What is a high anal fistula?

A high anal fistula is simply an abnormal passageway that occurs near the anus, connecting the anus with an opening outside the body. The "high" in a high anal fistula refers to the fact that the fistula is located deep inside the anus, usually passing through the upper part of the anal sphincter. This term may be unfamiliar to many people, but if you have ever experienced abnormal pain or swelling around the anus, you need to pay special attention.

Anal fistulas are usually caused by a perianal abscess that fails to heal completely, leaving a channel. Imagine that the tissue around the anus is like a sponge, and the abscess is like a hole dug in the sponge. If this hole does not heal, a fistula may form. High anal fistulas are longer and deeper, and may cause more complex symptoms, such as persistent pus discharge, pain, and even affect daily life and work.

So, how do you tell if you have a high anal fistula? This is not something that can be determined by simple observation. Usually a professional doctor is required to conduct an examination, and an anoscope or imaging examination may be used to confirm the specific location and direction of the fistula. For patients, it is important to pay attention to changes in their own body, especially abnormal sensations around the anus.

Treatment for high anal fistulas usually requires surgery, which may sound a little worrying, but modern medical technology has made this problem very effective. The goal of surgery is to remove the fistula and promote healing. The recovery period may take some time, but most patients will experience significant improvement after surgery. To promote healing, your doctor may recommend increasing your fiber intake, maintaining good bowel health, and avoiding constipation.

Although high anal fistula sounds complicated, it can be effectively controlled as long as you seek medical attention in time and receive appropriate treatment. Maintaining good living habits and paying attention to changes in the body are important measures to prevent and deal with anal fistula. Remember, a healthy body requires us to listen and care carefully.
