Anorectal malformation

Anorectal malformations are birth defects where the anus and rectum (the lower end of the digestive tract) do not develop properly.

During a bowel movement, stool passes from the large intestine to the rectum and then to the anus. Muscles in the anal area help to control when a bowel movement occurs. Nerves in the area help the individual sense the need for a bowel movement and also stimulate muscle activity.

With an anorectal malformation, several abnormalities can occur, including the following: The anal passage may be narrow.

• A membrane may be present over the anal opening.
• The rectum may not connect to the anus (imperforate anus).
• The rectum may connect to a part of the urinary tract or the reproductive system through an abnormal passage called a fistula.

A comprehensive level of care

Anorectal malformations can be complex issues. The General Surgery Program at Boston Children's Hospital evaluates and treats infants afflicted with these types of birth defects.
