title: [Scintigraphy of bleeding. The diagnostic value based on a 10-year period].
abstract: The purpose was to examine the diagnostic value of 99mTc-labelled red blood cell scintigraphy for detection of gastrointestinal haemorrhage. In a retrospective investigation 85 patient files over a 10 year period (1.1.1984-31.12.1993) were evaluated. Data regarding the patients' clinical condition, number of blood transfusions, findings with angiography, gastroscopy, colonoscopy, proctoscopy, operation, x-ray of colon and autopsy were registered. A bleeding site was localized in 52% of the scintigraphies. Among these patients the scintigraphic localization was confirmed or made "very possible" in 65% by operation, autopsy or one of the other mentioned diagnostic modalities. Among the 25 operated patients the localization of the bleeding site was confirmed in 19 patients. In 40 patients with a "negative" scintigraphy a bleeding site was found in 10 patients 1-18 days after the scintigraphy by operation or one of the listed diagnostic modalities. It is concluded that 99mTc-labelled red blood cell scintigraphy is a valuable diagnostic tool for identification of acute gastrointestinal haemorrhage. Operation after scintigraphic guidance is well indicated. A "negative" scintigraphy can only exclude ongoing bleeding from the gastrointestinal tract.
