Laser anal surgery

The word fistula is a word that is somewhat incomprehensible in our societies, but it is possible for simplification to liken it to a tunnel, because an anal fistula is an abnormal tunnel that connects between the anus and the surface of the skin.

What are the causes of anal fistula:

  • Bacterial infection of the glands in the anal canal
  • Formation of an abscess containing pus in the anal area
  • Tuberculosis
  • cancer
  • Crohn’s disease
  • Sexually transmitted diseases like syphilis
  • surgical injury

What are the symptoms of an anal fistula:

  • Repeated complaint of anal abscess that reoccurs despite its treatment
  • Pain in the anal area that increases with defecation, and usually the pain is similar to purulence, and this is due to the presence of internal pus
  • Swelling in the anal area
  • Drops of blood with stool
  • Bloody or purulent secretions come out of an abnormal opening in the anal area, and the patient may feel comfortable after emptying this pus

Laser treatment of anal fistula

If you suffer from fistula or know someone who has suffered from it, then in this article we will show you a new way to treat fistula other than traditional surgery. With us, you will learn about the laser fistula process, its advantages and the techniques used with it.

anal fistula

Anal fistula is an opening or erosion in the inner tissue of the anal muscle and the surface of the skin, and fistula in general is an opening or tunnel that connects two organs of the body, and there are other types of fistula such as:

  • Vaginal fistula.
  •  Pilonidal sinus.

Laser fistula surgery

FiLac is a modern technique for treating anal fistula with laser, as a laser catheter is inserted through the opening of the fistula to reach the anus, so that the tissues responsible for creating the fistula can be removed by cauterizing through laser light, and the surgeon may sew some stitches inside the anal canal after that during Gradual exit of the laser catheter.

The laser fistula operation appeared in 2011, and it was found that it removes the fistula and destroys its remnants, and the internal opening of the fistula is closed, unlike what happens in surgical operations, as there are remnants of the fistula.

Laser fistula surgery techniques

Usually, the surgeon uses some other techniques in addition to using the laser to close the internal fistula opening, and these procedures include:


It is a surgical stitch that causes a kind of fibrosis to close the opening of the fistula. It is performed to preserve the function of the anal valve muscle, which is to control stool and prevent fecal incontinence.

endoscope (VAAFT)

In this technique, a telescope with a video camera is used to remove the fistula tissue, and this procedure preserves the anal valve muscle.


During this procedure, a stopper is placed inside the fistula made of medical material after cleaning the fistula, in addition to closing the internal fistula opening.

 Fistula connection between the two muscles of the anal valve (LIFT)

In this technique, the surgeon connects and closes the fistula channel between the internal and external anal muscles.

Advantages of laser fistula surgery

Fistula patients are looking for an effective, painless treatment to eliminate fistula and not suffer from fecal incontinence at the same time, as the traditional surgery procedure may negatively affect the anal muscle and the tissues surrounding the fistula, leading to loss of the ability to control the anal muscle and the ability to prevent stool. and gases.

As for the laser fistula surgery, the fistula is removed and its opening is closed, without harming the surrounding tissues and the anal valve muscle is preserved, which makes the patient retain his ability to control the anal muscle, and he does not suffer from fecal incontinence, and we will explain the most important advantages of the laser fistula surgery :

  •  The process does not take long, as it is performed in approximately 15 minutes.

  • This procedure is less painful than traditional fistula surgeries.

  • Preserve the anal valve muscle, avoid fecal incontinence.

  •  This procedure ensures absolute control and precision during surgery, and minimizes the possibility of ablation or separation and all risks associated with infection or other complications.

  •   The flexibility of the fiber laser helps access the fistula even if it is in an anatomically difficult location.

  • No matter the length of the fistula, the laser can remove it, regardless of its length.

  •  Laser helps speed recovery.

  •  Lasers can be combined with other techniques to close the fistula opening.

Important tips after anal fistula surgery:

It is necessary to maintain hygiene procedures, and to eat foods rich in fiber: such as vegetables and fruits, because this helps to facilitate the passage of stool without causing complications in the anal canal, laxatives: they are prescribed by the doctor to avoid constipation during the recovery period.
