In brief: Lack of anal opening

An imperforate anus is a congenital anomaly in which a baby is born without an anal opening altogether, one that is too small, or one that is located in the wrong place (for example, opening into the vagina in a girl or into the bladder in a boy).
It is definitively repaired with surgery to create a good anal opening in the right place. Sometimes, a colostomy is done first.

The outcome for IA depends on the level of the defect and the quality of the surgery. The best outcomes are for girls with low defects

In brief: Terminology issues

The lower colon forms from a solid tissue structure that develops an inner cavity.
It grows down to where the anal opening should be. As the internal tissue meets the outside skin from the inside, the skin barrier between the structures dissolves and the anus "perforates". If the internal structure does not come close to the skin, or the outer skin stays separate, the hole cannot form. (imperforate).
