Overview

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

X-Ray

Abdominal plain x-ray findings associated with Hirschsprung's disease may include:

• Radiography performed in children with Hirschsprung's disease yields findings similar to those in other forms of distal small intestine obstruction; variable gaseous distention of the colon and small bowel, often with air-fluid levels.
• The colon is usually difficult to identify, accurately; 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.
