What are the diagnostic items for bile duct cancer? Biliary duct cancer is a malignant tumor disease located under the liver. The harm and severity of this disease are beyond our imagination. So if you find yourself with symptoms similar to bile duct cancer, don't hesitate to go to the hospital for diagnosis and treatment in time. So what are the diagnostic items for bile duct cancer?

How is bile duct cancer diagnosed?

1. Laboratory examination: The main manifestations are abnormal liver function of obstructive jaundice, such as increased bilirubin and alkaline phosphatase.

2. Ultrasound and CT examinations: Both can observe uneven thickening of the gallbladder wall, and masses with fixed position and shape but varying strengths in the cavity. Tumor invasion of the liver and lymph node metastasis can also be found. According to clinical reports, the diagnostic accuracy of B-ultrasound examinations is 36% to 84%, and the diagnostic accuracy of CT examinations can reach 70%. The combined use of the two can improve the diagnostic rate.

3. PTC examination: It is one of the effective methods for diagnosing bile duct cancer. The PTC examination can observe the location and infiltration range of the tumor in the bile duct, and the clinical diagnosis rate can reach more than 94%.

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

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

6. Cytological examination: On the basis of PTCD, the sinus tract is enlarged and a fiber choledochoscope is inserted, so that the mass can be directly observed and clamped for pathological biopsy. When performing PTC or PTCD, bile can be extracted for cytological examination.
