BackgroundSmall-bowel lesions responsible for obscure GI bleeding are often accompanied by vascular abnormalities. Image-enhanced capsule endoscopy could be advantageous in detecting these abnormalities.ObjectiveTo evaluate the image representation performance of the contrast capsule.DesignFeasibility study.SettingUniversity hospital.Patients and InterventionsConsecutive patients with obscure GI bleeding swallowed the contrast capsule.Main Outcome MeasurementsImage representation performance of the contrast capsule and the appearance of small-bowel lesions in image-enhanced capsule endoscopy.ResultsTwenty patients (16 males and 4 females) underwent capsule endoscopy during the study period. Small-bowel abnormality was detected, including 5 cases of multiple erosions or ulcers, 1 case of Peutz-Jeghers syndrome, and 1 case of angiectasia. The contrast capsule visualized the lesions with high vascularity in a dark green color with a strong color contrast compared with the surrounding normal mucosa, which appeared as a brownish color.LimitationsSmall, single-center, nonrandomized study.ConclusionThis feasibility study demonstrated the image representation characteristics of the contrast capsule. The diagnostic yield of this technology should be investigated in a future randomized trial.
