Laparoscopy is a form of minimally invasive surgery in which an endoscope is inserted through a small incision into the abdominal cavity in order to examine the abdominal organs or to perform surgery within the abdomen. Diagnostic laparoscopy is used to evaluate horses experiencing recurrent episodes of colic or chronic abdominal pain. Laparoscopic surgical procedures performed in the horse include removal of ovaries (ovariectomy) or retained (cryptorchid) testicles as well as some assisted reproductive surgical techniques.
In the laparoscopic image to the right, the ovary has been dissected freely from its pedicle, using laparoscopic surgical technique. The device seen entering the abdomen from the upper right corner is a specialized vessel sealing instrument (Ligasure Atlas) which prevents unwanted hemorrhage during the procedure by ensuring blood vessels are completely coagulated prior to cutting the tissue.
