What causes an anal fistula? Komaroff, MD Internal Medicine You probably had an abscess pocket of pus that originated in one of the tiny glands that lie just inside the anal canal. The infection made its way beyond the anal canal and into the skin around the outside of the anus. Often, after the abscess breaks opens and drains, the infection can create a thin tunnel-like passageway. This path between the anal canal and the outside anal skin is called anal fistula. The fistula usually surrounds at least part of the anal sphincter muscle.

Anal Fistula Treatment What is Anal fistula? An anal fistula is the result of an infection of an anal gland. This infection arises inside the anal canal and forms a track or a tunnel which opens on to the skin around the anus. The problem usually presents with a small boil near the anal opening. This ruptures and discharges thin fluid or pus. The discharge dries up in a few days only to come back again after a few weeks.
Treatment[ edit ] There are several stages to treating an anal fistula: Definitive treatment of a fistula aims to stop it recurring. Treatment depends on where the fistula lies, and which parts of the internal and external anal sphincters it crosses. Once the fistula has been laid open it will be packed on a daily basis for a short period of time to ensure that the wound heals from the inside out. This option leaves behind a scar, and depending on the position of the fistula in relation to the sphincter muscle, can cause problems with incontinence.
The majority of anorectal conditions are treated surgically only if symptoms persist after a trial of conservative therapy. If patient selection and intraoperative and postoperative care are appropriate, most anal procedures can be performed on an outpatient basis.
