Anal Fistula Fistula-in-ano
Fistulectomy is a surgical procedure where a fistulous tract is excised (cut out) completely. This procedure is done to remove a perianal fistula that can form after someone develops a perianal abscess. The fistula may form 4-6 weeks or even a year after the initial abscess, and about 50 percent of abscesses will develop a fistula.
A fistulectomy is performed on an outpatient basis using a local anaesthetic or a spinal. The surgery takes approximately 45-60 minutes. There are 3 important parts of a fistula to identify prior to or at the beginning of the surgery.
• The external opening, which is usually obvious around the anal opening on the outside.
• The tract, which is the connection between the external and the internal openings.
• The internal opening, which is not always evident until during the surgery. Sometimes a blue dye is injected into the external opening to allow identification of the internal opening at the time of surgery.
The fistulectomy consists of removing or opening the 3 components, which is done by dividing the least amount of sphincter muscle as possible. The location of the internal opening will usually dictate how much of the sphincter muscle will be cut or divided. The further up inside the anal canal or rectum the internal opening is located, the more muscle will have to be incised or cut through, leading to more of a risk of leakage or drainage after the wound has healed.
Once the fistula has been removed, the groove or wound is left open to heal. Some fistulas can be very complicated and may require more than 1 surgery.
The healing process usually takes 4-6 weeks. Pain medication and antibiotics will be given at discharge. There will be several post-op office visits required. Our La Peer doctors use minimally invasive techniques that promote quicker healing and less pain. We welcome you to call our surgical centre to learn what options are available to you.
