The duration of bile duct removal survival depends largely on the specific nature of the lesion. For benign lesions undergoing choledochotomy, such as congenital bile duct dilatation, patients can achieve long-term survival after surgery, which is even consistent with normal survival. Of course, there are some patients who may have recurrent biliary duct infections, bile duct stones, or even bile duct cancer after surgery, which can seriously affect the survival of patients. For bile duct resection for gallbladder, bile duct, pancreatic head or periampullary cancer, even if radical treatment can be achieved, recurrence and metastasis are likely to occur after surgery, and the current 5-year overall survival rate does not exceed 30%. Patients with palliative surgery may even die within a year, while a few patients can survive for more than 10 years, mainly in the early stage of bile duct cancer and periampullary cancer. The prognosis of pancreatic cancer is poor, with a 5-year survival rate of almost less than 10%, so it depends on the type of pathology and the stage of the disease.
