Overview

Other Imaging Findings

Colonic Marker Studies

Colonic marker transit studies are useful to distinguish colonic inertia from functional outlet obstruction etiologies. In this test, the patient swallows a water soluble bolus of radio-opaque contrast and films are obtained 1, 3 and 5 hours later. Patients with colonic inertia show the marker spread the large intestines, while patients with outlet obstruction exhibit show accumulations of markers in some places.

Colonoscopy

A colonoscopy can also be used to rule out mechanical obstructive causes.

Anorectal manometry

Anorectal manometry may help to differentiate acquired from congenital forms.

Rectal Biopsy

Rectal biopsy is recommended to make a final diagnosis of Hirschsprung disease.
