PERINEAL HERNIA IN A DOG S.R.D. - CASE REPORT

Abstract

Hernia is the displacement of an organ through a defect in the wall of an anatomical cavity. Perineal hernia occurs from the weakening or rupture of the perianal musculature, often caused by trauma. The occurrence is higher in male, non-neutered and elderly dogs, where they most often show signs of tenesmus, constipation, constipation, dyschezia and increased perineal volume. The diagnosis is made through palpation and the treatment can be done by traditional herniorrhaphy or by the technique of transposition of the obturator internus muscle. This work aims to report a case of perineal hernia in an SRD dog, where the herniorrhaphy technique associated with orchiectomy was successfully performed. An SRD dog was treated that had difficulty in defecating and felt pain when he tried. On palpation, an increase in reducible volume in the perianal region, characteristic of hernia, was found. The treatment performed was surgical, performing orchiectomy and subsequent herniorrhaphy, postoperatively, doxycycline, meloxicam and dipyrone were administered, in addition to changing the dressings until the stitches were removed. The musculature at the hernia site was weakened with signs of congestion and fragility, thus suspecting that the cause was trauma, which is one of the causes of hernias. The recurrence rate for the traditional technique is 46%, but it was chosen by the surgeon due to its easy performance and greater mastery of the technique. It is concluded that traditional herniorrhaphy associated with orchiectomy is an efficient technique as no complication or recurrence was observed.
