Most of the post-operative incisions of hemorrhoid surgery are open, so when they are open they need to be cleaned and disinfected and actively changed. The purpose of the initial change of medication is to fill the oil gauze, first, to prevent the trauma from being contaminated by feces. Second, the oil gauze strip can stimulate the growth of the wound granulation, but at a later stage when the growth of the granulation is about the same, it is not necessary to change the medication plug gauze strip, if the granulation grows higher than the skin, but will affect the healing of the incision skin. In the later stages, you just need to pay attention to the cleaning and disinfection of the anal area after the bowel movement, and then put a thin layer of gauze on the incision. In addition, hemorrhoid patients who find that the granulation is higher than the skin need to go to the hospital promptly, the granulation may need to be trimmed to promote the healing of the skin.
