Why Is an Ostomy Needed for Hirschsprung Disease?

Learning your baby needs an ostomy bag when you were hoping for a single surgery can be incredibly overwhelming and scary. While many babies with Hirschsprung disease can have a single “pull-through” surgery, some studies show that roughly a third of patients need a staged approach ^[1]. In a staged approach, the surgeon first creates a temporary ostomy (a small surgical opening in the belly where stool safely empties into a pouch). This is necessary when it isn’t safe to perform the main pull-through right away because the baby is too sick, the bowel is stretched out, or there is a severe infection. The ostomy acts as a protective safety valve, allowing your child to grow, bond with you, and heal before the next surgery.

A staged approach usually involves two or three separate surgeries over the course of several weeks to a few months: first creating the ostomy, then the main pull-through surgery, and sometimes a final, smaller surgery to close the ostomy.

Giving the Healthy Bowel Time to Heal

In Hirschsprung disease, the section of the intestine missing nerve cells creates a roadblock. Because stool cannot pass naturally, the “healthy” bowel above the blockage works overtime trying to push things through. This causes the healthy intestine to become massively swollen, stretched, and thickened ^[2][3].

If a surgeon tries to pull this stretched-out bowel down to the anus during a single surgery, the connection is at high risk of leaking or not working properly. By creating a temporary ostomy above the blockage, stool is safely diverted into a bag. This allows the swollen, overworked healthy bowel to empty completely, rest, and shrink back to its normal size and strength ^[2][3]. Once the bowel has recovered, the surgeon can safely perform the pull-through connection.

Clinical Reasons for a Staged Surgery

Your child’s surgical team might decide an ostomy is the safest first step for several important reasons:

• Managing Infection (HAEC): Hirschsprung-associated enterocolitis (HAEC) is a severe infection of the intestines. If a baby develops severe HAEC, the bowel becomes too inflamed for a safe pull-through. An ostomy quickly drains the infection and relieves the dangerous pressure, allowing the bowel to heal ^[4][3].
• Helping Very Sick or Premature Babies: Premature infants or babies who are medically unstable—such as having low blood protein levels, which are critical for tissues to heal properly—may not be strong enough for a major reconstructive surgery. An ostomy is a quicker, safer procedure that solves the immediate blockage, giving your baby time to gain weight and get stronger ^[5][6][7].
• Complex or Long-Segment Disease: If the missing nerve cells extend high into the colon or affect the entire colon, the surgical risks are higher. Surgeons often prefer a staged approach for these complex cases to ensure the safest possible outcome ^[2][4].
• Preventing or Treating a Tear: In critical situations, backed-up pressure can cause a tear (perforation) in the intestine. An immediate ostomy treats this emergency safely and stops stool from spilling into the abdomen ^[4][3].

By splitting the treatment into stages, the surgical team prioritizes your baby’s immediate safety while setting the stage for the best long-term outcome.

Living with a Temporary Ostomy

It is completely normal to feel anxious about caring for your baby’s ostomy. However, having an ostomy does not mean you cannot interact with your child normally. You can absolutely still hold, cuddle, bathe, and bond with your baby just as you would otherwise.

Before you go home from the hospital, a specialized nurse (often called a wound or ostomy nurse) will sit down with you and teach you exactly how to manage the bag, change the supplies, and care for your baby’s skin. You will not have to figure this out alone, and they will make sure you are comfortable and confident before you leave.
