Laser Perianal Fistula Treatment
A perianal fistula is a tract that forms between the anal canal and the skin due to chronic inflammation. While conventional treatment with fistulotomy may put the sphincter muscle at risk, the modern laser method (FiLaC) markedly reduces this risk.
Overview
Laser fistula treatment is based on placing a thin fiber into the fistula tract and delivering energy to destroy the epithelium and close the tract. Its sphincter-preserving feature is the main advantage of this method.
Who Is It For?
- Fistula patients experiencing recurrent discharge, abscess, and discomfort during bowel movements
- Cases that want to minimize the risk of loss of sphincter continence
- Those with multi-tract, complex fistulas for whom staged treatment is planned
- Suitable fistula cases of cryptoglandular origin other than Crohn's disease
Treatment Process
- 1
Pre-Assessment & Diagnosis
The diagnosis is confirmed and the stage of the disease clarified through a detailed history, physical examination and the necessary imaging and laboratory tests.
- 2
Planning & Preparation
An anaesthesia consultation, bleeding profile and review of any accompanying conditions are carried out; a multidisciplinary council decision is taken when needed.
- 3
Procedure / Operation
The procedure is performed with the technique most suitable for the patient (laparoscopic, robotic or open); tissue integrity and oncological principles are preserved.
- 4
Follow-up & Monitoring
Early mobilization, pain control and wound monitoring are provided; suture removal and a general assessment check-up are planned after discharge.
Recovery & Aftercare
Most patients are discharged the same day; dressings and sitz baths may be necessary.
Hospital Stay
0–1 days
Recovery Time
1–2 weeks
Follow-up
Day 10, week 4, 3 months
Frequently Asked Questions
Is a fistula always treated with surgery?
Surgical treatment is the standard. Medical treatment only helps in controlling an abscess or infection; a procedure is required to close the tract.
Is laser suitable for every fistula?
It is suitable for straight, linear fistulas of cryptoglandular origin. In complex, multi-tract cases and those related to Crohn's disease, a combined approach may be necessary.
Is a single session sufficient?
A single session is sufficient in most cases. Two sessions may be needed for complex fistulas; the success rate is high in appropriate patients.
Does it recur?
With correct treatment, the recurrence rate is low. Crohn's disease, smoking, and hygiene problems increase the risk of recurrence.
