Causes
• HSD
• ARM
• Idiopathic constipation

Hirschsprung’s Disease
• It is a form of chronic intestinal obstruction caused by congenital absence of ganglion cells in both the intermuscular and submucosal plexuses.

Pathologic Anatomy
• Distal Narrow Segment: Aganglionic
• Proximal Dilated Segment: Ganglionic.
• Transitional Zone: Hypoganglionic.
![Page 5: Constipation&incontinence](https://reader036.fdocuments.in/reader036/viewer/2022081602/556eb655d8b42aa32b8b4a84/html5/thumbnails/5.jpg)
Extent of Aganglionosis• Short segment (75%):
Rectosigmoid.
• Long segment (20%): Descending colon.
• Total Colonic (5%): Colon and parts of small intestine.

Clinical Picture
• Age: 50% neonates, 45% up to 2 yrs,
5% > 2yrs.• Failure to pass
meconium within 48hrs
• Abdominal distension.• Constipation.

D.D:Functional ConstipationTreatment
• Initial evacuation of retained stools by enemas.
• Regular evacuation of rectum by suppositaries.
• Stool softners.• Treatment of anal fissurs.• Dietary.• Toilet training.

CONCLUSION
• Early detection, proper diagnosis & management of constipation in children gives excellent results.
• Hirschsprung’s disease should be suspected in cases of constipation resisting ordinary treatment.
