When the gauze can be removed after hemorrhoid surgery depends on the recovery of the wound. Normally, if the painful symptoms of the wound gradually disappear as well as there is no more bleeding, the gauze can be removed about 7 days after hemorrhoid surgery. The main purpose of wrapping the wound with gauze after hemorrhoid surgery is to prevent the wound from being infected by external bacteria and also to provide some hemostasis to the wound. The tissues and skin around the anus grow and recover slowly, so in order to promote healing, you need to insist on daily dressing changes and timely cleaning of the area around the anus to prevent fecal and bacterial growth. The gauze should be removed after the wound is completely healed, and should be replaced promptly if the gauze is contaminated during the use of the gauze.
