“…The surgical times observed in this study were similar to those observed with previous laparoscopic ovariectomy techniques. The duration of bilateral laparoscopic ovariectomy performed through bilateral incisions range from 102 to 128 min (mean or median), when a vessel sealing device similar to ours was used . The mean surgical time of the left paralumbar ovariectomy was 76 minutes, gradually decreasing throughout the study.…”

“…The postoperative complications encountered in this case series consisted of fever, mild colic, and incisional swelling. These complications are commonly reported after laparoscopic ovariectomy in horses and typically resolve with minor treatment, and without long‐term complication . A larger prospective study comparing unilateral and bilateral techniques would be necessary to investigate the relative number of complications and compare the outcomes of both procedures.…”

“…Minimally invasive standing laparoscopy is a common and accepted technique for ovariectomy in the mare . Most laparoscopic bilateral ovariectomies require incisions in both paralumbar fossae, with 2‐3 portals per paralumbar fossa . Restricting the number and location of laparoscopic portals within a single paralumbar fossa could minimize surgical morbidity in mares undergoing elective ovariectomy.…”

Objective: To develop a novel technique for left paralumbar laparoscopic bilateral ovariectomy in standing, sedated mares.Study design: Prospective descriptive clinical study.Animals: Twelve client-owned mares.Methods: Healthy mares with normal ovarian palpation and ultrasonographic appearance were enrolled. Horses were restrained in standing stocks and administered a variable rate infusion of sedation. A left paralumbar bilateral ovariectomy was performed with 1 laparoscopic and 3 instrument portals. Access to the right ovary was facilitated by retracting the descending colon and associated mesentery with a fan retractor. Ovaries were removed with traumatic forceps, and a blunt tip vessel sealing device. A laparoscopic portal within the 17th intercostal space provided good visualization of the right ovary and reduced interference between instrumentation. Complications were recorded during hospitalization. In addition, an owner follow-up questionnaire was used to determine complications after discharge from the hospital.Results: Left paralumbar bilateral ovariectomy was successful in all 12 mares, with a mean surgical time of 76 6 8 minutes. Postoperative complications occurred in 4/12 (33%) mares and included fever, mild colic, incisional swelling, and azotemia. Complications resolved and mares returned to full activity, with complete owner satisfaction.Conclusions: Bilateral ovariectomy can be successfully achieved with minimal morbidity in standing mares with normal ovarian ultrasonographic appearance via left paralumbar laparoscopy.

“…Each ovariectomy approach or technique has associated potential complications or negative impacts such as specialized instrumentation, intraoperative or postoperative risks, or technical difficulty in performing the procedure successfully. Although the use of a morcellator reduces incisional complications, this procedure requires the additional cost to purchase a morcellator and has potential for iatrogenic injury to the uterine horn . Transvaginal natural orifice transluminal endoscopic surgery via colpotomy incision requires customized instrumentation and has decreased visual observation of the caudal abdomen, leading to bilateral ovariectomy not being achievable in all mares .…”

“…Minimally invasive surgery continues to evolve, with recent research focused on further decreasing morbidity and mortality and increasing cosmesis in mares undergoing laparoscopic ovariectomies. Examples include bilateral paralumbar fossa approach with both ovaries extracted through a single unilateral enlarged incision, use of a morcellator in which only 2 portal incisions are created in each paralumbar fossa, and transvaginal natural orifice transluminal endoscopic surgery via colpotomy incision …”

Objective To describe a standing left paralumbar fossa approach combined with mesocolon fenestration for bilateral equine ovariectomy. Study design Prospective experimental clinical study. Animals Four healthy client‐owned mares and 1 client‐owned Molly mule. Methods Mares were restrained in standing stocks and sedated with an α2‐agonist continuous infusion to effect. The abdominal cavity was approached via a left paralumbar fossa approach, and the contralateral right ovary was accessed through an incision in the mesocolon. The location of the window was adjusted to allow triangulation, adequate visualization, and manipulation of the contralateral right ovary. Each ovarian pedicle was ligated with extracorporeal ligatures prior to sharp transection. The ovaries were dropped and left within the abdomen as part of another study. The incision in the mesocolon was closed with laparoscopic staples. Mares were monitored hourly while hospitalized, and a questionnaire was completed by the owners 90 days after surgery. Results Both ovarian pedicles were successfully ligated and transected in all mares through the left paralumbar fossa approach and mesocolon fenestration. The only complications consisted of mild incisional emphysema in 2 of 5 equids, with all resolving spontaneously. All equids returned to intended use at 90 days. Conclusion The left paralumbar fossa approach combined with mesocolon fenestration provided adequate access to both ovaries with minimal morbidity in this small population. Clinical significance A unilateral left paralumbar fossa approach and fenestration of the mesocolon should be considered as an alternative to traditional approaches for bilateral laparoscopic ovariectomies in equids.
