Hirschsprung Disease : Radiology

Post evacuation barium enema film demonstrates the transition point between sigmoid and descending colon more obviously. The denervated segment (rectum and distal sigmoid colon in this case) appears narrowed as a result of spasm. The appearance is typical of short segment Hirschsprung disease.
