Rectal fistula: causes, symptoms, and treatment options

A rectal fistula is an abnormal tract that connects the lumen of the rectum to the skin around the anus or to nearby tissues. It most commonly develops as a complication of an inflammatory process and does not go away on its own without treatment.

In simple terms, it is an abnormal passage in the tissues through which pus, blood, or other discharge may drain. Normally, such passages should not be present. They develop when inflammation does not heal completely and becomes chronic.

Why does a rectal fistula develop?

In most cases, the condition develops as a complication of an inflammatory process.

The most common sequence is:

infection → abscess → rupture of the abscess → fistula tract formation

The main causes include:

• previous paraproctitis
• infections of the anal glands
• tissue injuries
• complications following surgery
• chronic diseases

This is why the condition is considered a consequence of another underlying process in the body.

What does a rectal fistula look like and what are its symptoms?

Externally, a fistula may look like a small opening or wound near the anus. Pus or other fluids may periodically drain through this tract.

The most common visible signs include:

• an opening in the skin
• discharge
• redness
• a lump or area of hardened tissue

In addition to these external signs, characteristic symptoms may also occur:

• pain that worsens when sitting or during bowel movements
• itching and discomfort
• purulent or bloody discharge
• recurrent flare-ups
• elevated body temperature

Sometimes, after the pus drains, the condition may temporarily improve. However, this does not mean the problem has disappeared — the tract remains, and the condition may become chronic.

Classification of rectal fistulas

The type of fistula affects the complexity of treatment, so the doctor must determine its specific form.

The main types are listed below:

The more complex the fistula, the more individualized the treatment approach needs to be.

How dangerous is a rectal fistula?

This condition does not resolve on its own and may progress over time.

Possible complications include:

• persistent inflammation
• spread of infection
• formation of additional fistula tracts
• deterioration of overall health

Without treatment, the condition often becomes chronic.

Treatment options for rectal fistulas

The main treatment method is surgery, as it allows the fistula tract itself to be eliminated.

Treatment options include:

• fistula excision
• drainage
• minimally invasive procedures

Medication can only provide temporary relief from symptoms.

Can a rectal fistula be treated at home?

Self-treatment does not eliminate the underlying cause.

Such methods may:

• delay proper treatment
• worsen the condition
• lead to complications

That is why it is important not to postpone seeing a doctor.

Which doctor should you see for a rectal fistula?

If symptoms appear, it is important not to delay consultation. In such cases, you should see a proctologist, who will perform an examination and determine the appropriate treatment approach.

You should consult a specialist if you experience:

• pain or discomfort
• discharge
• elevated body temperature
• recurrent flare-ups

At the ZDRAVO Medical Center, appointments are organized without long waiting times. Patients receive a detailed explanation of their condition and its underlying causes. They are provided not only with a diagnosis but also with a clear understanding of what is happening and how it can be treated.

Timely medical care helps prevent complications and makes treatment considerably easier.

Prevention of rectal fistulas

To reduce the risk of developing this condition, it is important to monitor your health and not ignore the first symptoms.

The main recommendations include:

• timely treatment of inflammatory conditions
• maintaining proper hygiene
• consulting a doctor if discomfort occurs
• avoiding injuries

It is particularly important not to neglect acute conditions, as they are among the most common causes of complications.

Conclusion

A fistula is a complication of an inflammatory process that does not resolve on its own and requires treatment.

The sooner you consult a doctor, the easier the treatment is likely to be and the lower the risk of complications. Ignoring symptoms may lead to a chronic condition and the need for more complex surgery in the future.
