Imperforate Anus/Absent Anal Opening Treatment Delhi, India
Imperforate anus or absent anal opening, also called anorectal malformation, is a birth defect that happens during the development of baby in early in pregnancy, when the baby is still developing. In this defect, the baby’s anal opening (where stool exits) and the rectum (the last part of the large intestine), do not develop properly, preventing the child from to pass stool.

The condition affects one in 5,000 babies, and it is slightly more common in males than in females. In a baby with anorectal malformation, any of the following can happen:

The anal opening is too small or in the incorrect location
The anal opening is absent and the rectum enters other parts like urethra, the bladder, vestibule or vagina, which can lead to infections and bowel obstruction.
The anal opening may be absent and the rectum, reproductive system, and urologic system form a single common opening called a cloaca, where both urine and stool are passed.
At birth, doctors check the position and size of anal opening. New-borns pass their first stool within 48 hours of birth, so internal malformations are detected quickly. If an issue is found, we do a number of tests to better understand the problems and develop a long-term plan for the best outcome. This problem can be associated with other malformations. Various tests which are performed include:

X-rays of the abdomen to show how far the rectum reaches, and to see if there are any problems with the way the lower backbone has developed.
Abdominal ultrasound to find any problems in kidney.
Spinal ultrasound or MRI to look at the spine for a tethered spinal cord, which can cause neurological problems, such as incontinence and leg weakness as the child grows.
Echocardiogram to find heart defects.
These malformations will always require surgical repair by pediatric surgeon in single or multiple stage, but the exact procedure will depend on the type and severity of the defect, any associated health conditions, and the child’s overall health. Depending on the type and severity these babies may require a stoma formation (a temporary diversion of stools from abdominal wall).

Even though corrective surgery may restore some function, important nerves and muscles that tell your child when the rectum is full of stool and help keep the contents inside may be missing or damaged, so we start a bowel management program when they reach toilet-training to help them become clean.
