Evaluation of a vessel-sealing device for use in laparoscopic ovariectomy in mares.
Abstract: 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.

The study focuses on evaluating the efficiency of a vessel-sealing instrument (LigaSure) for halting blood flow (hemostasis) of the ovarian vasculature during laparoscopic ovariectomy (ovary removal) in mares. The results showed that the device was both safe and reliable for achieving complete hemostasis without major operative or postoperative complications.
Methods
- The study was a prospective study involving thirteen mares that were between 2 to 20 years old and weighed between 405 to 500 kg.
- These mares underwent a standing bilateral laparoscopic ovariectomy procedure where the LigaSure device was used for hemostasis of the ovarian vasculature.
- Eight of these mares, which were reproductively normal, were separated into two groups for further evaluation. One group was reevaluated through laparoscopy 72 hours after the ovariectomy and the other group 10 days later.
- The LigaSure device works by using high electric current and low voltage, along with pressure, to rearrange the collagen into a clear seal for achieving hemostasis.
Results
- No major operative or postoperative complications were experienced suggesting the safety of the procedure.
- The researchers achieved complete hemostasis of the ovarian pedicle which indicates the efficacy of the LigaSure device.
- Following the surgery, only one mare had a fever for 24 hours but recovered after a single dose of flunixin meglumine (a nonsteroidal anti-inflammatory drug).
Conclusions
- The LigaSure appears to be a safe method for securing hemostasis during laparoscopic ovariectomy.
- The benefits of LigaSure include: no foreign material left in the abdomen which lowers the risk of complications and little to no need for surgical dissection before its application.
- The LigaSure device removes the risk of complications related to potential ligature slippage and bleeding during dissection.
