Perianal Fistulas

Perianal Fistulas are seen commonly in German Shepards and Irish Setters. It is a complicated condition that has anatomic and physiological predispositions. The broad based tail seen in German Shepards keeps the anal area covered so that a fecal film develops in this "skin fold." This fecal film covers the perianal glands with bacteria. Micro abscesses develop in perianal glands eventually coalescing to form larger dissecting fistulas tracts. It is believed that ill defined immunological issues are also involved in the development of this problem. Successful treatment involves surgical debridement and de-gloving of the tracts. Open them up for drainage and ease of treatment. Anal Sacculectomy decreases secretions, perianal debris and bacteria covering the perianal area. Persistent anal cleaning with a mild hand soap (Ivory bar soap) keeps the "skin fold" under the tail clean and dry. Finally the topical application of the immunological suppressant cyclosporine greatly improves post operative cure and resolution of lesions. Persistent and continual therapy is often needed to prevent recurrence.
