An anal fistula is an abnormal tunnel that forms between the anal canal and the skin near the anus, usually after an untreated perianal abscess. Traditional fistula surgery (fistulotomy) can risk damage to the anal sphincter and, in some cases, affect continence. FiLaC (Fistula-tract Laser Closure) is a modern, sphincter-preserving alternative.

How FiLaC works

A fine radial laser fibre is passed into the fistula tract. As it is slowly withdrawn, laser energy uniformly ablates and seals the tract from the inside, allowing it to close without cutting through the surrounding muscle.

Advantages of FiLaC

Preserves the anal sphincter and reduces the risk of incontinence
Minimally invasive, with only small wounds
Day-care procedure and quicker recovery
Can be repeated if a complex fistula recurs

Is FiLaC right for you?

Suitability depends on the type and complexity of the fistula, which is why an in-person assessment is essential. Patients in Karachi can consult laser proctologist Dr. Abdullah Iqbal at Karachi Piles Clinic to discuss whether FiLaC or another laser procedure is appropriate for their case.

Early assessment usually gives the best chance of a smooth, sphincter-preserving repair.
