Laparoscopic inguinal herniorrhaphy in two stallions.

Two mature stallions that were used for breeding purposes were admitted for evaluation of inguinal hernias. In 1 horse, the hernia was reduced per rectum by gentle traction applied to the intestine. In the other horse, the hernia was reduced by placing the horse in dorsal recumbency and applying external pressure over the scrotum. Both horses were observed for recurrence of the hernia. Seven days later, an elective laparoscopic technique for inguinal herniorrhaphy was performed on each horse, using polypropylene mesh. Complications did not develop, and both horses have successfully completed 2 full breeding seasons. Laparoscopic inguinal herniorrhaphy allows preservation of the testis on the affected side and precludes many complications associated with open surgical techniques used on inguinal rings.
