How can bile duct cancer be diagnosed

How can bile duct cancer be diagnosed? Biliary duct cancer is a malignant tumor disease of the digestive system. Since this disease is not common in life, it is difficult for people who have not tried it to find and treat it in time. So how can bile duct cancer be diagnosed? The following experts will give us a detailed introduction, I hope it will be helpful to you:

1. Ultrasound examination can show the dilated bile duct and the site of obstruction caused by cold obstruction, and occasionally a tumor can be detected.

2. Percutaneous transhepatic cholangiography (PTC) is an important method for diagnosing cholangiocarcinoma. It can show the condition of the intrahepatic bile duct and the site of obstruction, thereby clarifying the location and invasion range of the tumor. It can also be used to insert a cannula into the obstruction site to obtain living tumor tissue for pathological examination to obtain a clear diagnosis.

3. ERCP can show the obstructed distal bile duct and, when used in combination with PTC, can show the extent of bile duct obstruction.

4. CT and MRI examinations can show the extent of tumor invasion and whether there is metastasis to the abdominal lymph nodes.

5. Angiography: Selective arteriography can show the vascular condition of cholangiocarcinoma itself, and percutaneous transhepatic portal vein angiography (PTP) can understand whether the portal vein is affected.

6. Other examinations such as laparoscopy, serum immunology examination and general laboratory tests can be used for auxiliary diagnosis of cholangiocarcinoma.
