Surgery for Fistula in Ano

Anal fistula (fistula-in-ano) is an abnormal connection between the epithelialised surface of the anal canal and the perianal skin. Anal fistulae originate from the anal glands, which are located between the two layers of the anal sphincters that drain into the anal canal. If the outlet of these glands becomes blocked, an abscess can form which may form a tract as described above. Abscesses can recur if the fistula seals either internally or externally. Anal fistulas can be very painful and can be irritating because of the continuous drainage. Recurrent abscesses may lead to significant short term morbidity from pain and led to systemic infection. Surgery is essential in the decompression of acute abscesses. Repair of the fistula itself is considered an elective procedure.
