Objectives: This study aims to investigate postdonation outcomes of adult living donor liver transplantation donors and remnant liver regeneration in different graft types. Methods: A total of 236 adult living donor liver transplantation donors were classified into different groups: donors with <35% remnant liver volume (group A; n = 56) and donors with remnant liver volume ≥35% (group B, n = 180); left lobe grafts (LLG group; n = 98) including middle hepatic vein (MHV) and right lobe grafts (RLG group; n = 138) without MHV. The 98 LLG group donors were further classified into 2 subgroups based on hepatic venous drainage patterns: MHV-dominant (n = 20) and non-MHV-dominant (n = 78). The demographic data, postoperative laboratory data, complications, graft weight, remnant liver volume, remnant liver growth rate, and remnant liver regeneration rate (RLRR) after partial liver donation were analyzed. Results: The postoperative aspartate aminotransferase, alanine aminotransferase, total bilirubin, intensive care unit stays, and hospitalization stays were higher in A and RLG group donors. All the donor complications in our series were minor complications. The postoperative complication rate was higher in the A and RLG group, but failed to reach statistical significance. There was no significant difference in RLRR between the RLG/LLG and A/B groups. However, the MHV-dominant group had significantly lower RLRR than the non-MHV-dominant group (P <.05). Conclusions: Small remnant liver volume donors (<35% remnant liver) have higher risks of developing postdonation minor complications. Left lobe liver donation in MHV-dominant donor candidates are a major concern.
