In laser surgery for piles or hemorrhoids, a laser beam is used to burn and shrink the hemorrhoids, which are swollen and inflamed anal tissues. The surgeon focuses a narrow beam of light on the tissues, disrupts the blood flow in the tissues, and allows the tissues to fall off. The procedure is not invasive in nature and causes no bleeding or pain. Laser surgery for piles is usually performed as a daycare procedure where the patient can be discharged within 24 hours. The recovery after the surgery is generally short and effortless.
