Anal atresia is a congenital abnormality in which there is no opening at the end of the digestive tract, where the anus normally is. It is part of a wider spectrum of abnormalities involving the anus and last part of the bowel, the rectum. Anorectal malformations (ARMs) can range from mild abnormalities with only a thin membrane covering the anus to more severe abnormalities with the rectum ending high up in the belly. The rectum may be connected to the skin or other parts of the body, such as the bladder or the vagina, through a channel, called a fistula.
