It is usually 90 days from the date of surgery until the mare can return to training. As with all major abdominal surgeries, there is the risk of anesthesia and post-operative complications such as colic. The flank approach is usually performed with the horse standing in stocks, under the influence of a tranquilizer and local anesthetic. Often a four inch incision is made in both flanks to allow the surgeon easier access to each ovary. Removal can be made with an emasculator, such as used in the gelding process or with a chain loop ecraseur.
Recovery is quicker than with abdominal surgery.
However, the vaginal approach requires a higher level of technical experience and may not have widespread availability. Mares must be free from reproductive tract infection and are routinely put on antibiotics before and after surgery. It is especially important when choosing this method to fast the mare for 24-36 hours prior to surgery to ensure minimal intestinal fill. The mare is restrained in stocks, under the influence of a tranquilizer and local anesthetic. The surgeon makes entry through the vulva and a small incision is made in the vagina.
