Colonic Acquired Fistulae: The Potential of CT Colonography.

ABSTRACT

The diagnosis of colonic fistulae is crucial in defining the best therapeutic approach. Fistulae can be suspected from clinical history or specific symptoms, but imaging plays a key role in confirming the diagnosis. Previous studies described conventional studies with barium as methods of choice for the diagnosis; more recently intestinal ultrasound, CT and MR have been considered promising tests. CT Colonography is the best radiologic test to evaluate the colon, but only few case reports described its role in this setting. Aim of this paper is to highlight the potentials of CT colonography in evaluating patients with suspected colonic fistulae.
