Background: Retransplantation of the liver is required for several complications of primary grafting, such as primary allograft non-function, hepatic artery thrombosis, biliary problems, or chronic ductopenic rejection. Surgeons usually take regrafting as the only pathway to treat those patients who are considered to have a poor outcome after the first operation. Whether the retransplantation is early or late, further attempts at rescue with a second or more grafts are associated with higher mortality and morbidity. However, retransplantation plays a role in improving survival of the patients. Therefore, it is necessary to summarize the experiences in liver retransplantation, as well as the factors influencing operative effects.
Method: The clinical data of 8 patients who received liver retransplantation in our center were analyzed retrospectively.
Results: Complications of the biliary tract occurred in 5 of the 8 patients, chronic rejection in 2, and embolism in the hepatic artery in 1. Infections occurred in 7 patients before engraftment. Patient 1 had developed renal failure before the surgery, and he died of severe infection and multi-organ failure after transplantation. Patient 4 had a massive hemorrhage during the operation and also died of multi-organ failure after transplantation. Patient 7 developed intracranial hemorrhage and abdominal infection and died soon after transplantation. The other 5 patients recovered and discharged from the hospital.
Conclusions: Liver retransplantation is the only measure that can be taken to save the lives of patients whose liver allograft fails to function. It is very important that the indications and time of retransplantation are carefully selected. Factors leading to harmful effects on retransplantation include the preoperative condition of the recipient, a difficult and prolonged operation, massive hemorrhage during the operation, and severe complications after the surgery.
