The survival of pancreatic resection patients is related to the primary disease. The life expectancy of patients with benign lesions is not affected, and the specific survival of patients with malignant lesions is related to the degree of malignancy of the lesions and the treatment. The main function of the pancreas is the secretion function, such as insulin and glucagon. After islet removal, exogenous insulin and glucagon can be supplemented or even transplanted into the islet. If the islet is removed because of benign islet lesions, the life expectancy of the patient is not affected. The survival of patients with malignant islet tumors after islet removal is related to the nature of the lesion, whether metastasis occurs and the treatment, for example, the median survival time after palliative surgery for pancreatic head cancer is 7 months; the median survival time after radical surgery can be 18-20 months. Patients with pancreatic lesions, especially those with malignant lesions, are usually found to be at an advanced stage, and treatment is not effective; therefore, regular medical checkups are recommended for early detection and early treatment.
