound examination: Repeated and careful ultrasound examinations can show dilated bile ducts, obstructed sites, and even tumors. The ultrasound images of bile duct cancer can be mass-like, cord-like, protruding, and thrombus-like. Intrahepatic bile duct cancer often presents as a mass or cord-like, hilar cancer often presents as a cord-like, and lower bile duct cancer often presents as a protruding type. Thrombotic images of the hilar region may be hilar cancer, gallbladder cancer, or metastatic cancer. Since bile duct dilatation occurs before jaundice, ultrasound has the value of diagnosing early bile duct cancer.

Dietary considerations for bile duct cancer:

1. Try to reduce the intake of fat, especially animal fat, do not eat fatty meat or fried food, and replace animal oil with vegetable oil as much as possible.

2. A considerable part of the formation of cholecystitis and cholelithiasis is related to excessive cholesterol levels and metabolic disorders in the body. Therefore, you should limit the intake of foods with high cholesterol content, such as fish roe, egg yolks of various eggs, and liver, kidney, heart, and brain of various carnivorous animals.

3. It is best to cook food by steaming, boiling, stewing and braising. Avoid eating large amounts of stir-fried, deep-fried, roasted, grilled, smoked and pickled food.

4. Increase the intake of foods rich in high-quality protein and carbohydrates, such as fish, lean meat, soy products, fresh vegetables and fruits, to ensure the supply of calories, thereby promoting the formation of glycogen and protecting the liver.
