Current status of adult liver transplantation: utilization of living donor versus deceased donor graft.

Abstract

This article will summarize prior and recent studies comparing outcomes between living donor and deceased donor liver transplantation (LT) in adults and provide a rationale and framework for expanding living donor liver transplantation (LDLT) in Western countries to address the growing critical organ shortage. There is a growing body of evidence demonstrating superior survival outcomes in LDLT in addition to a multitude of other advantages including shorter cold ischemia times, opportunity for pretransplant medical optimization, and expansion of transplant eligibility. Additionally, these outcomes continue to improve with center volume and experience. LDLT in adults emerged in response to an effective donor organ shortage created by the critical discrepancy between donor graft supply and demand. Overcoming this organ shortage and an increasing waitlist mortality requires a liver transplant framework that fully integrates LDLT into liver disease management although continuing to fully maximize deceased donor graft utilization at experience, capable centers. Optimizing both living and deceased donor graft utilization will drastically increase patients' access to LT.
