Significance of scintigraphy for the localisation of obscure gastrointestinal bleedings

Abstract

Our results show that scintigraphy and scintigraphy with heparin provocation tests are reliable procedures. They enable a reliable localisation in about half of the obscure GI-bleeding cases. Scintigraphy is superior to angiography in locating a bleeding. It is shown that even in the age of video capsule endoscopy and double-balloon enteroscopy, scintigraphy provides a reliable and directed localization of GI bleeding and offers carefully targeted guidance for other procedures.
