Resumo
Este estudo visou avaliar a eficácia do método de biópsia hepática laparoscópica por cauterização e estudar os seus efeitos no fígado de cães sadios. Além disso, procurou-se verificar as principais alterações hematológicas e bioquímicas-séricas relacionadas às funções hepáticas e averiguar a viabilidade dos fragmentos colhidos por exame de histopatologia. Para tanto, 21 cães clinicamente sadios pesando entre 10 e 15kg, foram separados em três grupos de sete animais cada grupo. As amostras foram retiradas da borda no lobo lateral esquerdo, utilizando-se pinça de biópsia conectada a eletrocautério na freqüência de 45W. Foram realizadas 42 biópsias hepáticas por laparoscopia nos 21 animais supra- referidos. No grupo I, colheu-se um fragmento hepático por animal. No grupo II, colheram-se dois fragmentos e no grupo III, colheram-se três fragmentos por animal. Os cães foram avaliados nos períodos pré, pós-operatório (tempos 4h e 6h) e aos 30 dias de evolução. Os resutados obtidos revelaram que não houve alterações hematológicas, bioquímicas e histopatológicas relacionadas à técnica. Não foram observadas alterações significativas nos parâmetros estudados, sugerindo que não ocorreram alterações hepáticas que comprometessem a função do órgão.
Hepatic biopsy was realized through laparoscopy with simultaneous cauterization in the present study, whose principal aim was to evaluate the efficacy of the applied method and to study its effects in the liver of healthy dogs. Furthermore, we tried to verify the main hematological and chemistry profile alterations related to the hepatic function, and to investigate the viability of the fragments collected by histopathology. To attain this objective, 21 clinically healthy dogs, weighing between 10 and 15kg were submitted to hepatic biopsy with forceps connected to the cautery. Cautery was performed by applying radiofrequency energy at 45 watts. Forty-two hepatic biopsies through laparoscopy were conducted in the animals. At group I one hepatic fragment per animal was collected, at group II two hepatic fragments per animal were collected, and at group III three fragments were collected. Hematocrit and alanine-aminotransferase measurements were employed to evaluate the animals at the pre-operative period, at four and six hour post-operative, and at day 30 post-operative. The results revealed that the procedure was safe and effective for hepatic biopsy in dogs. There were no clinical alterations related to the technique. The fragments collected were viable for histopathology. Hepatic biopsy through laparoscopy with simultaneous cauterization is an effective and usefull method in dogs.
