The maximum survival time of a bile duct blockage needs to be determined by the specific cause of the blockage, which mainly depends on its primary condition.
If the blockage is caused by bile duct stones, as long as the stones are actively removed through surgical treatment, it can be clinically cured without affecting the survival time.
If the blockage is caused by cancer, such as cholangiocarcinoma, pancreatic head cancer or periampullary cancer, in this case, the survival period of the patient will be greatly affected, and the survival rate will be significantly reduced. However, if early detection and early treatment are possible, the survival rate can be improved.
If the bile duct obstruction is caused by congenital factors, as long as it is detected in time and treated as early as possible, it will not affect the survival rate in general.
