Cholangiocarcinoma fitted with drainage tube can survive for a long time and will not affect life. This is because if cholangiocarcinoma is fitted with drainage tube, it means that the patient has been treated with cholangiocarcinoma tumor resection, which indicates that the patient is in the early stage of cholangiocarcinoma. Early stage cholangiocarcinoma patients can survive for a long period of time if they actively undergo surgery to remove the cholangiocarcinoma tumor, and it will not affect the life of patients. After the surgery for bile duct tumor, the patient has a drain installed, the purpose of which is to drain the bile to prevent bile stagnation, inflammation of bile duct and bile duct stones. Every day, the patient should observe whether the drain is smooth, the color of the drainage liquid and the amount of drainage flow, and consider removing the drain after 4 weeks or so, and an imaging is needed before removing the drain to see whether the drain is smooth or not. Patients after cholangiocarcinoma surgery should go to the hospital in time if they have any discomfort, so as to avoid delaying the treatment.
