Pediatric liver transplantation: fourteen years of experience at the children institute in São Paulo, Brazil.

This study reports the 14-year experience of a single center on 206 liver transplantations from living and cadaveric donors performed in 179 pediatric patients. Biliary atresia (57.2%) and fulminant hepatitis (9.8%) were the most frequent indications. The mean age of the recipients was 3 years, 7 months (9 months to 18 years) and mean weight was 14 kg (7 to 57 kg). The allografts were distributed as 82 (39.8%) whole cadaveric, 76 (36.9%) reduced-size cadaveric, 46 (22.3%) living donor liver transplants, and 2 (0.9%) ex situ split livers. The waiting periods were 25 days for living donors and 2.5 years for cadaveric donors (P <.001). Twenty-seven children were retransplanted with hepatic artery thrombosis the most frequent indication. The postoperative complications were: primary nonfunction (12.2%), biliary stenosis (28.8%), hepatic artery thrombosis (12.2%), portal vein stenosis (4.9%), hepatic vein stenosis (6.9%), and lymphoproliferative disorder (5.9%). The diagnosis of biliary stenosis was obtained by liver biopsy and transhepatic cholangiography and treated by balloon dilatation, although four children (3.9%) required a redo hepaticojejunostomy. The venous stenoses were percutaneously dilated with five-children (4.9%) requiring venous stents. The incidence of hepatic vein stenosis was 15.6% among living donor and 2.5% in cadaveric liver transplantation (P <.05). The overall 5-year patient and graft survivals were 70.2% and 65.1%. Liver transplantation provides excellent long-term survival. The use of grafts from living donors decreases the waiting periods but increases the incidence of hepatic vein stenosis.

[Extracorporeal membrane oxygenation (ECMO) in a neonate with respiratory distress due to meconium aspiration syndrome: Effect of the administration of exogenous surfactant] / Circulação extracorpórea prolongada (ECMO) em recém-nascido com insuficiência respiratória por Síndrome de Aspiração Meconial: efeitos da administração de surfactante exógeno.

OBJECTIVES: To present the clinical outcome of a newborn with severe respiratory distress secondary to meconium aspiration syndrome and treated by extracorporeal membrane oxygenation (ECMO); and to present the effect of the use of exogenous surfactant in this case and the cost of the procedure. METHODS: Case report of a newborn with meconium aspiration syndrome and treated at the neonatal ICU of the Instituto da Criança Prof. Pedro de Alcantara, Hospital das Clínicas of the Universidade de São Paulo. RRESULTS: ECMO was carried out for 5 days with no clinical or mechanical complications. On the 4th day of ECMO, we administered porcine exogenous surfactant; a significant improvement in lung compliance was observed and the newborn was decannulated shortly after that. Treatment costs were compatible with the situation of healthcare in Brazil for treatment of critically ill newborn patients. CONCLUSIONS: ECMO is indicated in cases of neonatal respiratory distress not responding to other treatments. The technique should be made available in neonatal Intensive Care Units (ICUs) of tertiary hospitals according to well-established protocols. The use of exogenous surfactant apparently allowed for earlier decannulation of the patient and should be considered in similar cases. The treatment costs do justify the organizing of ECMO teams in this type of ICUs.
