ABSTRACT
ABSTRACT

Background:

The outcome of the patients after liver transplant is complex and to characterize the risk for complications is not always easy. In this context, the hepatic post-reperfusion biopsy is capable of portraying alterations of prognostic importance.

Aim:

To compare the results of liver transplantation, correlating the different histologic features of the hepatic post-reperfusion biopsy with graft dysfunction, primary non-function and patient survival in the first year after transplantation.

Method:

From the 377 transplants performed from 1996 to 2008, 164 patients were selected. Medical records were reviewed and the following clinical outcomes were registered mortality in 1, 3, 6 and 12 months, graft dysfunction in varied degrees and primary graft non-function. The post-reperfusion biopsies had been examined by a blinded pathologist for the outcomes. The following histological variables had been evaluated ischemic alterations, congestion, steatosis, neutrophilic exudate, monomorphonuclear infiltrate and necrosis.

Results:

The variables associated with increased mortality were steatosis (p=0.02209), monomorphonuclear infiltrate (p=0.03935) and necrosis (p<0.00001). The neutrophilic exudate reduced mortality in this study (p=0.00659). The primary non-function showed significant association (p<0.05) with the necrosis, steatosis and the monomorphonuclear infiltrate.

Conclusion:

Post-reperfusion biopsy is useful tool to foresee complications after liver transplant.
RESUMO
RESUMO Racional A evolução dos pacientes após transplante hepático é complexa e caracterizar o risco para complicações nem sempre é fácil. Nesse contexto, a biópsia hepática pós-reperfusão é capaz de retratar alterações de importância prognóstica.

Objetivo:

Avaliar os resultados no primeiro ano após transplante hepático, correlacionando as alterações histológicas à biópsia hepática pós-reperfusão com a sobrevida, a disfunção e o não-funcionamento primário do enxerto.

Método:

Dos 377 transplantes ocorridos de 1996 a 2008, 164 pacientes foram selecionados para estudo. Os seguintes desfechos clínicos foram registrados mortalidade em 1, 3, 6 e 12 meses, disfunção do enxerto em graus variados e o não-funcionamento primário do enxerto. As biópsias pós-reperfusão foram examinadas por um patologista sem conhecimento dos resultados. As seguintes variáveis histológicas foram avaliadas alterações isquêmicas, congestão, esteatose, exsudato neutrofílico, infiltrado monomorfonuclear e necrose.

Resultados:

As variáveis associadas com aumento da mortalidade foram esteatose (p=0.02209), infiltrado monomorfonuclear (p=0.03935) e necrose (p<0.00001). O infiltrado neutrofílico reduziu a mortalidade neste estudo (p=0.00659). O não-funcionamento primário do enxerto mostrou associação significativa (p<0.05) com a necrose, a esteatose e com o infiltrado monomorfonuclear.

Conclusão:

A biópsia hepática pós-reperfusão é ferramenta útil em prever complicações após o transplante hepático.
