Unilateral and bilateral laparoscopic ovariectomy in 157 mares: a retrospective multicenter study.
Abstract: To evaluate surgical techniques, perioperative complications and outcome of laparoscopic surgery for unilateral and bilateral ovariectomy in mares. Methods: Retrospective multicenter case series. Methods: Mares (n = 157). Methods: Indications for surgery were neutering, fertility problems, elimination of hormone-related abnormal behavior, ovarian tumors as well as nonregressive ovarian hematomas or cysts. Ovariectomy (n = 206) were performed by a standard laparoscopic procedure in 157 standing sedated mares. Dissection and hemostasis were achieved by using either (1) a linear stapling device, (2) bipolar electrosurgical instruments, with or without a modified Roeder knot, (3) a vessel-sealing system, or (4) a diode-laser with ligation. For some larger ovarian masses (>20 cm diameter), a 2-step surgical procedure was used with standing flank laparoscopic ovariectomy followed by ovarian retrieval through a median celiotomy. Surgical techniques, outcome, and perioperative complications of each method were recorded and analyzed. Results: Laparoscopic dissection of the ovary was accomplished in all mares. Because of the size of the ovarian tumor (n = 7) or in 1 mare with behavioral problems (n = 1), the dissected ovary was removed through a median celiotomy under general anesthesia. Seventeen mares (10.8%) developed postoperative complications (eg, incisional drainage, incisional infection, seroma formation, dehiscence, transient fever and mild abdominal discomfort). All mares with flank incisional problems had ovarian size >12 cm and in 15 (88%) of these mares electrosurgical instruments were used for mesovarial dissection. Conclusions: Laparoscopic ovariectomy in standing sedated mares provides good surgical access and is associated with low morbidity.

The research paper addresses the evaluation of surgical techniques, complications, and outcomes in laparoscopic ovariectomy (a surgical procedure to remove one or both ovaries) performed in 157 mares.
Research Methodology
- The authors adopted a retrospective multicenter case series design in evaluating the surgical techniques. The study participants were 157 mares.
- The surgical procedures carried out were done with various indications including neutering, fertility issues, removal of hormonal-related unusual behaviors, ovarian tumors, and nonregressive ovarian hematomas or cysts.
- The researchers performed 206 ovariectomies using a standard laparoscopic procedure. The mares were sedated and standing during the operation.
- The dissection and hemostasis were accomplished using a linear stapling device, bipolar electrosurgical instruments (with or without a modified Roeder knot), a vessel-sealing system, or a diode-laser with ligation.
- In cases of larger ovarian masses (over 20cm in diameter), a two-step surgical procedure was applied that entailed standing flank laparoscopic ovariectomy accompanied by ovarian retrieval through a median celiotomy.
Surgical Techniques, Outcome, and Complications
- All the surgical techniques, outcomes, and perioperative complications were precisely recorded and thoroughly analyzed.
- The study’s results indicate that all the mare subjects underwent successful laparoscopic dissection of their ovaries.
- In 8 cases, due to the size of the ovarian tumor or behavioral problems, it was necessary to remove the dissected ovary through a median celiotomy under general anesthesia.
- Approximately 10.8% (17) of the mare subjects experienced postoperative complications. These included incisional drainage, incisional infection, seroma formation, dehiscence, a temporary fever, and mild abdominal discomfort.
- Mares with flank incisional issues had ovarian sizes larger than 12 cm and in 15 of these cases, electrosurgical instruments were utilized for mesovarial dissection.
Research Conclusions
- The researchers concluded that laparoscopic ovariectomy in standing, sedated mares offers excellent surgical access and is associated with low morbidity.
