A question that many patients and families often ask is: Which is better, a cadaveric liver transplant or a living liver transplant? Is there any difference? For patients who need liver transplantation for liver failure, the purpose of liver transplantation is to surgically implant a new liver, which will replace the original diseased liver to perform its function. This can be roughly calculated from the height and weight data, which means that the new liver implanted should not be smaller than this number in order to provide life-sustaining relief, which is also required for cadaveric liver transplantation, and the size of the cadaveric liver can basically meet this requirement. As the donor liver is taken from the patient’s relatives, a rough estimation of height and weight data is not enough. Before surgery, the volume and weight of the entire liver should be calculated by computed tomography (CT), and the volume and weight of the right half and left half of the liver should be calculated according to the condition of the middle hepatic vein. A living liver transplant can only be performed if the patient’s recovery needs can be met. As long as these conditions are perfectly met, a living liver transplant can be performed. Therefore, living liver transplantation and cadaveric liver transplantation can be equally useful for patients to achieve a cure for critical liver disease. The newly implanted part of the liver will grow gradually in the patient’s body, and after our long-term observation of all the nearly 200 patients who underwent living liver transplantation, the new liver grew to 70% of the size of the original liver in 1 month after surgery, and to more than 90% of the original liver in 3 months; the relatives of the donor liver, after hepatic resection of the donor part of the liver, their remaining liver tissue also undergoes the same growth process as the patient who received their part of the liver The patient grows to its original size in the same time and process. Both transplantation methods, therefore, achieve the same goal.
