Hirschsprung’s Disease

What Is Hirschsprung’s Disease?

Hirschsprung’s disease is a congenital condition in which nerve cells (ganglion cells) are missing from parts of the large intestine, preventing normal movement of stool. Without these nerve cells, the affected segment of the colon cannot relax, causing a blockage and difficulty passing stool. This condition is typically diagnosed in newborns or young children, though milder forms may not be discovered until later in childhood.

Timely diagnosis and surgical treatment are critical to relieve symptoms, prevent complications, and allow for healthy bowel function as the child grows.

Signs and Symptoms

Symptoms can vary based on age and how much of the colon is affected, but common signs include:

  • Newborns who fail to pass meconium within 48 hours of birth
  • Chronic constipation or abdominal swelling
  • Vomiting, sometimes with a green (bilious) color
  • Poor feeding or failure to thrive
  • Explosive stools following a rectal exam
  • Enterocolitis (severe inflammation of the colon) in some cases

Diagnosis

Diagnosis is based on a combination of physical examination, imaging, and tissue testing:

  • Abdominal X-ray or contrast enema to look for a blockage or narrowed segment
  • Anorectal manometry to measure muscle function and nerve reflexes
  • Rectal biopsy is the definitive test to confirm absence of ganglion cells

Treatment Options

The primary treatment for Hirschsprung’s disease is surgery. The goal is to remove the affected portion of the colon and restore normal bowel function. Surgical options may include:

  • Pull-through surgery — the most common approach, where the diseased segment is removed and healthy bowel is reconnected to the anus
  • Staged surgery — may involve a temporary colostomy followed by a pull-through procedure once the child stabilizes

Most children go on to have good long-term outcomes, though some may require ongoing support for constipation, soiling, or enterocolitis prevention.

Frequently Asked Questions

It is a congenital condition caused by incomplete development of nerve cells in the colon during fetal growth.

A rectal biopsy is the gold standard for diagnosis. Additional tests like contrast enema and manometry may help support the diagnosis.

Yes, Hirschsprung’s disease is typically treated successfully with surgery. Most children improve significantly afterward.

Without treatment, children are at risk of severe constipation, bowel obstruction, and life-threatening enterocolitis.

Many children do well, though some may need support for ongoing constipation or stool control issues, especially in the early years following surgery.
