Pseudo healing is a term used in anorectal medicine that basically expresses the fact that there is no real healing in the later stages of anal fistula and perianal abscess surgery. Pseudo healing, as the name suggests, means that the wound has not really healed. The incisions for perianal abscesses and fistulas are usually extraordinarily deep and need to be changed every day to ensure that the wound grows progressively from the bottom upwards and does not form a false cavity, and that the wound is healed in the true sense of the word when it grows out. If the change of medicine is not timely, the incision outside the adhesion, the surface appears to be healed, but the bottom of the formation of potential cavity, is false healing, need to be re-cut, re-medication, so that it is re-grown from the bottom, in order to heal in the true sense of the word.
