Alterações bioquímicas e morfológicas após anastomose porto-cava e hepatectomia parcial: estudo experimental em cães Biochemical and morphological alterations after portocaval shunt and partial hepatectomy: experimental study in dogs

Abstract

OBJETIVO: Estudar os efeitos da anastomose porto-cava sobre a morfologia e bioquímica do fígado de cães. MÉTODOS: Vinte animais foram divididos em 2 grupos: o Grupo I foi submetido à hepatectomia parcial de 28,7% e o Grupo II, à hepatectomia parcial associada à derivação porto-cava. Os parâmetros analisados foram: peso corpóreo, colesterol e triglicérides plasmáticos, lipídios e glicogênio hepáticos e índice ponderal de regeneração hepática. Os dados foram analisados no pré-operatório e no 30° dia do pós-operatório. RESULTADOS: No Grupo I, apenas os lipídios hepáticos estavam significativamente elevados 30 dias após a cirurgia. No Grupo II, o colesterol plasmático e o glicogênio hepático apresentaram redução no pós-operatório, enquanto os lipídios hepáticos estavam significativamente elevados. Comparando-se os 2 grupos, houve diferença estatisticamente significativa nos valores do colesterol plasmático, do glicogênio e do índice de regeneraçãohepática. CONCLUSÃO: A anastomose porto-cava causa prejuízos morfológicos e bioquímicos significativos ao fígado, além de redução significativa do peso corpóreo.PURPOSE: The aim of this study was to assess the effect of portocaval shunt on liver biochemical and morphological aspects in dogs. METHODS: Twenty animals were divided into 2 groups: Group I was submitted to 28.7% partial hepatectomy and Group II underwent partial hepatectomy associated with portocaval shunt. The data analyzed were: body weight, serum cholesterol and triglyceride, hepatic lipids and glycogen and liver regeneration index. All these data were measured preoperatively and 30 days after surgery. RESULTS: In Group I, only hepatic lipids levels were statistically increased post-operatively. In Group II, serum cholesterol and hepatic glycogen values were reduced while hepatic lipids levels were increased 30 days after surgery. When both groups were compared to each other, serum cholesterol, hepatic glycogen and liver regeneration index showed statistically significant difference. CONCLUSION: Portocaval shunt causes morphological and biochemical impairment of the liver as well as reduction of body weight.
