ContextLiver transplantation is one of the last viable resources for patients with end-stage liver disease. Many strategies are been used to improve the number of available organs and overcome waiting list delay. However, hepatic steatosis is one of the mainly concerns when organs are consider to transplantation due to it is importance as a risk factor for primary dysfunction. Surgeons play an important role to decide each organ will be accept or decline and its righteous allocation.ObjectiveRetrospectively evaluate the surgeon assessment of steatosis degree and its confrontation with further histopathologic findings.MethodsWe analyzed 117 patients underwent deceased liver transplantation for end-stage liver disease in University Hospital Walter Cantideo, Fortaleza, CE, Brazil. A matrix table was organized to estimate the categorical data observed. We clustered the subjects into mild (0%-30%) and moderate (30%-60%) steatosis degree under the clinical criteria of organ suitability for transplantation. We categorized the organs as suitable organ for transplant and as non-suitable organ for transplant. Evaluations between the two first assessments, before perfusion (pre-perfusion) vs biopsy findings and after perfusion vs biopsy findings observations were analyzed and also a comparison between pre-perfusion and after perfusion data was performed.ResultsOn the first assessment, we obtained a 93% of agreement (n = 109) between the two evaluations. On the second assessment, we had an 8% (n = 9) of mistaken allocation. Comparing the observation before (pre-perfusion) and after (after perfusion), we obtained a strong agreement between the surgeons.ConclusionsAlthough our experienced surgeon team, we have wrongly evaluated feasible organs for transplantation. Nonetheless, our faulty percentage is low comparing to worldwide percentage.
ContextoO transplante ortotópico de fígado é considerado um dos últimos recursos terapêuticos viáveis para os pacientes hepatopatas, em estágio terminal da doença. Muitas estratégias têm sido usadas para aumentar o número de órgãos disponíveis e diminuir a demora em lista de espera. No entanto, a presença de esteatose hepática é uma das principais limitações quanto ao uso de órgãos para transplante, devido a sua importância como relevante fator de risco para disfunção primária pós-transplante. Neste cenário, a avaliação do órgão pelo cirurgião, no momento da captação no doador, é de grande importância para a correta alocação do mesmo.ObjetivoAvaliar retrospectivamente o grau de esteatose estabelecido pelo cirurgião e confrontar estes dados com os achados histopatológicos da biopsia.MétodosAnalisaram-se 117 pacientes hepatopatas terminais sub-metidos ao transplante de fígado no Hospital Universitário Walter Cantídeo, Fortaleza, CE. Uma tabela matriz foi organizada para avaliação dos dados categóricos observados.
