OVERVIEW
Advanced Laser Technology for Safer, More Comfortable Fistula Treatment
An anal fistula is a small, painful tunnel that forms between the inside of the anal canal and the skin around the anus, most often as a result of a previous infection or abscess. It can cause persistent discharge, discomfort, and recurrent swelling if left untreated. Laser Fistula Treatment uses focused laser energy delivered through a fine probe to gently close the fistula tract from within, sealing it while minimizing injury to the surrounding tissue — offering a sphincter-preserving alternative to conventional fistula surgery, with less pain and a faster recovery.
CANDIDACY
Who May Benefit from Laser Fistula Treatment?
Persistent pain around the anus, swelling or a lump near the opening, pus or blood discharge, or recurrent skin irritation may indicate an anal fistula. When these symptoms continue or infections keep recurring, timely surgical treatment is needed to prevent complications and preserve normal anal function.

PROCEDURE
How Is Laser Fistula Treatment Performed?
1
Anesthesia
The procedure is usually performed under general or spinal anesthesia to ensure patient comfort.
2
Examination of the Fistula
The surgeon carefully identifies both the internal and external openings of the fistula and evaluates the entire tract.
3
Cleaning the Fistula Tract
Any infected tissue or debris inside the fistula tract is gently removed to prepare it for laser treatment.
4
Laser Closure
A thin radial laser fiber is inserted into the fistula tract, delivering controlled energy that seals the tract from within while preserving surrounding sphincter muscle.
5
Final Assessment
The treated area is examined to ensure the procedure has been completed successfully before the patient is prepared for recovery.
GOOD TO KNOW
As with any procedure, laser fistula treatment carries some general risks. These are uncommon and are discussed in detail during your consultation:
•Temporary pain or discomfort
•Mild bleeding or discharge
•Delayed healing
•Recurrence of the fistula
•Need for additional treatment in complex cases
RECOVERY
Recovery After Laser Fistula Treatment
First 24 Hours
Mild discomfort, light drainage, and temporary swelling may occur.
First Week
Walking is encouraged, and many patients resume light daily activities.

Wound healing continues, and symptoms gradually improve.
4–6 Weeks
Most patients experience significant recovery, although complete healing varies depending on the fistula.
FAQ
Common Questions
Most patients experience only mild discomfort after the procedure because it is performed under anesthesia and the treatment itself is minimally invasive.
The procedure usually takes around 20 to 45 minutes, depending on the complexity of the fistula.
In many cases patients can return home on the same day, though this can depend on individual circumstances.
