What is a Fistula (Bhagandar)?
When it comes to anorectal health, social stigma often leads to widespread misunderstandings. Most patients suffering from anal pain, swelling, or discharge instinctively assume they have Piles (Bawasir). However, self-diagnosing or relying blindly on over-the-counter ointments can lead to severe health consequences. Quite often, what people mistake for structural piles is actually a deeply rooted, infectious tracking condition known as a Fistula-in-Ano or Bhagandar.
At Kaizen Fistula Care in Pune, we believe that an informed patient makes the safest medical choices. This comprehensive guide features clinical insights from Dr. Samrat Jankar, a leading advanced fistula specialist in Pune, India. By understanding the true anatomy of a fistula, you can stop relying on temporary fixes and seek a permanent cure.
What Exactly is a Fistula-in-Ano? (The Ghost Tunnel)
A fistula does not develop overnight; it is almost always the consequence of a neglected or improperly drained anal abscess (a severe collection of pus). Tiny fluid-secreting glands line the inside of the anal canal. When one of these glands gets blocked, bacteria multiply rapidly, creating an acute abscess.
When this abscess bursts open on its own or is cut open superficially without addressing the root cause, it leaves behind an active path. This permanent underground passage is your fistula, physically connecting an internal opening inside your anus to an external opening on your skin.
The 5 Steps of the Deceptive Fistula Cycle
This condition is often referred to as a “Ghost Tunnel” because of its highly deceptive healing cycle:
- The Onset: Near the back passage, a small hole or painful boil forms. Sometimes it leaks fluid or pus.
- The Burst: The small painful boil bursts, the fluid drains out, and the acute pain instantly goes away.
- The False Recovery: The skin closes and superficially heals, giving the patient intense hope that the problem is completely gone.
- The Re-infection: Because the inside of the tunnel is connected to the inside of the back passage—where germs naturally live—it remains slightly infected.
- The Repeat: The tunnel keeps oozing, accumulates pus again, and a small bump starts building up. This cycle of healing, bursting, and draining can repeat at least 5 or 6 times over several years, leading patients to think it is just piles acting up.
How a fistula in ano is formed?
A fistula-in-ano forms when an abnormal tunnel or connection develops between the anal canal and the skin near the anus. This condition typically arises as a complication of an infected anal gland or an untreated anal abscess. Here’s how it develops step by step:
- Infection in the Anal Glands: The anal canal contains small glands that secrete mucus to help bowel movements. Sometimes, these glands can become blocked, leading to an infection.
- Formation of an Abscess: The infection often results in the formation of a pus-filled cavity known as an abscess. This is the first stage of fistula development. The abscess causes pain, swelling, and redness around the anus.
- Bursting or Inadequate Healing of the Abscess: If left untreated, the abscess may burst or drain spontaneously through the skin, creating a pathway for pus to escape. However, in some cases, even after surgical drainage of the abscess, the tissue does not heal properly.
- Chronic Inflammation and Fistula Formation: Persistent inflammation or incomplete healing can result in the formation of a permanent abnormal tract between the infected anal gland and the skin. This is known as a fistula.
- Recurring Infections: The fistula often allows fecal matter and bacteria to pass through the tunnel, causing recurrent infections and drainage from the external opening of the fistula.
- Chronic Condition: Once formed, the fistula often becomes a chronic issue, as the tract does not heal naturally and requires medical or surgical intervention.
If you notice any symptoms such as persistent discharge, pain, or swelling near the anus, consult with a fistula specialist in Pune promptly.
How to Spot a Fistula: 5 Classic Signs
If you are experiencing chronic discomfort around your back passage, it is time to move past guesswork. Based on extensive clinical insights from Dr. Samrat Jankar at Kaizen Fistula Care, look out for these 5 definitive, classic signs of a fistula-in-ano:
- The Stain: Noticing a small wet spot or recurring stain on your underwear caused by leaking fluid or pus.
- The String: If you press gently under the skin near the back passage, you may feel a firm, cord-like hardness. That rigid line is the physical tunnel.
- The Hole: A visible small opening or raw puncture on the skin outside. In advanced or neglected cases, there can sometimes be more than one hole.
- The Itch: Constant mild itching and skin irritation around the back passage caused by the continuous discharge.
- The Cycle: The highly predictable abscess-burst-heal-repeat pattern where the wound relaxes, closes, and builds up again every few weeks or months.
