fistula-in-ano
A fistula-in-ano is an epithelial-lined tract connecting the anal canal to the perianal skin. Anal fistulas can have many causes but are most commonly the result of a previous or current anorectal abscess due to frequent infection of perianal glands. This occurs in up to 40% of patients with abscesses. Patients with fistulas commonly have a history of a previously drained anal abscess
Fistulas are classified by their relationship to parts of the anal sphincter complex (the muscles that allow us to control our stool). They are classified as intersphincteric, transsphincteric, suprasphincteric and extrasphincteric. The intersphincteric is the most common and the extrasphincteric is the least common. These classifications are important in helping the surgeon make treatment decisions
Anorectal pain, swelling, perianal cellulitis (redness of the skin), drainage from the perianal skin, irritation of the perianal skin and fever are the most common symptoms of fistula. Occasionally, rectal bleeding or urinary symptoms, such as trouble initiating a urinary stream or painful urination, may be present.
