Use of polypropylene mesh in addition to internal obturator transposition: a review of 59 cases (2000-2004)

Fifty-nine dogs with a total of 69 perineal hernias that were repaired by internal obturator transposition and polypropylene mesh reinforcement were reviewed. Thirty-six dogs were available for follow-up at a mean of 29.4 months postoperatively. Six dogs had complications within the first 60 days of surgery, such as perineal swelling, persistent tenesmus, and incisional infections. Twenty-two dogs had excellent outcomes; seven dogs needed continued medical treatment after surgery; and seven dogs had poor outcomes. Hernias recurred in five dogs. The incisional infection rate was 5.6%; the recurrence rate was 12.5%; and the overall success rate was 80.5% for the 36 dogs with long-term follow-up.
