Anal Atresia Treatment
Anal atresia requires immediate surgery in order to make a clear passage for stool. Imperforate anus surgery depends on the form and severity of the lesion. A low lesion is normally repaired very early in life by a procedure called the perineal anoplasty. In a high imperforate anus a colostomy is performed almost immediately after diagnosis. A colostomy is a temporary opening in the large intestine where waste can be excreted. The colostomy remains for several months, letting the baby grow, until a new anus can be surgically made.

Anal Atresia Prognosis
Prognosis is usually good once the anal atresia is treated. In severe cases with high lesion, however, a child may never gain complete control of his or her bowel movements. Some children may also suffer from constipation.
Anal Atresia Complications
- Bowel incontinence
- Intestinal blockage
Anal Atresia Cause
The exact cause of this congenital defect is not known. Research has linked other congenital malformations to the use of antidepressants during pregnancy. Baum Hedlund is investigating a possible link between the use of antidepressants in pregnancy and the risk of imperforate anus at birth.
