Laser treatment for fistula-in-ano, also known as FiLaCR (fistula laser closure) or LAFT (laser ablation of fistula tract), has gained increasing attention in the last decade.

​

The procedure consists of delivering laser energy at 360° within the lumen of fistulas by means of a radial fiber which is slowly withdrawn from the external orifice. Laser ablation is limited to the lumen of fistulas making the technique ‘sphincter-saving’.

​

Its main indication is the treatment of high fistulas and, in general, of all fistulas where more invasive treatments may impair anal continence.
