Overview

Barium enema is the mainstay of Hirschsprung’s disease diagnosis. Barium enema findings suggestive of Hirschsprung's disease include a transition zone between the narrow and dilated portions of the colon in the shape of an inverted cone, which is the most characteristic radiologic finding.

Other Imaging Findings

Barium Enema

  • Barium enema studies demonstrate patency of the colon, which is short but usually normal in caliber.
  • A transition zone between the narrow and dilated portions of the colon in the shape of an inverted cone is the most characteristic radiologic finding.
  • When this transition zone is observed, the examination should be discontinued because filling of proximal dilated bowel beyond the transition zone may lead to impaction.
  • Radiologic diagnosis of total colonic aganglionosis is difficult. Findings from barium enema examination may be normal or may show a short colon of normal caliber, microcolon, or a transition zone in the ileum.[1]
