Colonic Acquired Fistulae: The Potential of CT Colonography

The diagnosis of colonic fistulae is crucial in defining the best therapeutic approach. Fistulae can be suspected from clinical history or spe-cific 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 Colonog-raphy 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.(c) 2022 The Association of University Radiologists.

The diagnosis of colonic fistulae is crucial and imaging plays a key role in confirming the diagnosis. Previous studies described conventional methods like barium studies, but newer tests like intestinal ultrasound, CT, and MR have shown promise. CT Colonography is the best radiologic test for evaluating the colon, but its role in colonic fistulae is limited. This paper aims to highlight the potential of CT colonography in evaluating patients with suspected colonic fistulae.
