Laser Fistula Surgery (FiLaC)
Laser Fistula Surgery (FiLaC)
Anal fistula is a painful and often recurring condition caused by an abnormal tunnel between the anal canal and the skin around the anus. Traditional surgical methods can involve cutting muscles, leading to pain, long recovery, and risk of incontinence. Laser Fistula Surgery (FiLaC – Fistula-tract Laser Closure) is a modern, minimally invasive solution designed to treat fistula safely while preserving anal sphincter muscles.
When is LIFT Recommended?
The LIFT procedure is best suited for patients with transsphincteric and selected complex anal fistulas, where preservation of sphincter function is essential.
LIFT is commonly advised when:
- The fistula tract passes through the sphincter muscles
- There is a well-defined intersphincteric plane
- MRI shows no uncontrolled abscess or sepsis
- Continence preservation is a priority
- Previous fistula surgery has failed but anatomy remains suitable
Careful MRI-based selection is critical for achieving optimal outcomes.
Procedure
Identification of the Fistula Tract
Using clinical examination and MRI imaging when required, the surgeon identifies the primary fistula tract and internal opening, ensuring accurate localization before surgery.
Small Targeted Incision
A small incision is made in the intersphincteric groove, providing direct access to the fistula tract without cutting the sphincter muscles or damaging surrounding healthy tissue.
Ligation of the Fistula Tract
The fistula tract is carefully isolated, ligated (tied off), and divided within the intersphincteric plane.
This step disconnects the internal opening, preventing ongoing contamination and allowing healing.
Cleaning and Closure
The remaining tract is cleaned and curetted, the incision is closed, and the external opening is left to heal naturally. This promotes controlled drainage and reduces infection risk.
Benefits of Laser Fistula Surgery
FiLaC is a sphincter-preserving technique that offers certain advantages over traditional fistula surgery in appropriately selected patients:
- Minimally invasive – No large cuts or wounds
- Usually associated with less postoperative pain
- Preserves anal sphincter muscles, helping maintain continence
- Lower risk of bleeding and wound complications
- Faster recovery in suitable cases
- Short hospital stay
Because of these benefits, FiLaC has become a preferred choice for patients seeking a safer and more comfortable treatment option.
Our Approach: Precision, Sphincter Preservation & Patient Comfort
FiLaC is a minimally invasive, sphincter-preserving technique that offers certain advantages over traditional fistula surgery in carefully selected patients:
- Usually associated with less postoperative pain and discomfort
- Precision treatment aimed at closing the fistula tract while preserving surrounding tissues
- Promotes healing with minimal tissue trauma
- Helps protect continence by avoiding sphincter division
- Personalized care before, during, and after surgery, based on MRI findings and fistula anatomy
With expertise in modern proctology and minimally invasive techniques, treatment is tailored to each patient to achieve safe, effective, and durable outcomes, while prioritizing continence preservation and quality of life.
Recovery & Post-Operative Care
Recovery after the LIFT procedure is usually smooth and quicker than conventional fistula surgeries.
After Surgery:
- Most patients are discharged within 24 hours
- Mild pain or discomfort may be present for a few days
- No large wounds or extensive dressings required
Recovery Timeline:
- Resume daily activities in 3–5 days
- Complete healing generally occurs within 3–6 weeks
- Follow-up visits ensure proper healing and reduce recurrence risk
Post-Op Care Instructions:
- Maintain good anal hygiene
- Take prescribed medications and antibiotics
- Consume a high-fiber diet to avoid constipation
- Drink adequate fluids
- Avoid straining during bowel movements
Take the Next Step
If you are suffering from pain, discharge, swelling, or recurrent abscess near the anus, early treatment is important. Laser Fistula Surgery (FiLaC) offers a reliable and patient-friendly solution with excellent outcomes.

Frequently Asked Questions
Is Laser Fistula Surgery painful?
Sometimes. FiLaC can be safe for selected complex fistulas, but it is not the best choice for every case. MRI mapping and surgeon assessment decide whether FiLaC or another sphincter-saving procedure is more appropriate.
How long does the procedure take?
The procedure usually takes 30–45 minutes.
Will there be cuts or stitches?
No large cuts or stitches are required. The laser closes the fistula from inside.
Is FiLaC safe for complex fistulas?
Yes. FiLaC is effective for both simple and complex fistulas, including recurrent cases.
What is the recovery time?
Most patients resume normal activities within 2–3 days.
Is there any risk of incontinence?
No. The procedure preserves anal sphincter muscles, greatly reducing the risk of incontinence.
Can fistula recur after laser treatment?
Yes, recurrence is possible after laser treatment, especially in complex fistulas. Careful MRI evaluation and selecting the most appropriate procedure are key to achieving durable results.
