title: Radionuclide enemas for localization of gastrointestinal bleeding sites.
abstract: The anatomical site of gastrointestinal bleeding may not be determined accurately with a scintigraphic bleeding scan. A case in which a radionuclide enema following a positive scintigraphic bleeding scan helped to guide the surgeon to the appropriate bleeding site, is presented. The radionuclide enema also obviates the need for barium examinations that would interfere with subsequent angiography.
