Filter by:This study aims to characterize the diagnostic performance of immunological testing of occult gastrointestinal bleeding in stool in the population aged over 75 years with iron deficiency anemia. As secondary objectives, the study aims to: - determine a threshold of positivity optimizing the immunoassay performance for the study population, in accordance with the probabilities of error (false positives, false negatives) and weights (defined by expert consensus) allocated to these errors. - Assess the benefit of a double measure of bleeding (two stools) by immunoassay compared to a single measure.
Capsule endoscopy (CE) is a safe and effective tool for the assessment of obscure gastrointestinal bleeding (OGIB). However, its real efficacy and its position in the diagnostic algorithm of OGIB vs. push enteroscopy (PE) remain unknown since in previous studies both techniques were performed in all included patients The purpose of this protocol is to conduct a randomized prospective controlled trial in patients with OGIB comparing a strategy based on CE or PE followed by the alternative exploration only when the first line exploration was negative. The main outpoint of this study concerns the diagnostic yield of the two explorations. Second endpoint concerns the clinical relevance of the two strategies tested (CE ± PE vs. CE ± PE) in terms of diagnostic yield, clinical outcome, therapeutic impact and added explorations
