What tests should patients with bile duct cancer undergo

The existence of diseases is a major threat to human life in today's world. Although society is constantly developing, technology is constantly advancing, medical skills are constantly improving, and research on diseases is becoming more and more in-depth, there are still many problems that cannot be overcome. Among them, bile duct cancer is one of them. Let us learn about what examinations bile duct cancer patients should do.

Patients with bile duct cancer should undergo the following tests:

1. Laboratory examination: Bilirubin. Laboratory examination of cholangiocarcinoma shows obstructive jaundice. Elevated serum total bilirubin and direct bilirubin show cholestatic jaundice. Liver function. In patients with long-term biliary obstruction, there may be secondary liver damage. Mild elevation of ALT and AST is a manifestation of secondary liver damage. Due to malnutrition and liver damage, serum total protein and albumin will decrease. Laboratory examinations

2. Imaging examination: The main purpose of imaging examination is to diagnose the location of obstruction, determine the possible nature of the lesion, estimate the scope of the lesion and its relationship with surrounding tissues and organs. B-ultrasound examination is available. Among many imaging examinations, B-ultrasound is the preferred diagnostic method. CT examination is still a conventional examination method. It can show the dilatation of intrahepatic and extrahepatic bile ducts, obvious dilatation of the proximal bile duct of the obstruction, enlarged gallbladder, sudden interruption of the dilated bile duct, irregular shape of the broken end, and mass shadows.

3. Histological diagnosis: The final diagnosis of the patient must be based on histological diagnosis. Cholangiocarcinoma can obtain histological specimens through percutaneous puncture, but in many cases, specimens for histological diagnosis are obtained by surgery.

I hope the above inspection methods will be helpful to everyone.
