Key Points

To compare the diagnostic yield of the M2A endoscopic capsule to video push-enteroscopy for obscure digestive bleeding.
Prospective study design including 60 patients with obscure digestive bleeding.
Double intestinal investigation using both techniques, analyzed blindly by separate examiners.
Diagnostic yield defined by detection of clinically relevant lesions.
Lesions detected in 43 patients with capsule revealing 21 exclusive detections (P=0.04).
Final diagnosis included high bleeding potential lesions in 28 patients and intermediate potential lesions in 15 patients.
Overall diagnostic yield with capsule was 67.2% compared to push-enteroscopy.
