Atresia ani is a disease that generally occurs in infants. This condition is in the form of the large intestine or part of the baby’s large intestine which is not yet fully formed. This causes the large intestine to become blocked and very narrow. Some babies do not have an anal opening. The large intestine is the least common site of atresia in the digestive tract. Immediate and appropriate treatment is needed because this disease is a serious disease. The majority of babies need surgery to correct this situation. The cause of atresia ani is still unknown, preventing further action. Atresia ani is quite common (1/5000 newborns) and is more prone to male babies. This condition can affect child development and risk factors can be reduced with proper treatment.



Some of the signs and symptoms of atresia ani:

  • Gag
  • Does not have an anal opening
  • Having the anal canal in an inappropriate place, such as too close to the vagina
  • There is a membrane covering the anal canal
  • The intestine is not connected to the anus
  • Abnormal connection between the intestine and urinary system, the stool can pass through the urinary system, such as the urethra, vagina, scrotum, or base of the penis
  • Do not pass stool for the first 24 – 48 hours after birth
  • Have a swollen stomach
  • Having an abnormal connection, or fistula, between the rectum and the reproductive system or urinary tract

Babies with atresia ani usually have other disorders, for example:

  • Defects in the kidneys or urinary tract
  • There are abnormalities in the spine
  • Defect in the windpipe or trachea
  • Defect in the esophagus
  • Defects in the thigh or arm
  • Have Down syndrome
  • Duodenal atresia is the incomplete development of the first part of the small intestine
  • Congenital heart defects

You can consult a doctor if you have symptoms or signs that are not mentioned above. So, treatment efforts can be done immediately.

            Atresia ani is a disease with no known exact cause. This is caused by a genetic defect. This disorder occurs when your child is not born. It generally occurs from the 5th week to the 7th week of pregnancy. During this time, the child’s digestive system and anus begin to form.

Some of the risk factors that can increase the occurrence of atresia ani are:

  • Gender: this disease is more prone to be experienced by male babies
  • The presence of other birth defects
  • Use of steroid inhalers by the mother during pregnancy

The diagnosis of atresia ani is carried out by ultrasound. This aims to see any signs of blockage in the child’s digestive system and other disorders. If there is too much amniotic fluid, this is a sign of atresia ani or some other blockage in the baby’s digestive tract.

Atresia ani that occurs in infants is usually diagnosed after delivery by a physical examination. The doctor will check the baby’s stomach in order to see any symptoms of swelling and check the anal opening for any signs of abnormalities. X-rays and ultrasounds of the abdomen can be done to check for other problems. Performing tests is very important to find out the abnormalities associated with this condition so that proper treatment can be done. Some of the other tests include:

  • X-ray: detects spinal abnormalities
  • Spinal ultrasound: detects abnormalities in the spine
  • Echocardiogram: detects heart abnormalities
  • MRI: detects defects in the esophagus, such as fistula formation in the trachea or windpipe
