Multivisceral Transplant, The Prince Charles Hospital Experience

Abstract

Background: Multi-visceral organ transplant is uncommon. As a result of the rarity of these surgeries, there are limited studies, making it difficult to interpret outcomes and identify specific patient complications. We aim to assess the indications for multi-organ transplant, the time on the wait-list and evaluate outcomes including patient survival, graft survival and postoperative complications in an Australian context.

Methods: Patients undergoing multi-organ transplant from 1993 to 2018 at The Prince Charles Hospital, Brisbane, Australia were retrospectively reviewed, looking at baseline characteristics and post-transplant morbidity, mortality and graft survival.

Results: A total of 37 patients were included in the study, comprising 22 heart-lung transplants, eight heart-kidney transplants and seven heart-lung-liver transplants. There were six domino heart transplants performed, all in the heart-lung-liver transplant group. The mean age at transplant was 37 years and the mean wait-list time was 10 months. One patient, receiving a heart-lung transplant, required re-transplantation (bilateral lung) at 3 years. One-year (1-year) survival was 91% for heart-lung transplants, 86% for heart-lung-liver transplants and 87.5% for heart-kidney transplants. Five- and ten-year (5- and 10-year) survival was 79% for both in heart-lung transplant, 43% and 29% for heart-lung-liver transplant and 87.5% for both in heart-kidney transplant.

Conclusion: Patients undergoing multi-organ transplant at our unit had long-term survival and organ function comparable to international data. In addition, waitlist time for multi-organ transplant was not found to be excessive.
