  • 8. Peer Review

    All papers submitted to Gut and Liver are reviewed by the editorial team before being sent out for an external peer review to rule out papers that have low priority, insufficient originality, scientific flaws, or the absence of a message of importance to the readers of the Journal. A decision about these papers will usually be made within two or three weeks.
    The remaining articles are usually sent to two reviewers. It would be very helpful if you could suggest a selection of reviewers and include their contact details. We may not always use the reviewers you recommend, but suggesting reviewers will make our reviewer database much richer; in the end, everyone will benefit. We reserve the right to return manuscripts in which no reviewers are suggested.

    The final responsibility for the decision to accept or reject lies with the editors. In many cases, papers may be rejected despite favorable reviews because of editorial policy or a lack of space. The editor retains the right to determine publication priorities, the style of the paper, and to request, if necessary, that the material submitted be shortened for publication.

Abstract

Background/Aims: Video capsule endoscopy (CE) can provide a negative result despite the presence of clinically significant small-bowel lesions. We therefore performed a prospective study to elucidate whether repeated back-to-back CE increases the diagnostic yield over a single CE in patients with obscure gastrointestinal bleeding (OGIB). Methods: Sixteen patients with OGIB were prospectively enrolled and underwent back-to-back CE investigation with a 24-hour interval. All CE videos were interpreted by two experienced readers at a maximum 15 frames/second in a random order. Results: The diagnostic yield of the single CE was 37.5% for the first CE, 43.8% for the second CE, and 62.5% for the back-to-back CE. The overall mean lesion-detection rates of the first and second CEs were 42.2% and 64.6%, respectively. The bowel preparation status of the second CE was improved in 37.5% and unchanged in 62.5% of cases as compared with that of the first CE. Conclusions: These results indicate that back-to-back CE may increase the diagnostic yield and lesion-detection rate over a single CE in patients with OGIB. Therefore, if the first CE is not diagnostic in a patient with OGIB, repeat back-to-back CE may be considered as a candidate for further workup. (Gut Liver 2010;4:54-59)
