Bilateral laparoscopic ovariectomy in standing mares: 22 cases.
Abstract: To describe a technique for laparoscopic bilateral ovariectomy in standing mares and report the outcome of 22 clinical cases. Methods: Prospective study. Methods: A total of 22 mares between 4 and 23 years of age, weighing between 360 and 600 kg. Methods: Mares with normal ovaries, as determined by palpation per rectum, were restrained in standing stocks and sedated with detomidine (0.01 to 0.02 mg/kg intravenously [i.v.]) and butorphanol (0.01 to 0.02 mg/kg i.v.). The laparoscope and instrument insertion sites were infiltrated with 2% lidocaine before incision. One laparoscope portal and two instrument portals were located in each paralumbar fossa. Ovariectomy was accomplished by intracorporeal dissection and ligation of the ovarian pedicles. The two instrument portals in each flank were ultimately connected resulting in a 4 to 5 cm laparotomy to facilitate ovarian removal. Results: No major operative or postoperative complications occurred. Minor complications included incomplete hemostasis of an ovarian pedicle with a single ligature (three mares), transient inappetence, pyrexia and incisional infection. Owner satisfaction and cosmetic results were considered excellent. Conclusions: Standing laparoscopic ovariectomy appears to eliminate many of the potential complications associated with traditional surgical methods for ovariectomy and avoids the risk of general anesthesia. Conclusions: This technique requires minimal laparoscopic instrumentation and will provide surgeons with an alternative approach for bilateral ovariectomy in mares.

This research studies a method of laparoscopic bilateral ovariectomy in standing mares, with results from 22 cases showing no major complications, thus suggesting that this method can be an alternative to traditional surgical methods and evade the risks of general anesthesia.
Objective and Methodology
- The manuscript outlines a probed technique for performing laparoscopic bilateral ovariectomy in standing mares. It proceeds to report the outcomes of 22 clinical cases where this procedure was executed.
- The study is projected and includes 22 mares that ranged in age from 4 to 23 years and weighed between 360 and 600 kilograms.
- The specific mares selected for the study exhibited normal ovaries, as verified through rectal palpation. The mares were restrained in an upright stance and sedated with detomidine and butorphanol administered intravenously.
- To prepare for incision, the laparoscope and instrument overlay sites were infiltrated with 2% lidocaine.
Procedure and Complications
- One portal for the laparoscope and two portals for other instruments were created in every paralumbar fossa for the surgery.
- The ovarian pedicles were dissected and ligated from inside the body to perform the ovariectomy. The two portals for the instrument in each flank were eventually linked, resulting in a 4 to 5cm laparotomy to aid in the removal of the ovary.
- Despite some complications of incomplete hemostasis of an ovarian pedicle with a single ligature (occurring in three mares) and minor issues such as transient loss of appetite, fever, and incisional infection, there were no major operative or postoperative complications reported.
Conclusion
- The reported owner satisfaction and cosmetic results were considered excellent. This indicates a high acceptance rate for the procedure.
- Performing laparoscopic ovariectomy in mares while they are standing appears to eliminate many of the potential complications traditionally associated with surgical methods for ovariectomy. Furthermore, this technique has been found to avoid the need for general anesthesia.
- With its lesser need for laparoscopic instrumentation, this technique offers surgeons an alternative approach for executing bilateral ovariectomy in mares.
