Core Tip
Core Tip: Living donor liver transplantation is an established modality in expanding the donor pool but is limited by donor safety concerns and recipient and graft outcomes due to high prevalence of hepatic steatosis in obese or overweight donors. Weight loss is known to improve or resolve steatosis and help convert marginal donors to low-risk donors in a small series of studies. Our meta-analysis demonstrates that short term weight loss intervention, is feasible and safe in significantly reducing hepatic steatosis in living liver donors undergoing donor evaluation and has the potential to safely expand the donor pool.
