The sequelae of infant anal fistula surgery include postoperative recurrence, anal moisture and itching, anal incontinence, anal deformity and so on. 1. Postoperative recurrence: if the examination is not clear, positioning errors lead to incomplete surgical treatment, postoperative anal fistula recurrence is more likely. 2. Anal moisture and itching: patients with large surgical scope, if the postoperative anal closure is not tight will lead to fecal water leakage in the intestine, resulting in frequent anal moisture and itching. 3. Anal incontinence: If the anorectal ring is cut off during surgery, it will lead to anal incontinence. 4. Anal deformity: If the direction of the surgical skin incision is wrong or the excision wound is too large or improper care may lead to poor wound healing, resulting in anal deformity. After the surgery of infant anal fistula, if there is a complication, you need to consult a doctor in time, active treatment, to avoid aggravation of the condition.
