What is a low anal fistula?

False healing after anal fistula surgery is that the skin of the outer mouth grows fast and the inner mouth grows slowly. When it is deeper, the base has not yet grown, and the upper part grows first. In the base, a fistula will form. This is false healing. If the patient has other diseases, such as diabetes, anemia, etc., he should actively control complications, select antibiotics, re-incision the closed skin incision, place drainage strips, ensure adequate drainage, and completely remove the focus. After anal fistula surgery, dressing change should be carried out every three or two days to keep the drainage of the wound unobstructed, accelerate wound healing and prevent false healing.
