Hirschsprung’s Disease
A 3-day-old male neonate is brought to the neonatal unit with concerns of not passing meconium since birth. The mother reports that the baby has been feeding poorly and has developed abdominal distension. Over the past 24 hours, the infant has been increasingly irritable and had a few episodes of bilious vomiting.
On physical examination, the neonate’s abdomen is distended and tense. Rectal examination reveals an empty rectum, and after withdrawal of the finger, there is an explosive release of stool and gas. Further evaluation with a contrast enema shows a transition zone between the normal and narrowed, aganglionic segment of the distal colon.
A rectal biopsy is performed, confirming the absence of ganglion cells in the affected bowel segment, consistent with a diagnosis of Hirschsprung’s disease. The infant is scheduled for surgical resection of the aganglionic segment, followed by a pull-through procedure, with a good prognosis expected after surgery.
