Healthy Spouses can be Considered as Living Liver Donors.

Background: Spousal donors have gradually been accepted as an alternative living liver donors to alleviate the organ shortage and prevent donations from children. No information is available regarding the effects of spousal donation on donor safety and recipient outcomes. Our purpose in this study was to determine how spousal liver grafts in living donor liver transplantation (LDLT) affect donor safety and recipient outcomes compared with those of LDLT from children.

Methods: We retrospectively analyzed 656 patients, including spouses and children, who underwent a right or extended right hepatectomy for living liver donation between January 2009 and December 2018.

Results: Spouses represented 18.8% (n = 123) of living liver donors. Female donors comprised 78.9% (n = 97) of spousal donors, and the proportion of male donors in the children group was 72.6% (n = 387). The mean donor operation time of the spousal group was shorter than that of the children group (330 min vs. 358 min; P = 0.011), and the complication rate in the spousal group was lower than that in the children group (12.2% vs. 22.9%; P = 0.006). However, there were no differences in severe complication rates, hospitalization, or liver function tests between the 2 groups at 3 months after donor surgery. The overall survival of recipients in the spousal group was not reduced compared to that of recipients in the children group.

Conclusion: The present study suggests that, with careful selection, spousal donation is feasible and safe in LDLT.
