PERIANAL HERNIA IN A DOG - CASE REPORT (Atena Editora)

Abstract

Perineal hernias are characterized by weakening and tearing of one or more muscles and fascia that form the pelvic diaphragm. Because of this, the caudal abdominal cavity and/or pelvic organs are found in the perineal region. The pathology affects more male, elderly and non-neutered dogs, which may show signs of impairment of the urinary and/or digestive tract, such as difficulty urinating and/or defecating. The definitive diagnosis can be made through rectal palpation to determine the structures that form the perineal swelling and by carrying out radiographic and ultrasound examinations. Among the most effective pelvic diaphragm reconstruction techniques are single or combined muscle transpositions, such as those of the obturator internus muscle or superficial gluteal muscle. In cases of recurrence, complementary methods can be used, such as colopexy and cystopexy by fixation of the vas deferens, or transposition of the semitendinosus muscle. This disease is a condition with high rates of recurrence and postoperative complications. Therefore, the choice of surgical method to be used must be made taking into consideration, the clinical condition of the animal. A clinical case report of a seven-year-old male, Lhasa Apso dog, weighing six kilos and diagnosed with bilateral perianal hernia, where the surgical procedure performed was bilateral perianal herniorrhaphy and orchiectomy, will be reported. This work aimed to make a case report of perineal hernia in dogs along with a literature review, addressing the anatomy of the perineal region, epidemiology, clinical signs, diagnosis, treatment and postoperative complications.
