The anus is the hole in your bottom where poop (stool) comes out. The rectum is the end of the large intestine that attaches to the anus.
Anorectal malformations are birth defects of the anus and the rectum.

Sometimes, for severe problems, doctors first do a temporary colostomy. Doctors make a hole in the large intestine and connect it to a hole in the belly. Your baby's poop goes out the hole into a bag until your baby has grown big enough to have another operation to fix the anorectal malformation and close the colostomy.
