Description

Fistula laser closure involves introducing the laser fibre into the fistula from the outside and passing it through to the opening inside the rectum. Then, the laser is activated, causing the tissue around it to shrink as the proteins denature. Therefore, the use of laser treatment as a minimally invasive option may be a preferred alternative for patients seeking sphincter preservation and minimal morbidity, especially in complicated cases of perianal fistula disease.
