Second, damage to the anal area below the surface skin, the length of more than 1cm, in the case of local drug changes without skin infection, in 7-9 days can be completely healed. Third, damage to the anal sphincter, because it is difficult for the muscle to recover on its own, after the surface skin has recovered in 7-9 days, the function of the anal sphincter has not yet recovered, such as the emergence of symptoms such as fecal incontinence requires surgical treatment, and it takes two weeks to recover after surgery. Fourth, the patient himself has underlying diseases that affect wound healing, such as diabetes, which requires healing after blood sugar control, and the recovery time will be relatively prolonged by about a week. Fifth, wound infection, may delay healing, there is also the possibility of non-healing, infection control in 10 days after the recovery.
