Abstract :
Background and type of study: Review of laparoscopic ovarian surgeries in mares
Objective: To describe the application and use of laparoscopy in ovarian removal surgeries in mares
Results: Ovariectomy in horses is performed for a variety of reasons. The most common reason is pathological removal of abnormal ovaries in the form of granulosa theca cell tumors. Various surgical approaches and amputation techniques have been developed for equine ovariectomy. The flank approach is preferred because of improved visibility, however, it is still difficult to remove the ovary without making large incisions. As a result, laparoscopic ovariectomy in the standing position has become the more common method of ovariectomy in mares. Advantages of laparoscopic techniques include reduced complications through complete visualization of the surgical field, minimal invasiveness, short recovery time with fewer postoperative complications, and improved cosmetic appearance of the surgical site. It also allows for ligation without damaging the vessels in the mesovarium. Concerns and limitations associated with laparoscopic techniques include the cost of specialized equipment, the need for high skill and the training required to perform them. It is true that lack of familiarity and skill can significantly increase the time of the procedure. Earlier return to sport is also possible after laparoscopic oophorectomy compared to colpotomy oophorectomy. Regardless of size, ovaries are successfully removed through small incisions (5-10 cm) without major complications and without cosmetic improvement of the surgical site. All sport horses return to their previous levels or higher, and most breeding mares successfully mate in the first season after surgery.
Conclusion: Large pathological ovaries can be easily removed by performing standing laparoscopic ovariectomy in mares. Laparoscopic ovariectomy in the standing position with a small flank incision is a safe and highly effective method for removing large pathological ovaries in mares which eliminates the need for general anesthesia or large incisions for the surgeon.
