IIntroduction: Unilateral laparoscopic ovariectomy is commonly performed in mares including for the removal of pathologic ovaries. Different laparoscopic techniques have been described for ligation and hemostasis of the mesovarium. Objectives: To describe and compare the advantages and disvantages of 2 different techniques used to secure ovarian pedicles: suture ligation and electrocoagulation. Methods: Unilateral ovariectomy was performed in 12 mares between 8 and 20 years of age, of different breed and weight. Standing laparoscopic surgery was performed after sedation with a combination of detomidine HCl and butorphanol tartrate. The portal site, clipped and aseptically prepared with surgical scrub, was locally infiltrated with 30-40ml 2% lidocaine HCl. The enlarged ovary was approached from the ipsilateral paralumbar fossa. Three portals were used for this procedure: one for the laparascopy and 2 for the instruments. The abdominal cavity was inflated using automatic CO2 insufflators. In 6 mares the ovarian pedicles were ligated using a modified Roeder knot with n° 2 polyglycolic acid. In the other 6 horses a bipolar electrosurgical instrument was used to cut the mesovarium and coagulate ovarian vessels. In all cases the ovaries were removed and the incisions were closed in a routine manner. Results: No major operative and postoperative complications occurred. Minor complications included incomplete hemostasis of the ovarian pedicle in 3 mares where surgical ligatures were used (problem solved with double ligatures). Discussion and conclusions: Standing laparoscopic ovariectomy appears to eliminate many of the potential complications associated with traditional surgical methods and avoids the risk of general anesthesia. Suture ligature failure is a potential complication during laparoscopic ovariectomy techniques using ligatures as a means of hemostasis. It’s possible to avoid this complication using electrosurgical instrumentation.
