[Scintigraphy in the diagnosis of intestinal hemorrhage]

13 patients with gastrointestinal hemorrhage underwent a scintigraphic examination to localize the bleeding. In 6 patients Tc-99m labeled red blood cells, in 7 patients Tc-99m sulfur colloid were used. Scintigraphy could demonstrate an intestinal bleeding in ten patients, in whom the conventional examinations, and among them 7 abdominal angiographies had failed. 5 of them had to be operated after that, whereby the scintigraphic findings were verified. One of the three patients with negative scintigraphy had to undergo an operation because of continuous bleeding. The methods of scintigraphy and their indication in gastrointestinal hemorrhage are discussed.
