Capsule Endoscopy vs. Push Enteroscopy in Occult Gastrointestinal Bleeding OGIB

This was a prospective randomized multicentric study. After the screening visit, eligible subjects were randomly assigned to be explored by CE or PE (first line exploration). The alternative exploration was only performed if no diagnosis was evidenced by the examination assigned by randomization. An independent staff member assigned subjects in 1:1 ratio between CE and PE strategies with stratification for overt and occult bleeding and centers according to consecutive number that were kept in serialized sealed opaque envelopes. After the completion of these explorations, the patients returned at month 3, 6 and 12 thereafter. At each visit, clinical evaluation and laboratory tests were performed and patients were managed according to published recommendations2 (AGA medical position). The first line exploration as well as the alternative exploration could be done during the one year follow-up period only in case of severe relapse of OGIB or necessity to perform biopsies or a therapeutic procedure.

Inclusion criteria

• Patients may suffer from episodes of active bleeding within the last 6 months or chronic iron-deficiency anemia (hemoglobin < 10 g/dl).
• A gynecologic or proctologic bleeding source had to be excluded.
• All patients had to have negative workup including upper gastrointestinal endoscopy, colonoscopy and small-bowel barium series or computed tomography enteroclysis.
• Medical reports and/or the imaging documents were available and reviewed in all patients. Usually these investigations were repeated several times before inclusion.
• Abdominal angiography was only performed when there were signs of active bleeding during the diagnostic work-up (n = 3). Meckel scintigraphy was usually carried out in patients under 30 years of age (n = 14).
