ABSTRACT
Living donor liver transplantation (LDLT) was first performed in the US in 1989, primarily benefiting pediatric patients. Its adoption for adults faced setbacks after a donor death in 2001, causing widespread risk aversion. Despite ethical justification and demonstrated safety, LDLT remains underutilized, with fewer than 10% of liver transplants being LDLT. Recent trends indicate improved access to deceased donor liver transplantation (DDLT) due to increased organ donation and technological advances like Normothermic Regional Perfusion (NRP). However, LDLT remains critical, especially for pediatric patients and specific adult populations who benefit significantly from it. Barriers to LDLT include public and clinician apprehensions about donor risks, despite studies showing low-complication rates. Non-directed donations and broader social media engagement have increased donor pools, though the volume of LDLT in the US remains lower than in Asia due to limited training and experience. The A2ALL consortium has been pivotal in studying LDLT safety and outcomes. Currently, around 40 US centers perform LDLT, with high-volume centers leading by example. Training paradigms for LDLT are evolving, with initiatives like the ASTS LDLT master class aiming to enhance surgical expertise. While LDLT is embedded in US liver-transplant practices, its expansion is hampered by risk aversion and the availability of DDLT. Nonetheless, LDLT is essential for addressing the supply-demand mismatch in liver transplantation.
