Hirschsprung Disease on the NCLEX
No meconium in 48 hours, ribbon stools, enterocolitis danger, and pull-through surgical care.
Hirschsprung is the aganglionic colon that cannot pass stool. The newborn clue is one of the most reliable NCLEX facts there is.
Recognize it
Missing ganglion cells in the distal colon mean no peristalsis in that segment - stool stops above it. Newborn: failure to pass meconium within 24-48 hours plus abdominal distension, bilious vomiting, and feeding refusal. Older infant or child: chronic constipation, ribbon-like foul-smelling stools, distension, poor growth. Diagnosis: rectal biopsy showing absent ganglion cells is definitive.
Enterocolitis: the emergency
Hirschsprung-associated enterocolitis can be fatal. Watch for fever, explosive foul diarrhea, worsening distension, lethargy - report immediately. It can occur before or after surgical repair, so the warning signs are permanent parent teaching. Preoperative care: NPO if obstructed, IV fluids, measure abdominal girth at the umbilicus, monitor for perforation.
Surgery and after
Treatment is surgical removal of the aganglionic segment with a pull-through, sometimes staged with a temporary ostomy first. Post-op: NPO with NG until bowel function returns, strict I&O, incision and stoma care, pain control. Avoid rectal temperatures and rectal instrumentation. Teach ostomy care in stages and let parents demonstrate. Long term, some children have ongoing stooling or continence issues; enterocolitis vigilance continues.
Frequently asked
Healthy term newborn, no meconium at 30 hours?
Notify the provider. Most newborns pass meconium within 24-48 hours; delay raises Hirschsprung and other obstruction concerns.
Why ribbon stools?
Stool squeezes past the narrowed aganglionic segment, which molds it thin. Combined with chronic constipation it points to Hirschsprung.
What differentiates it from meconium ileus?
Meconium ileus is thick meconium blocking the ileum and is strongly linked to cystic fibrosis. Hirschsprung is absent nerve cells in the colon. Both delay meconium; workups differ.
