ABSTRACT

BACKGROUND:

Intestinal perforation (IP) after pediatric liver transplant (PLT) is an uncommon complication with high mortality reported. The aim of this study is to identify the risk factors and management of this complication. MATERIALS AND

METHODS:

Retrospective study of IP after PLT from January 2014 to October 2020.

RESULTS:

Four intestinal perforations were indentificated in 102 PLT (3,9%). Three patients with BA and one neonate with hemochromatosis (HC) presented this complication. The mean weight of patients with IP was 6.3± 2.5kg (3.1-9) and 19.9 ± 15.4kg for the rest (p< 0.05). All IP with BA had a previous laparotomy. Two living donors and two left lateral reduced liver were implanted. The diagnosis of intestinal perforation was done on day 11 ± 3.3 (8-15 days). Diagnosis was suspected with clinical and biological signs of perforation, CT scan confirmed the diagnosis in patiens with BA and by direct visualization through the mesh for temporary closure in the patient with hemocromatosis. Urgent laparotomy was performed. We identified three colonic perforations, all of them in BA patients and all repaired with direct suture. The patient with HC presented multiple perforations secondary to necrotizing enterocolitis requiring an ileostomy and finally died due to multiorgan failure.

CONCLUSION:

Intestinal perforation after PLT is an infrequent complication. Age, weight, previous laparotomy and BA could be risk factors for IP in PLT. Urgent laparotomy after diagnosis should be performed in order to reduce mortality. Isolated IP with adequate treatment might not affect long term outcomes after pediatric liver transplantation.
RESUMEN

INTRODUCCION:

La perforación intestinal (PI) tras trasplante hepático pediátrico (THP) es una complicación poco frecuente, pero con una elevada mortalidad. El objetivo de este estudio es identificar los factores de riesgo y el manejo de esta complicación. MATERIAL Y

METODOS:

Estudio retrospectivo de la PI tras THP entre enero de 2014 y octubre de 2020.

RESULTADOS:

Se hallaron 4 perforaciones intestinales en 102 THP (3,9%). Presentaron esta complicación 3 pacientes con atresia biliar (AB) y un neonato con hemocromatosis (HC). El peso medio de los pacientes con PI era de 6,3 ± 2,5 kg (3.1-9) y de 19,9 ± 15,4 kg en el caso del resto (p<0,05). Todos los pacientes con PI y AB habían sido sometidos previamente a laparotomía. Se implantaron 2 hígados de donantes vivos y 2 hígados laterales reducidos izquierdos. El diagnóstico de perforación intestinal se efectúo en el día 11 ± 3,3 (8-15 días), sospechándose con signos clínicos y biológicos de perforación, y confirmándose mediante escáner en los pacientes con AB y mediante visualización directa a través de la malla para el cierre temporal en el paciente con hemocromatosis. Se llevó a cabo laparotomía de urgencia. Se identificaron 3 perforaciones de colon, todas ellas en pacientes con AB y reparadas con sutura directa. El paciente con HC presentaba múltiples perforaciones secundarias a enterocolitis necrotizante que precisaron ileostomía, falleciendo finalmente como consecuencia de un fallo multiorgánico.

CONCLUSIONES:

La perforación intestinal tras THP es una complicación poco frecuente. La edad, el peso, las laparotomías previas y la AB podrían ser factores de riesgo de PI en el THP. Para reducir la mortalidad, es conveniente practicar una laparotomía de urgencia tras el diagnóstico. Una PI aislada con un adecuado tratamiento puede no influir en los resultados a largo plazo tras un trasplante hepático pediátrico.
