Anal Fistula Causes Diagnosis Treatment ?

An anal fistula is an abnormal skin tunnel which links the anal channel in the colon to the buttocks skin. Fistula mostly occur in response to a pus-filled infection of the anal gland (abscess).

Anal Fistula Causes 

If you have anal abscess, your risk of getting an anal fistula is around 50

There may also be some diseases that may damage your lower digestive system or anal region. which include:

1. Chronic diarrhoea

2. Colitis

3. Crohn’s disease

4. Trauma

5. Sexually transmitted diseases

6. Tuberculosis

7. Diverticulitis (a disease in which small pouches form in the large intestine become inflamed)

8. Radiation treatment for rectal cancer

Symptoms of Anal Fistula

Anal abscess and anal fistula symptoms may be similar and include:

1. Anal pain and swelling

2. Chills and fever

3. Feel tired and sick

4. Skin redness, pain or itching around the anal opening

5. Drainage (pus) of the hole surrounding the anus that have foul-smelling. After the fistula drains, pain might lessen.

6. skin irritation because of pus drainage

7. pain with bowel movements 

Anal Fistula Diagnosis

You may be sent to a specialist for colon and rectal disease if you have any symptoms indicating anal fistula. The specialist will ask questions about your symptoms and medical history. The doctor will check for the fistula in the area of your anal opening during your physical exam. He or she may press the area to examine whether it is painful and if it has pus. Various methods for diagnosis can be employed, for example:

1. Fistula probe. The outside opening of the fistula is guided by a long, thin probe. A specific dye can be administered to detect where the fistula opens in the inside.

2. Anoscope. This is a unique scope for looking at your anal canal.

3. Imaging studies. These might include an ultrasound that uses sound waves to generate a picture of the anal region. Or they may involve an MRI that uses special magnets and computers to create pictures of the region.

Anal Fistula Treatment

Once an anal fistula is present, antibiotics won’t heal it alone. To heal your fistula, you require surgery. The alternatives for surgery include:

1. Fistulotomy. This operation opens up the fistula so that it can heal from the inside. Usually it is an out-patient treatment. You’re going to go home that same day.

2. Filling the Fistula with a Special Glue or Plug. This is a novel treatment that closes the fistula’s internal entrance. The doctor then fills the fistula tunnel with a substance that is absorbed over time.

3. One Stage Reconstructive Surgery. It is done to reconstruct anal sphincters to cure incontinence

4. Seton Placement. This method includes inserting a tightened suture or rubber band (seton) slowly in the fistula. It allows the fistula to cure behind the seton and lowers the risk of incontinence.

In patients with Crohn’s disease, anal fistulas are quite prevalent. Medical treatment is typically performed before surgery for patients with both Crohn’s disease and fistula.


The problems are a recurring fistula after treatment and an inability to regulate bowel movements (fecal incontinence). This is most probable when certain muscles, known as the anal sphincter surrounding the anal hole, are removed.

 Anal Fistula Management

Be sure you take pain medicine as recommended by your surgeon after recovering from anal fistula treatment. Complete all your antibiotics. Don’t take any medication without speaking with your doctor.

Additional key instructions may include:

1. Soak 3 to 4 times a day in a warm bath

2. Wear a pad over the anal region till the treatment is finished 

3. you can start doing your normal activities only if your surgeon allows you. 

4. Eat a high-fiber diet and drink enough of fluids

5. Use a soft stool or bulk laxative as required
