Congenital causes of anorexia can be completely cured, and children with anal atresia who are also anorectal can be treated surgically. Anogenital atresia is caused by anal atresia, which is more commonly a congenital malformation of the digestive tract and is more common in males than females. It is often combined with other malformations. After birth, there is no fecal discharge and symptoms of gastrointestinal obstruction, such as vomiting and bloating, will soon appear. The disease should be treated with surgery as soon as possible after diagnosis, by means of perineal-anal formation surgery. Sacroperineal anomalies can also be used to treat children with high anal atresia, even if the child has a high level of anal atresia, by directly incising the sacrococcygeal region or the abdomen, the blind end of the rectum can be pulled to the perineum, and an artificial anus can be made so that the child can quickly defecate. Postoperative care should be provided to prevent infection of the anus caused by dry stools.
