Anal Fistula

Overview

An anal fistula is a chronic infected tunnel that runs from the anal canal to the skin near the anus. The anus is the external opening through which feces are expelled from the body. Just inside the anus are a number of small glands that make mucus. Occasionally, these glands get clogged and can become infected, leading to an abscess. About half of these abscesses may develop into a fistula.

Symptom

● Frequent anal abscesses
● Pain and swelling around the anus
● Bloody or foul-smelling drainage (pus) from an opening around the anus. The pain may decrease after the fistula drains.
● Irritation of the skin around the anus from drainage
● Pain with bowel movements
● Bleeding
● Fever, chills, and a general feeling of fatigue
You should see your doctor if you notice any of these symptoms.

Treatment

An operation is almost always necessary to treat an anal fistula. The operation is performed by a colon and rectal surgeon. The aim of the operation is to strike a balance between removing the fistula and protecting the anal sphincter muscles, which could cause incontinence if damaged.

The Fistura® procedure uses radiofrequency thermocoagulation to treat anal fistulas – using very high frequency (4MHz) electromagnetic waves, similar to the principle of a microwave.

This new treatment is performed on an outpatient or day-case basis.
The procedure takes only a few minutes, with minimal discomfort for the patient, allowing an immediate return to daily activities.
