It is not possible to accurately estimate how long pancreatic cancer can live after bile-intestinal anastomosis, and the survival time of different patients with different disease conditions is different. Different patients have different degrees of pancreatic cancer disease development, their survival time is different, the specific can live a few years, depending on the patient’s specific circumstances, can not be generalized. Pancreatic cancer is a kind of malignant tumor, if biliary anastomosis surgery is performed in the early stage of the disease, the survival time after surgery is longer, some patients are in the advanced stage of the cancer, the survival time of this kind of patients after biliary anastomosis surgery is prolonged, but the survival time is shorter compared with that of early stage of the population. After the biliary anastomosis surgery, patients should follow the doctor’s instructions to fast and drink, to ensure that the drainage tube is open, usually after ventilation patients can eat fluids and low-fat food. It is recommended that patients should actively cooperate with the treatment after the operation and follow the doctor’s instructions to improve the quality of survival and prolong the life cycle.
