Abstract

ObjectiveTo describe successful repair of a diaphragmatic hernia in a standing sedated horse using a minimally invasive thoracoscopic technique.Study DesignClinical report.AnimalsWarmblood mare with a diaphragmatic hernia.ResultsAn 18-year-old Warmblood mare with severe colic was referred for surgical treatment of small intestinal strangulation in a diaphragmatic defect. Twelve days after initial conventional colic surgery, left-sided laparoscopy in the standing sedated mare for diaphragmatic herniorrhaphy failed because the spleen obscured the hernia. One week later, a left-sided thoracoscopy was performed in the standing sedated horse and the hernia repaired by an intrathoracic suture technique. No long-term complications occurred (up to 4 years) and the mare returned to her previous athletic activity, followed by use as a broodmare.ConclusionsTo avoid the high risks associated with general anesthesia, and to reduce surgical trauma and postoperative recovery, central diaphragmatic hernias are amenable to repair using a minimally invasive thoracoscopic technique in the standing sedated horse.
