Single Center Long-Term Results of Pediatric Liver Transplantation.

OBJECTIVES

Liver replacement continues to be the only definitive mode of therapy for children with end-stage liver disease. However, it remains challenging because of the rare donor organs, complex surgical demands, and the necessity to prevent long-term complications. Our objectives were to analyze 16 years of experience in the Shiraz University Organ Transplant Center.

MATERIALS AND METHODS

We retrospectively analyzed the records of 752 patients (< 18 years old) who underwent orthotopic liver transplant at our center over a 16-year period. Mean age was 90 months, and male-to-female ratio was 1.25. Of the 752 transplants, 354 were whole organs, 311 were from living related donors, and 87 were in situ split liver allografts. Patient and graft survival rates were determined at 1, 3, and 5 years, and results between groups were compared.

RESULTS

Overall mortality was 31.8%. The 1-, 3-, and 5-year patient survival rates were 77%, 69%, and 66%, respectively, whereas the respective graft survival rates were 75%, 68%, and 65%. We observed significant differences in survival according to graft type (log-rank test, P < .001). We also observed significant differences in survival probabilities according to age (log-rank test, P < .001). Cox regression was used to simultaneously analyze effects of age and graft type on survival. Both graft type and age significantly affected survival (P < .001). The 1-, 3, and 5-year survival rates for patients having whole organ transplants were 88%, 81%, and 78%. Patients who received living donor grafts had respective survival rates of 66%, 60%, and 58%, with rates of 65%, 47%, and 47% for patients who received split grafts.

CONCLUSIONS

Our results were similar to those observed in the literature in terms of indication for transplant and posttransplant survival.
