The advantage of liver transplantation is that if the transplantation is successful, the patient can have a longer survival period; the disadvantage is that complications and postoperative rejection reactions may occur. 1. Advantages: For patients with advanced cirrhosis, liver failure and some liver cancer patients, liver transplantation can give them a longer survival period and significantly improve their quality of life. 2. Disadvantages: Liver transplantation is a relatively high-risk surgical procedure, which may result in hemorrhage during the operation, complications related to vascular and bile duct suturing and rejection reactions after the operation, and serious infections may occur. Patients taking anti-rejection drugs for a long period of time can also increase the risk of infection and even malignancy. There is also a certain chance of recurrence of the primary disease after liver transplantation. Therefore, a decision on whether to transplant must be made after a detailed evaluation by a liver transplant specialist.
