Evaluation of a vessel-sealing device for use in laparoscopic ovariectomy in mares.
OBJECTIVE
To evaluate a vessel-sealing instrument (LigaSure) as a method for hemostasis of the ovarian vasculature.


METHODS
Prospective study.


METHODS
Thirteen mares (8 experimental, 5 patients), aged 2 to 20 years and weighing 405 to 500 kg.


METHODS
Thirteen mares had standing bilateral laparoscopic ovariectomy using a vessel-sealing device (LigaSure) to provide hemostasis. Eight reproductively normal experimental mares were divided into 2 groups: 1 group was re-examined laparoscopically 72 hours and the other group 10 days after the initial standing laparoscopic ovariectomy. The vessel-sealing device uses high current and low voltage, along with pressure, to reorganize the collagen into a translucent seal to achieve hemostasis of the ovarian vasculature.


RESULTS
No major operative or postoperative complications were encountered. Complete hemostasis of the ovarian pedicle was accomplished. One mare had a fever for 24 hours' postoperatively; this responded to a single dose of flunixin meglumine.


CONCLUSIONS
The LigaSure appears to be a safe method for hemostasis of the ovarian vasculature.


CONCLUSIONS
Benefits of the LigaSure include no foreign material remaining in the abdomen and minimal to no need for surgical dissection before application. The LigaSure eliminates complications with potential ligature slippage and bleeding during dissection.
