As the first CT did not definitively identify an enterocutaneous fistula, he was recalled for a repeat CT with oral contrast, but no intravenous contrast. 800 ml of 5% Gastrografin was administered slowly over 60 minutes prior to imaging. The contrast opacifies the stomach and small bowel and delineates a fistula to the anterior abdominal wall. Contrast has pooled on the surface of the dehiscent anterior abdominal wall, and is within the stoma bag used to drain the wound. The fistulous loop is ileal.
