Doctors will typically classify malformations based on where the rectum (the lower part of the intestine) ends within the abdomen, and if there is a fistula – an abnormal channel that develops between organs that can cause stool to pass through or into parts of the abdomen.
Typically, lower malformation types can be repaired with one surgery, and children can be expected to recover good bowel control. Children with higher types require more procedures, such as a colostomy at first, with reconstruction at 3 to 6 months, and will typically have more challenges gaining bowel control.
