Anal Fistula: Causes, Symptoms & Advanced Laser Treatment in Agra
If you are experiencing recurrent pus discharge near the anus, swelling, pain while sitting, or repeated abscess formation, you may be suffering from an anal fistula.
Many patients ignore early symptoms, thinking it is piles or a simple infection. However, fistula is a different and more complex condition that almost always requires surgical treatment for permanent cure.
This comprehensive guide explains everything about fistula — causes, types, diagnosis, modern laser treatment options, and when to consult a specialist.
What is an Anal Fistula?
An anal fistula is an abnormal infected tunnel connecting the inside of the anal canal to the skin around the anus.
It usually develops after:
- Perianal abscess
- Untreated anal infection
- Crohn’s disease
- Tuberculosis (more common in India)
- Trauma or previous surgery
👉 Important: Fistula does NOT heal permanently with medicines alone.
How Does a Fistula Form?
- Infection in anal gland
- Pus collection (abscess)
- Abscess bursts or is drained
- A persistent tract forms
If the tract does not close, it becomes a chronic fistula.
Types of Anal Fistula
Understanding the type is important for choosing the right surgery.
1️⃣ Simple (Low) Fistula
- Superficial tract
- Easier to treat
- Good recovery rate
2️⃣ Complex (High) Fistula
- Deep tract
- Multiple openings
- Higher risk of recurrence
- Requires advanced imaging
3️⃣ Recurrent Fistula
- Returns after previous surgery
- Needs expert evaluation
4️⃣ Horseshoe Fistula
- Circular tract around anus
- More complicated
Symptoms of Anal Fistula
- Persistent pus discharge
- Swelling near anus
- Pain while sitting
- Foul smell
- Recurrent abscess
- Fever (during infection)
- Multiple skin openings
Unlike piles, fistula usually causes pus discharge rather than bleeding.
Red Flag Symptoms – When to See a Specialist
- High fever
- Severe swelling
- Spreading redness
- Difficulty passing stool
- Multiple external openings
- Recurrent abscess
Delaying treatment increases complexity.
Diagnosis of Fistula
Clinical Examination
- Visual inspection
- Digital rectal exam
Advanced Investigations
- MRI Fistulogram (Gold standard for complex fistula)
- Endoanal ultrasound
- Colonoscopy (if IBD suspected)
MRI mapping helps reduce recurrence by identifying hidden tracts.
Can Fistula Be Cured Without Surgery?
❌ No.
Medicines may control infection temporarily, but the tract remains present.
Permanent cure requires surgical intervention.
Treatment Options for Anal Fistula
Treatment depends on:
- Type of fistula
- Depth
- Muscle involvement
- Recurrence history
1️⃣ Fistulotomy (For Simple Fistula)
- Tract opened and cleaned
- Effective for low fistula
- Good success rate
2️⃣ Seton Placement
- Used in complex fistula
- Gradual healing
- Protects sphincter muscle
3️⃣ Laser Fistula Treatment (FiLaC Technique)
Modern, minimally invasive option.
Benefits:
- No large cuts
- Sphincter-saving
- Minimal bleeding
- Less pain
- Faster recovery
- Day-care procedure
Laser energy closes the fistula tract from inside.
4️⃣ Video-Assisted Fistula Surgery (VAAFT)
- Endoscopic visualization
- Precise tract identification
- Less recurrence
Laser vs Conventional Surgery – Comparison
| Feature | Laser Surgery | Conventional Surgery |
|---|---|---|
| Incision size | Minimal | Larger |
| Pain | Less | Moderate |
| Recovery | Faster | Slower |
| Hospital stay | Same day | 1–3 days |
| Muscle damage | Minimal | Possible |
Why Recurrence Happens
- Incomplete tract removal
- Hidden secondary tracts
- Complex anatomy
- Crohn’s disease
- Tuberculosis
- Inexperienced surgical approach
MRI-guided planning significantly reduces recurrence.
Frequently Asked Questions (Optimized for PAA & Featured Snippets)
1. What is the main cause of fistula?
Infection of anal glands leading to abscess formation.
2. Can fistula heal on its own?
No, surgery is required for permanent cure.
3. Is laser fistula surgery safe?
Yes, when performed by an experienced proctologist.
4. How long does recovery take?
Usually 5–10 days for minimally invasive procedures.
5. Is fistula a serious condition?
If untreated, it can cause repeated infections.
6. Can fistula turn into cancer?
Rarely, chronic untreated fistula may increase risk.
7. What is the best investigation?
MRI fistulogram.
8. Is fistula surgery painful?
Modern techniques reduce post-operative pain significantly.
Myths vs Facts
| Myth | Fact |
|---|---|
| Fistula is same as piles | Completely different condition |
| Antibiotics cure fistula | Only temporary relief |
| Surgery causes incontinence | Modern techniques preserve muscle |
| Recurrence is common always | Proper mapping reduces recurrence |
