Anal Fissure

Our Approach

Most anal fissures heal by themselves or with nonsurgical treatments, such as creams. But if other conditions, such as muscle spasm or scarring, occur with the fissure, it could interfere with healing. Fissures that do not heal can be fixed with surgery.

At Franciscan Health, we perform anal fissure surgery on an outpatient basis. The large majority of patients who have surgery have no other problems.

What is an anal fissure?

An anal fissure is a tear in the skin of the anus. It can happen when you pass large or hard stools or strain during a bowel movement.

The anus and anal canal are surrounded with muscles that control the passage of stool. These muscles also keep the anus tightly closed when you are not using the bathroom. When the muscles expand, it opens the fissure, causing anal pain and other symptoms.

You can prevent anal fissures by getting enough fiber in your diet. Fiber prevents constipation.

What causes anal fissures?

While severe bouts of diarrhea or inflammation can cause this common condition, it's usually caused by passing large or hard stool. Injury to the anal area during childbirth can also cause anal fissures.

Anal fissure symptoms

If you have an anal fissure, you may experience pain during and immediately following bowel movements. The anus may also itch or bleed.

A simple visual exam of the anus and surrounding tissue usually reveals the fissure.
