The healing time of a perianal abscess wound depends mainly on the size of the wound. If the wound is relatively large and there are more wounds, it may heal in about two months. If the wound is small, it may heal in about forty days to a month and a half. For perianal abscess, which is an infectious disease, the wound usually cannot be sutured, and the wound will be opened directly, and then the wound will be cleaned and changed every day to ensure that the secretions and dirty things that can easily lead to infection can be discharged from the wound and will not lead to infection of the wound. If the wound is stitched up directly, the chance of infection is still quite high. So the doctor will change the medication every day to ensure that the wound grows normally in time, so the wound will grow more slowly.
