HÉRNIA INGUINO-ESCROTAL EM EQUINO DE RAÇA MANGALARGA MARCHADOR- RELATO DE CASO

Abstract

The Mangalarga Marchador national breed is currently the most numerous national equine breed. In horses, in addition to testosterone and morphological alteration of the gubernaculum, modifications in the morphology of the testis are also essential in the migration process, as well as the organs of the abdominal cavity that assist by pushing them into the newly formed scrotal sac. In equines, large intestinal length, long mesentery, and natural movements predispose them to incarceration in natural or acquired openings, including inguinal hernias. Inguino-scrotal hernias are defined by the displacement of the final portion of the jejunum or ileum through the inguinal canal, extending into the scrotal sac. The diagnosis can be confirmed by direct palpation, transrectal palpation and ultrasonography of the testicular pouch. This work aims to report a case of inguino-scrotal hernia in equine of the marcher-wide breed, describing its diagnosis and treatment. A 5-year-old Mangalarga walker presented a testicular (left testicle) enlargement and continuous abdominal discomfort, admitted to the "Equestrian Clinic", and after the diagnosis was immediately referred to the surgery, which consisted of herniorrhaphy associated with Orchiectomy. Postoperative recovery was satisfactory and the animal presented normal physical development for the breed. It was possible in this case to correct the hernia without having to perform enteroanastomosis, since the hernia content was viable and was washed and repositioned to the abdominal cavity.
