Answer week 2

Answer: Hirschsprung disease

Case Discussion:

Barium enema images demonstrate a reduced caliber rectum (the rectum is smaller than the sigmoid and descending colon). A transition point is seen at the sigmoid colon.

Hirschsprung disease is the most common cause of neonatal colonic obstruction. It is commonly characterized by a short segment of colonic aganglionosis affecting term neonates.
