Abstract

FANTINATTI, Alexandra Pinheiro et al. Laparoscopy hepatic biopsy through cauterization. Cienc. Rural [online]. 2003, vol.33, n.4, pp.703-707. ISSN 0103-8478.  http://dx.doi.org/10.1590/S0103-84782003000400019.

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.
