Overview

X-ray abdomen is the primary modality of choice in diagnosing Hirschsprung's disease. Findings include decreased bowel caliber of the involved segment along with colonic distension.

X-Ray

Abdominal Xray findings associated with Hirschsprung's disease may include:

• Radiography performed in children with Hirschsprung disease yields findings similar to those in other forms of low small bowel obstruction: variable gaseous distention of the colon and small bowel, often with air-fluid levels.
• The colon is usually difficult to identify accurately, and gas is usually absent in the rectum.

Moderate distention of the descending colon with smooth delineation, this distension is secondary to short markedly stenotic segment seen in the proximal sigmoid colon as well as reduced calibre of the remaining sigmoid colon and rectum.
