It is difficult to perform a comparison of the outcomes in the published literature due to the heterogeneity in practice of LDLT versus DDLT around the world. It all comes down to context and hence the availability of donor livers via either route. The HongKong liver transplant programme does publish outcome data for both LDLT and DDLT. Look for publications fro Albert C Chan or otherwise look up either ST Fan or CM Lo on Medline.
