[Scintigraphic detection of gastrointestinal hemorrhage. Value and limitations].
A technetium-99m labelled red blood cell scintigraphy was performed in 51 patients with an unexplained gastro intestinal bleeding. Static images were acquired on the injection day then at 24 hours. Forty one patients had a positive scintigraphy. In 13 patients with a positive scintigraphy, on the injection day (5 cases) and later (8 cases), no intestinal bleeding was identified in spite of further investigations guided by scintigraphy. In 24 patients, with a positive scintigraphy on the injection day (20 cases) and later (4 cases), an intestinal lesion was identified and treated; data were confirmed in 19 cases: there were 15 colon lesions, localized on caecum in 10 cases and 4 small bowel lesions. Clinical value and limitations of the investigation are discussed. The scintigraphic localization is usually accurate if the abnormal focus activity is noticed on the injection day. It helps to guide further investigations of the bleeding site. This non invasive method should be performed more quickly to help to localize intestinal bleeding which poses a diagnostic problem.
