Evaluation of creatine kinase (CK) and aspartate aminotransferase (AST) activities after laparoscopic or conventional ovariectomy in queens.

Creatine kinase (CK) and aspartate aminotransferase (AST) are mainly muscle-specific enzymes, which can be associated with muscle tissue damage. The aim of this study was to assess the activities of CK and AST during the postoperative period, after conventional (G1) and videolaparoscopic ovariectomy (G2), in queens. A further group (G3) was subjected to anaesthesia only. Results demonstrate that there were significant differences between groups. The highest levels of CK were recorded in G1, however at a confidence level of p<0.05 there was no significant difference between groups during the first 6 hours after surgery. A significant (p<0.05) increase of CK values was identified between 0 h and 3 h in both groups (G1 and G2). Regarding AST activity there was no significant variation between groups, but again there was a significant difference between values at 0 h and 3h after surgery. In conclusion, ovariectomy performed by videolaparoscopy seems to cause less muscle damage when compared to the conventional method.
