Pseudo-obstruction of the colon.

Abstract

Pseudo-obstruction of the colon is a rare form of diffused or segmental dilatation of the colon nonassociated with an obstructive lesion. It usually accompanies or follows other major illnesses in elderly patients. The abdominal radiographs are very helpful in differentiating this form of ileus from a chronic mechanical obstruction of the colon and in evaluating its complications. The abdominal radiographs of 14 patients with pseudo-obstruction of the colon were reviewed, and the radiographic findings associated with this condition were evaluated.
