Life expectancy after pancreaticoduodenectomy should be judged according to the cause of the operation. Survival time varies according to the cause, life expectancy for benign diseases can be no different from normal people, and the 5-year survival rate for malignant diseases varies according to the primary disease.
1. If the cause of pancreaticoduodenectomy is benign, the patient’s survival is expected to be the same as that of a normal person, and the life expectancy is usually not affected too much.
2. If the cause of the operation is malignant, such as pancreatic cancer, the prognosis of the patient is usually poor, with a 5-year survival rate of less than 5%; if the operation is performed for duodenal cancer or bile duct cancer, the prognosis is usually better, with a 5-year survival rate of 50-70%.
In addition to the cause of the disease, postoperative care and treatment are also very critical, and the life expectancy is longer when there are no postoperative complications and the patient’s general condition is good.
