DIGESTIVE HAEMORRHAGE: PLACE OF SCINTIGRAPHY COUPLED WITH TECHNICIUM 99

The acute gastrointestinal bleeding is associated with a high mortality risk.Thecause of the bleeding is usually identified with an upper gastrointestinal endoscopy and a colonoscopy. Rarely, the etiology of hemorrhage is obscure and not found by endoscopy. The purpose of this work is to evaluate the contribution of single-photon emission computed tomography (SPECT)/CT) in the diagnosis and management of obscure gastrointestinal bleeding, based on a clinical case of a64-year-old patient, presenting with melaenas 10 days prior to her admission, requiring multiple blood transfusions. An upper gastrointestinal endoscopy, a colonoscopy, a capsule endoscopy and an abdominal angio-scan, did not found any active origin of the bleeding. The Tc99m red blood cells scintigraphy showed an active bleeding in the left hypochondrium. The SPECT/CT confirmed the diagnosis and guided the treatment by electrocoagulation. The Tc99m red blood cells scintigraphy is a useful diagnostic tool in objectifying a gastrointestinal bleeding without being able to…
