Value of CT in localizing site of gastrointestinal hemorrhage following negative angiography.

This case report of severe gastrointestinal (GI) bleeding demonstrates the utility of computed tomography (CT) in localizing such hemorrhages when all other diagnostic modalities have been exhausted. All previous studies in this case were nondiagnostic. However, abdominal CT performed without the benefit of oral contrast but immediately following negative angiography was useful in directing the surgeon to the region of hemorrhage by documenting the presence of focally dense intraluminal contrast within the small bowel loops.
