Internal Obturator Transposition Herniorraphy of Three Perineal Hernia Cases in Dogs

Abstract

Case Description.: In this present study three cases of perineal hernia in dogs have been presented and new concepts in perineal herniorrhaphy have been introduced. A 5-year-old intact male Spitz dog, a 6-year-old intact male dachshund dog and a 4.5-year-old sexually intact male Welsh corgi dog were referred with swelling around the anus and dyschesia. Clinical Findings: The owner complained about a sudden enlargement of the right perineal region. Physical examination revealed soft bulged area surround and in the right side of anus. Plain radiograph showed normal position of urinary bladder and prostate. Treatment and outcome: All the dogs were treated surgically by the internal obturator muscle flap technique which were transposed dorso-medially into the defect and sutured into defect borders. No complication was observed after surgery in any of the dogs. The dogs were monitored weekly for one month. The final evaluation revealed that all dogs were clinically normal and the owners were fully satisfied with the outcome. Clinical Relevance: This study proved that the internal obturator transposition technique was superior technique for perineal hernia cases among all suggested techniques.
