FiLaC (Fistula-tract Laser Closure)
A radially emitting laser fibre destroys and seals the fistula tract from within - the gold-standard minimally invasive treatment for complex anal fistulas in Hyderabad. Complete sphincter preservation with same-day discharge.
What is FiLaC (Fistula-tract Laser Closure)?
FiLaC (Fistula-tract Laser Closure) is a minimally invasive laser procedure for anal fistulas. A specially designed radially emitting laser fibre is introduced into the fistula tract through the external opening. As it is slowly withdrawn, it emits 360° laser energy that destroys the fistula epithelium and coagulates the tract walls from within - sealing the tract without any sphincter division or large external wound. Dr. Samhitha Reddy offers FiLaC laser fistula treatment in Hyderabad at Lux Hospitals as a leading option for complex and high fistulas where conventional surgery would risk sphincter damage. It is performed under brief anaesthesia as a day-care procedure with a tiny external wound and rapid recovery - making it one of the most sought-after fistula laser surgery options in Hyderabad.
How the Procedure Works
Pre-operative Endoanal Ultrasound
Endoanal ultrasound maps the fistula tract, classification, sphincter involvement, and any secondary branches - ensuring complete laser ablation of the entire tract.
Anaesthesia
Short spinal or general anaesthesia. Procedure in lithotomy position. Entire procedure typically under 20 minutes.
Laser Fibre Introduction
The radially emitting FiLaC laser fibre (360° emission) is introduced through the external opening and advanced to the internal opening under guidance.
Laser Activation & Withdrawal
The laser is activated at 8–12 watts as the fibre is slowly withdrawn at 1 mm/second - coagulating and sealing the tract epithelium from internal to external opening.
Wound Closure
The external opening is lightly sutured or dressed. A very small external wound remains. Patients are discharged the same day with minimal post-operative discomfort.
Outcomes
Who Needs This Treatment?
- →Complete sphincter preservation - no sphincter muscle cut or divided at any point
- →Minimally invasive - small external wound only, no large excisional wounds
- →Day-care procedure - same-day discharge from Lux Hospitals, Hyderabad
- →Very low post-operative pain compared to open sphincter-preserving surgery
- →Can be repeated if needed - does not preclude other techniques
- →Available as part of the leading fistula laser surgery programme in Hyderabad
FiLaC represents the future of complex fistula surgery. The ability to use laser energy to close a fistula tract from within - preserving every fibre of the sphincter - is a game-changer for patients with high fistulas who were previously told their only option was a seton for life.
