False healing of the wound after anal abscess surgery can not be judged by yourself. False healing of the wound after anal abscess surgery can be detected by color ultrasound under the doctor’s examination, in the ultrasound probe to find the abscess, you can judge whether it is completely healed or there is a residual pus cavity, which can not be judged by yourself. False healing of the wound after anal abscess surgery is mainly due to the strong healing ability of the external skin opening, the internal pus cavity is slow to recover, the residual cavity or pus cavity is left behind to heal slowly, and the patient’s tissue hyperplasia of the external opening is more obvious, which results in the false healing of perianal abscess. If the perianal abscess is completely healed, the pain and swelling will disappear obviously; if it is pseudo healing, only the epidermal external opening is healed, but there is bulging pus or abscess around it, there will be obvious pressure and pain or throbbing pain and swelling, and in serious cases, there will be fever and other symptoms. Patients need to pay attention to observe their own situation, if discomfort occurs, need to go to the hospital in time, with the help of doctors, targeted treatment.
