OBJECTIVES: To present the experience with the first 12 living related liver transplants performed at Hospital Sírio-Libanês in São Paulo. METHODS: The donors were the fathers (6) and the mothers (6) with age ranging from 30 to 48 years. All candidates for donation were submitted to a full informed consent form, clinical and radiological evaluation and had blood withdrawn for autotransfusion. Recipient age ranged from 7 months to 10 years whereas recipient weight varied from 6.3 to 34 kg. Six patients were considered as high risk due to complications of advanced liver disease and were submitted to urgent transplantation. RESULTS: Mean donor hospital stay was 10 days with no mortality. Technical complications were observed in 4 recipients. Seven patients presented at least one episode of bacterial, viral or fungal infection. One or more biopsy proven rejection episodes were disclosed in 7 patients. Overall recipient survival was 67%, being 83% for elective cases and 50% for urgent cases. Long term follow up ranged from 8 to 25 months. Seven out of 8 survivors present excellent quality of life and normal liver function. The other patient is currently under reduced immunosuppression due to Epstein-Barr virus infection.CONCLUSIONS: These results demonstrate the safety and viability of living related liver transplantation which, in face of the current donor scarcity, should be considered as a valid option for the treatment of children with end stage liver disease.
