    Abstract:
    AIM: To compare the outcomes of pediatric patients weighing less than or more than 10 kg who underwent liver transplantation. METHODS: Data for 196 pediatric patients who underwent living donor liver transplantation between June 1994 and February 2011 were reviewed retrospectively. The information for each patient was anonymized and de-identified before analysis. The data included information regarding the pre-transplant conditions, intraoperative fluid replacement and outcomes for each patient. The 196 patients were divided into two groups: those with body weights of less than 10 kg were included in group 1 (G1; n = 101), while those with body weights of more than 10 kg were included in group 2 (G2; n = 95). For each group, the patients' ages, body weights, heights, pediatric end stage liver disease scores, anesthesia times, and warm and cold ischemic times were analyzed. In addition, between-group comparisons were also made. Mann-Whitney U tests were used to compare all the variables except for complications and survival rates, which were analyzed using χ(2) tests and Kaplan-Meier tests, respectively. RESULTS: The general medical conditions of the G1 patients were worse than those of the G2 patients, as shown by the higher pediatric end stage liver disease scores and poorer Z-scores. In addition, the pre-operative Hb and serum albumin levels were all lower for the G1 patients than for the G2 patients. The G1 patients also had significantly more intraoperative blood loss than the G2 patients. In addition, the intraoperative fluid requirements for the G1 patients, including leukocyte poor red blood cell transfusions, 5% albumin infusions and crystalloid infusions, were significantly higher than those for the G2 patients. The risk of intraoperative portal vein thrombosis was higher for the patients in G1 than for those in G2. However, the one-year survival rates (95.9% and 96.8% for G1 and G2, respectively) and three-year survival rates (94.9% and 94.6% for G1 and G2, respectively) for both groups were similar. CONCLUSION: Patients weighing less than 10 kg typically have poorer conditions, but their survival rates are comparable to those of children weighing more than 10 kg.
