An anal fistula is an abnormal communication between two epithelial surfaces - the perianal skin and the anal or rectal lumen (1).

  • this abnormal tract is lined with granulation tissue
  • it may harbour chronic infection resulting in continuous or intermittent discharge through the external opening on to the skin
  • soiling of underwear and skin irritation may be seen in severe cases due to faecal material passing through the tract (1)

In England, incidence of anal fistula is 18.4 per100,000/year. More common in men (twicw as likely to be affected) with peak around 40 years of age (1).

Fistulae may be complex, with several openings onto the perianal skin (2).
