Hirschsprung's disease

Also called Congenital aganglionic megacolon

Hirschsprung's disease is a rare condition, present from birth, where nerve cells are missing from the end of the bowel. Without them, the bowel cannot push poo along, so it builds up and causes a blockage. It is usually found soon after birth, but milder cases may not be noticed until later in childhood.

What it is

It is treated with surgery to remove the affected part of the bowel. Some children need a temporary stoma.

Most children do well after surgery, though some have constipation or soiling for a while.

Common signs

  • A newborn not passing meconium (first poo) within 48 hours
  • Swollen tummy
  • Vomiting green fluid
  • Long-term constipation in older children
  • Poor growth

How it is usually diagnosed

  • Examination
  • X-rays
  • A rectal biopsy

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Biopsy results
  • Surgery and discharge letters
  • Bowel management plans
  • Paediatric surgery follow-up notes

Questions to ask your doctor

  • What surgery will my child need?
  • What should we watch for after the operation?
  • What support is there for bowel problems later?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • A child with a swollen tummy, fever, smelly diarrhoea or green vomiting: call 112, it may be a serious bowel infection
