Summary
# Laparoscopic Ovariectomy in Mares: Evaluating the LigaSure Vessel-Sealing Device Standing laparoscopic ovariectomy remains a valuable surgical option for mares, but achieving reliable haemostasis of the ovarian vasculature without leaving foreign material in the abdomen has traditionally required careful ligation techniques. Researchers assessed whether the LigaSure vessel-sealing device—which uses high-current, low-voltage energy and mechanical pressure to reorganise collagen and create a tissue seal—could provide safe and effective haemostasis in 13 mares (8 experimental animals and 5 clinical patients aged 2–20 years). Complete haemostasis was achieved in all cases with no major operative or postoperative complications; only one mare developed a transient 24-hour fever responding to a single dose of flunixin meglumine. The device eliminated the need for extensive dissection before application and removed the risk of ligature slippage or bleeding during dissection, whilst leaving no foreign material within the peritoneal cavity. For practitioners performing standing laparoscopic ovariectomy, the LigaSure represents a technically straightforward alternative to traditional ligation methods, potentially reducing operative time and postoperative complication rates, though wider adoption should account for equipment costs and the requirement for specialised training.

Practical Takeaways
- •LigaSure provides reliable hemostasis for ovarian vessels in standing laparoscopic ovariectomy with no foreign material left behind, simplifying post-operative management
- •This technique reduces operative time and complexity compared to traditional ligation methods, making standing ovariectomy more accessible for practitioners with laparoscopic capability
- •Safety profile is excellent with minimal complications, though long-term follow-up in larger populations would strengthen confidence in routine clinical adoption
Key Findings
- •LigaSure vessel-sealing device achieved complete hemostasis of ovarian pedicles in all 13 mares undergoing standing laparoscopic ovariectomy
- •No major operative or postoperative complications were encountered across the study group
- •Follow-up laparoscopic examinations at 72 hours and 10 days confirmed sustained hemostasis without bleeding or seal failure
- •Device eliminated need for ligature placement and associated complications such as ligature slippage
