Key takeaways
- Hirschsprung disease results from absent ganglion cells in the distal colon, causing functional obstruction in newborns and infants.
- Diagnosis requires rectal biopsy showing absence of ganglion cells; contrast enema may show transition zone between normal and aganglionic bowel.
- Definitive treatment is pull-through surgery to remove aganglionic segment and restore bowel continuity with normal innervated colon.
- Postoperative complications include enterocolitis, stricture formation, and bowel dysfunction requiring long-term follow-up and management.
- Early recognition and surgical intervention improve outcomes; delayed diagnosis increases risk of toxic megacolon and perforation.
