The survival time of cholangiocarcinoma is mainly assessed according to the stage of cholangiocarcinoma. Early-stage cholangiocarcinoma can still have a good survival period if radical surgery is performed, and the survival can exceed 5, 10 or even longer years. The prognosis of intermediate and advanced cholangiocarcinoma decreases significantly, and even if surgical resection is performed, recurrence is likely to occur within 1-3 years after surgery. Many patients with advanced stages are beyond surgical treatment and insensitive to chemotherapy and radiotherapy, and are likely to die within 3-6 months. Currently, the overall 5-year survival rate of cholangiocarcinoma is about 30%. It is also a very malignant tumor of the digestive system, which is prone to metastasis along the bile duct wall and lymph nodes, which is one of the reasons why cholangiocarcinoma is prone to recurrence. In addition, surgery is also very important for the prognosis of common bile duct cancer, which should ensure negative choledochotomy margin and skeletonization of hepatoduodenal ligament, which can maximize the postoperative survival time of patients.
