Figure 6.

Successful challenge in a 58-year-old with history of prior colectomy with end ileostomy and small bowel resection for incarcerated hernia. Presentation CT with i.v. and no oral contrast (a, axial; b, sagittal) demonstrates dilated fluid-filled small bowel extending to a transition point adjacent to the ileostomy stoma (arrows). (c) 8-h AXR from the WSC challenge with mildly dilated and contrast opacified small bowel extending to the ostomy site (dashed arrow). (d) 24-h AXR with complete contrast clearance consistent with patency. AXR, abdominal radiographs; WSC, water-soluble contrast.
