Ethical issues in living donor liver transplantation.
The cadaveric organ shortage and the high mortality rate while patients wait for an organ have driven the medical community to develop alternative strategies for treating patients with end-stage liver disease. Adult living donor liver transplantation (ALDT) has evolved in response to the cadaveric organ shortage. Although there are benefits for recipients of ALDT, donors may incur substantial risk, including death. In contrast to pediatric living donation, in which the left lateral segment of the liver is resected from a donor, ALDT generally requires right hepatectomy, which is associated with greater morbidity and mortality. Because ALDT places a healthy individual at risk for substantial morbidity and mortality, debate over the ethics of this procedure is ongoing. Two donor deaths have occurred in the United States, adding to the concern over donor safety. Despite the risks associated with ALDT, many individuals elect to proceed with living donation with the hope of improving the life of a relative or friend. When considering whether we as a society should support and encourage ALDT, we should examine the perspective of the donor, recipient, and medical community as well. The medical community has an obligation to study carefully the risks and outcomes associated with ALDT so that we can deliver the highest quality of care that is not at the expense of healthy individuals.
