Abstract
Orchiectomy is often employed in zootechnical activities with the main objective of carcass improvement; therefore, the search for alternatives that minimize surgical trauma, operative time and mainly decrease operating costs is pertinent. The nylon clamp is a tensile strength device, well tolerated by the body and inexpensive. It has been used as a hemostatic method in several surgical procedures. The aim of this study was to evaluate the operability and functionality of this device for the preliminary hemostasis of the spermatic cord in the open orchiectomy, comparing it to the surgical nylon thread. Twenty male pigs were divided into 2 experimental groups: GI (clamp - 10 animals) and GII (surgical nylon thread - 10 animals). The surgical time, the degree of hemostasis, the size of the incision, the presence or absence of edema and secretions, besides the weight gain were evaluated. For analysis of inflammatory response, fibrinogen was assessed. Compared to surgical nylon, the clamps presented advantages over surgical time and blood loss. It was concluded that the use of nylon clamps for hemostasis of the spermatic cords of pigs submitted to orchiectomies reduced the total time of surgeries, as well as hemorrhages, when compared to hemostasis with nylon thread. Furthermore, weight gain and induction of inflammatory response were not influenced by the hemostasis method used.
