Thank you, Drs M. Srinivas and M. Rela, for your insightful comments on our publication “Outcomes of Highly Selected Live Donors With a Future Liver Remnant Less Than or Equal to 30%: A Matched-Cohort Study.”1

We agree with Drs Srinivas and Rela when they say that donor safety must be the cornerstone of live donation. In fact, our practice with regard to donor selection and their outcomes in our center is previously published demonstrating safety.2,3 In this study, we state that donors with remnant <30% should be considered only in very selected cases. Therefore, we also agree with the authors in that regard.

The main message in this study is that a solid number of 30% could be safely relaxed in selected cases after (1) thorough evaluation by experienced live donation surgeons and (2) the referred donor is the only donor available for a specific recipient. In our study, therefore, rather than pushing to the edge, we push the envelope against dogmatic and arbitrary thresholds—so common in the surgical field—that could prevent saving a recipient life and keeping the donor safe.

Again, thank you for your letter.
