Understanding Fistula in Ano: A Guide to Symptoms and Recovery

 

While an anal fistula may sound complex, understanding the condition is the first step toward effective treatment. A fistula in ano is essentially an abnormal tunnel that forms between the skin near the anus and the inside of the anal canal. This usually happens as a result of a previous infection or an abscess that didn't heal completely.

​

Because symptoms can flare up and then subside, it is important to recognize the signs so you can seek specialist care.

 

Common Symptoms to Watch For

Fistulas often present with physical discomfort that may come and go. Key symptoms include:

• Pain and Swelling: Constant throbbing or discomfort around the anal area, which often worsens when sitting or moving.

• Persistent Drainage: Noticing pus, blood, or foul-smelling discharge from an opening near the anus.

• Skin Irritation: The skin around the external opening may become red, itchy, or sore due to constant drainage.

• Recurrent Abscesses: If you find that you are frequently developing painful, fluid-filled lumps in the same area, it may be a sign of an underlying fistula tract.

​

Treatment Options

Because fistulas rarely heal on their own, surgical intervention is usually required. Your specialist will recommend an approach based on the location and complexity of the tunnel.

​

• Fistulotomy or lay open

This is the most common procedure for simple fistulas. The surgeon cuts along the entire length of the tunnel, opening it up so it can heal from the inside out as a flat scar.

​

• Seton Placement

If an active infection is present, a surgeon may first place a Seton—a special surgical thread—through the tract. This allows the area to drain continuously, reducing inflammation and clearing the infection before a final corrective procedure is performed.

​

• LIFT Procedure (Ligation of the Intersphincteric Fistula Tract)

This is a specialized technique designed to treat fistulas that pass through the sphincter muscles. It involves accessing the tract between the muscles and tying it off (ligation) to close the tunnel without cutting the muscle itself.

​

• Videos assisted fistula tract surgery (VAFT) or Laser treatment

A laser or small camera is inserted into the fistula tract (tunnel) to burn the tissue within tract to destroy the tract. Performed by specialist surgeons.

 

• Fistula Plug or Medical Glue

In some cases, specialized materials are used to seal the tract. A plug made of collagen or a medical-grade "glue" is inserted into the tunnel to close it and encourage the body’s own tissue to grow over it.

Take the Next Step Every case is unique. If you are experiencing any of these symptoms, the best course of action is to consult a specialist to discuss which approach is safest and most effective for you.
