An anal fistula is a tunnel that forms in the anus and connects somewhere with the skin around the anus. Anal fistulas usually develop after a lesion that does not heal properly. An anal fistula also forms when the glands in the anus become blocked or blocked, causing bacteria to build up in the anal tissues. In its simplest definition, an anal fistula is an abnormal connection between the anal canal and the anal skin. Anal fistulas can be treated with open surgery or laser. Laser surgery is often performed in a kindergarten, which means that a person can go home the same day after the operation. However, if an anal fistula becomes complicated or a person needs open surgery on an anal fistula, the patient may have to stay in the hospital for a few days until the doctor deems it appropriate. The operation can take between 30 and 45 minutes, but a person will have to spend more time in the hospital preparing for and after the operation. During laser surgery, the proctologist inserts a catheter that emits radiation into the area where the fistula formed. The laser radiation emitted by the detector is directed to the fistula to destroy its epithelium and remove the rest of the anal canal or street.
