Liver is an important digestive organ in human body, but it is impossible to infer the specific survival period of the patient based on liver resection alone, and it is necessary to further combine with the reason of liver resection, the size of liver resection and the postoperative recovery of the patient to make a comprehensive judgment. The liver has a strong self-regeneration ability, and liver resection is usually necessary in cases such as liver tumor disease, liver trauma, and infectious diseases of the liver that are difficult to be cured by internal medicine. Liver resection carries certain risks and does not guarantee a cure. How long a patient can live after liver resection still needs to be judged in light of the patient’s condition and recovery. When a doctor recommends liver resection, he or she has usually evaluated the benefits and possible risks of the surgery, and then formulated a treatment plan that is beneficial to the patient’s health. Patients are advised to cooperate actively in an effort to control the further progression of the disease.
