<![CDATA[Cholangiocarcinoma is a disease caused by the differentiation of cells in the bile epithelium or liver parenchyma into malignant cells called cholangiocytes. This literature review presents the current risk factors, diagnostic tools, and treatment choices of cholangiocarcinoma. Publication about the current risk factors, diagnostic tools, and treatment choices of cholangiocarcinoma were collected from the Pubmed database until August 25, 2022. The keywords of the research were “cholangiocarcinoma”, “risk factor”, “diagnostic”, and “treatment”. Cholangiocarcinoma has many risk factors, from choledochal cysts, and primary sclerosing cholangitis, to asbestos exposure. The diagnosis of cholangiocarcinoma is difficult and requires the combined interpretation of different diagnostic modalities. Examinations that can be done for the diagnosis and staging of cholangiocarcinoma are MRI and CT. However, if the diagnosis remains uncertain, endoscopic examination and tissue sampling may be performed. After the diagnosis, there are several treatments, namely surgical therapy (surgical excision of bile duct tumors), endoscopic therapy (endoscopic biliary dilatation), radiological therapy (percutaneous transhepatic palliative biliary dilatation), chemotherapy and radiotherapy, and photodynamic therapy.
