Laser Treatment for Anal Fistula by Laser Diode

By | August 14, 2018

An anal fistula is a small channel that is found between the end of the bowel and the skin near the anus. It occurs as a result of a previous or current anal abscess. Fistula has a tract of two openings – Internal opening into the anal canal and External opening by the skin of the buttocks. If the anal fistula is not cured on time, it may cause a lot of complications Treatment of fistula on time is highly recommended.

FiLAC or Fistula laser closure is a novel anal sphincter-saving procedure to treat anal fistula. Primary closure of the track is get using laser energy emitted by a radial fiber connected to a diode laser. The energy causes contraction of the tissue around the radial fiber to closes the track. The laser FiLaC technique for an anal fistula is relatively simple, safe, minimally invasive and sphincter-saving procedure with a high success rate.

Steps involved in the FiLAC:

Hydrogen peroxide or methylene blue is injected from the exterior opening to identify the inner opening of fistula.
Then Fistula tract is debrided with the curate.
Through guide wire, a plastic hollow 14F catheter is inserted into the tract.
Radial-emitting disposable laser fiber is inserted into the catheter with its tip emerging at the interior opening.
Diode Laser is used, fiber delivers laser energy homogenously and the tract is closed. Slowly it is withdrawn


It is a relatively simple procedure.
It doesn’t affect continence function.
Healing and recovery time is less.
Chances of success in this procedure are very high.
