An anal fistula is a tunnel that forms inside the anus and connects somewhere in the skin around the anus. An anal fistula usually appears after an infection that does not heal properly. An anal fistula also forms when the glands, inside the anus, get clogged or blocked and causes bacteria buildup inside the anal tissues. In the simplest definition, an anal fistula is an abnormal connection between the anal canal and the perianal skin. An anal fistula can be treated either by open surgery or laser surgery. 

What to expect on the day of laser surgery for anal fistula?

Laser surgery is most commonly performed as a daycare procedure which means the person can return home the very same day of the surgery. However, if the anal fistula had become complex, or the person had to undergo open surgery for hir or her anal fistula, the patient may require to stay in the hospital for a few days until the doctor seems fit.

The surgery may take anywhere between 30-45 minutes, but the person will need to spend extra time in the hospital to prepare for the surgery and after the surgery. 

During laser surgery, the proctologist inserts a radiation-emitting probe into the area where the fistula has developed. The laser radiation emitted from the probe is directed at the fistula to destroy its epithelium and obliterates the rest of the anal channel or anal tract.

What to expect during the recovery process?

How long does it take for a person to recover depends on the complexities and the severity of the anal fistula during the time of laser surgery. At Pristyn Care, each patient of anal fistula is guided by an experienced anorectal surgeon not only during the course of the surgery but also with the best practices for recovery for easy recovery.
