Anal Gland Fistulas

An anal gland fistula is an abnormal tunnel that forms between the anal canal and the skin near the anus. It’s usually caused by an infection of the anal glands, which leads to the formation of an abscess (a collection of pus). When the abscess bursts or is drained but the underlying infection isn’t completely cured, a fistula can develop.

This condition is painful and can cause discomfort, drainage of pus, and sometimes infection. It’s a common problem that can affect both men and women but tends to be more frequent in men.

Anatomy of Anal Glands and Anal Gland Fistula

Anal Glands Structure

The anal glands are small glands located just inside the anus, at the junction between the rectum and the anal canal. Their main function is to produce a lubricating fluid that helps in stool passage. These glands can become blocked or infected, leading to the development of a fistula.

Blood Supply

The anal canal and surrounding structures are supplied by the inferior rectal artery, which is a branch of the internal pudendal artery. Good blood flow is essential for healing any infection or surgery related to anal gland fistulas.

Nerve Supply

The anal area is richly supplied by nerves, particularly the inferior rectal nerves, which are branches of the pudendal nerve. This nerve supply is responsible for sensations of pain, itching, and other sensations in the anal region, making conditions like anal gland fistulas very uncomfortable.

Types of Anal Gland Fistulas

Anal gland fistulas are categorized based on their location and complexity:

• Intersphincteric Fistula: The most common type, running between the internal and external anal sphincters.
• Transsphincteric Fistula: Extends through both the internal and external sphincters.
• Suprasphincteric Fistula: Extends above the external sphincter and then back down to the skin surface.
• Extrasphincteric Fistula: Rare, begins higher up in the rectum and extends through the levator ani muscles to the skin.
• Subcutaneous Fistula: A shallow fistula located just under the skin near the anus.

Frequently Asked Questions (FAQs) about Anal Gland Fistula

1. What is an anal fistula?
   An anal fistula is an abnormal connection between the anal canal and the skin near the anus, usually caused by infection.
2. How is an anal fistula different from an abscess?
   An abscess is a pocket of infection, while a fistula is a tunnel that often develops after the abscess drains.
3. Can a fistula heal on its own?
   It’s unlikely; most fistulas require medical or surgical treatment to heal completely.
4. What are the common symptoms of an anal fistula?
   Pain, swelling, discharge of pus, and sometimes fever.
5. How is an anal fistula diagnosed?
   Through physical examination, imaging tests like MRI, or endoscopic procedures.
6. Can anal fistulas recur?
   Yes, fistulas can recur even after treatment, particularly in individuals with underlying conditions like Crohn’s disease.
7. Is surgery always necessary for an anal fistula?
   Not always, but many cases require surgery to heal properly.
8. What are the risks of surgery?
   Risks include infection, recurrence, and in rare cases, damage to the anal sphincter leading to incontinence.
9. What happens if an anal fistula is left untreated?
   It can lead to chronic infection, worsening pain, and complications like sepsis.
10. Are there any non-surgical treatments for fistulas?
    In mild cases, antibiotics, fibrin glue, or setons might be used, but surgery is often the most effective option.
11. How can I prevent an anal fistula?
    Maintaining good hygiene, eating a fiber-rich diet, and treating any infections early can help prevent fistulas.
12. Is an anal fistula a sign of cancer?
    Most anal fistulas are not related to cancer, but some cases may arise from cancers, so proper diagnosis is essential.
13. Can an anal fistula cause complications?
    Yes, complications like infection, abscess formation, and in rare cases, incontinence can occur.
14. How long does recovery from fistula surgery take?
    Recovery varies, but most people heal within 6-12 weeks after surgery.
15. Can a fistula come back after treatment?
    Yes, recurrence is possible, especially if the underlying cause (like Crohn’s disease) isn’t treated.
