Background |
Small-bowel lesions responsible for obscure GI bleeding are often accompanied by vascular abnormalities. Image-enhanced capsule endoscopy could be advantageous in detecting these abnormalities.
Objective |
To evaluate the image representation performance of the contrast capsule.
Design |
Feasibility study.
Setting |
University hospital.
Patients and Interventions |
Consecutive patients with obscure GI bleeding swallowed the contrast capsule.
Main Outcome Measurements |
Image representation performance of the contrast capsule and the appearance of small-bowel lesions in image-enhanced capsule endoscopy.
Results |
Twenty 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.
Limitations |
Small, single-center, nonrandomized study.
Conclusion |
This 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.
