What are the causes of hilar cholangiocarcinoma?

Hilar cholangiocarcinoma refers to hilar cholangiocarcinoma. The etiology of hilar cholangiocarcinoma is not clear, and it may be related to chronic hepatitis virus infection, bile duct stones, bile duct parasites and other reasons.

1. Chronic hepatitis virus

infection such as hepatitis B virus and hepatitis C virus infection can cause continuous inflammation of the liver, which is easy to cause damage and regeneration of liver cells, which may lead to hilar cholangiocarcinoma.

2. Bile duct stones When the bile

duct stones are large, it may cause bile duct obstruction, which is also easy to induce inflammation, which may lead to hilar cholangiocarcinoma.

3. Bile duct parasites

infection may lead to local tissue damage. After damage, the tissue will be repaired for a long time. Damage and repair easily lead to abnormal proliferation of cells, and eventually cause disease.
