ABSTRACT
SUMMARY INTRODUCTION Liver biopsies such as tru-cut (sharp needle) and fine-needle aspiration cytology (FNAC) are the most commonly preferred techniques to detect the grade and stage of certain liver diseases. In this study, we aimed to compare the efficiency of USG-guided tru-cut biopsy and fine-needle aspiration cytology in an experimental alcoholic liver disease model. METHODS Thirty-six female Wistar albino rats, 4-6 months old, and weighing from 190 to 250 g, were used in this study. The animals were randomly divided into six equal groups G1 (control), G2 (tru-cut control), G3 (FNAC control), G4 (Alcoholic liver disease model), G5 (Alcoholic liver disease model + FNAC), and G6 (Alcoholic liver disease model + tru-cut biopsy). After a histopathological evaluation by light microscopy, the sensitivity, specificity, positive and negative predictive values of FNAC and tru-cut biopsy for the diagnosis of liver lesions were calculated. RESULTS No pathology was detected in G1 except for mild congestion. On the other hand, hepatocyte damage, periportal inflammation, congestion, and fatty changes were detected in all liver tissues of the alcoholic liver disease groups. The sensitivity of hepatocyte damage, inflammation, congestion, and fatty change parameters for FNAC were 33.3%, 80%, 0%, and 0%, respectively, while the sensitivity of the same variables for tru-cut were 66.7%, 40%, 100%, and 20%, respectively. DISCUSSION Both techniques were superior in some aspects. FNAC can be an attractive alternative to tru-cutbiopsy and applied in routine practice in the diagnosis of non-tumoral liver diseases.
RESUMO
RESUMO INTRODUÇÃO Biópsias hepáticas tais como por agulha tru-cut e por citologia aspirativa por agulha fina (CAAF) são as técnicas frequentemente preferidas para detectar o grau e o estágio de certas doenças hepáticas. Neste estudo, nosso objetivo foi comparar a eficiência da biopsia com agulha tru-cut guiada por ultrassom e a citologia aspirativa por agulha fina em um modelo experimental de doença hepática alcoólica. MÉTODOS Trinta e seis ratos Wistar albinos fêmeas, de 4 a 6 meses de idade e pesando entre 190 e 250g, foram utilizados neste estudo. Os animais foram divididos aleatoriamente em seis grupos G1 (controle), G2 (controle tru-cut), G3 (CAAF), G4 (modelo de doença hepática alcoólica), G5 (modelo de doença hepática alcoólica + CAAF) e G6 (modelo de doença hepática alcoólica + biópsia tru-cut). Após uma avaliação histopatológica por microscopia de luz, foram calculados a sensibilidade, especificidade e os valores preditivos positivos e negativos da CAAF e biópsia por tru-cut para o diagnóstico de lesões hepáticas. RESULTADOS Nenhuma patologia foi detectada no G1, apenas leve congestão. Por outro lado, detectamos danos nos hepatócitos, inflamação periportal, congestão e alterações nos ácidos graxos nos tecidos hepáticos de todos os grupos de doença hepática alcoólica. As sensibilidades encontradas para os danos nos hepatócitos, inflamação, congestão e alterações nos parâmetros de ácidos graxos para a CAAF foram 33,3%, 80%, 0% e 0%, respectivamente, enquanto que as sensibilidades das mesmas variáveis para o método tru-cut foram 66,7%, 40%, 100% e 20%, respectivamente. DISCUSSÃO Ambas as técnicas foram superiores em alguns aspectos. A CAAF pode ser uma alternativa atraente à biópsia por tru-cut e aplicada como prática de rotina no diagnóstico de doenças hepáticas não tumorais.
