Why Does Fistula Come Again After Surgery?
Complete Patient Guide by Dr. Karan R Rawat – Fistula Specialist and Laser Surgeon in Agra
Anal fistula is one of the most frustrating anorectal conditions for patients because even after surgery, some people experience recurrence of the fistula. Many patients ask: “Doctor, why did my fistula come back after surgery?”
According to Dr. Karan R Rawat, a leading gastroenterologist, proctologist, and fistula surgeon in Agra, recurrence usually happens when the root cause of the fistula is not completely treated or the fistula tract is complex.
Understanding the causes of recurrence helps patients choose the right treatment and specialist.
What Is an Anal Fistula?
An anal fistula is an abnormal tunnel that connects the inside of the anal canal to the skin around the anus. It usually develops after an anal abscess infection.
Symptoms include:
-
Persistent pus discharge
-
Pain or swelling near the anus
-
Recurrent boils
-
Skin irritation
-
Occasional fever
Most fistulas require surgical treatment because medicines alone cannot close the abnormal tract.
Top Reasons Why Fistula Comes Back After Surgery
1. Incomplete Removal of the Fistula Tract
The most common cause of recurrence is when the entire fistula tract is not properly identified or removed during surgery.
Fistulas may have:
-
Multiple branches
-
Hidden tracts
-
Internal openings inside the anal canal
If even a small portion of the tract remains, the infection can start again.
2. Complex or High Fistula
Some fistulas pass through deeper anal sphincter muscles. These are called complex fistulas.
Examples include:
-
High trans-sphincteric fistula
-
Supra-sphincteric fistula
-
Horseshoe fistula
These are technically difficult surgeries, and recurrence rates are higher if not managed by an experienced fistula surgeon.
3. Missed Internal Opening
The internal opening of the fistula inside the anal canal is the source of infection.
If this opening is not properly closed or treated, infection continues and the fistula reforms.
This is why accurate identification of the internal opening is critical during surgery.
4. Undiagnosed Underlying Diseases
Certain medical conditions increase the risk of recurrent fistula, including:
-
Crohn’s disease
-
Tuberculosis
-
Diabetes
-
Immunosuppression
If the underlying disease is not treated, the fistula may recur.
5. Inadequate Drainage of Infection
Sometimes a fistula is operated when there is ongoing infection or abscess.
If infection persists, a new fistula tract may develop after surgery.
Proper drainage and infection control are essential before definitive surgery.
6. Improper Surgical Technique
Fistula surgery requires special expertise in proctology. If the surgery is performed without proper mapping of the tract, recurrence becomes more likely.
Modern techniques that reduce recurrence include:
-
Laser fistula surgery
-
VAAFT (Video Assisted Anal Fistula Treatment)
-
LIFT procedure
-
Advanced fistulotomy techniques
7. Delayed Treatment or Long-Standing Disease
Old fistulas that have been present for years often develop multiple branching tracts.
These complex tracts increase the chances of recurrence even after surgery.
Early treatment gives better success rates.
How Recurrence Can Be Prevented
To reduce the risk of fistula recurrence, the following steps are important:
✔ Proper diagnosis with MRI fistulogram
✔ Identification of internal opening
✔ Surgery by an experienced fistula specialist
✔ Complete removal or closure of the tract
✔ Treatment of underlying disease
✔ Good post-operative care and hygiene
