Summary

When performing screening endoscopy, small focal gastric lesions are frequently encountered. Novel techniques in endoscopy, such as magnifying endoscopy (ME) with narrow-band imaging (NBI) and chromoendoscopy with acetic acid-indigocarmine mixture (AIM), are developing to enhance images of gastrointestinal tumor. Furthermore, observation of the microstructures of gastric mucosa by ME, including microvascular pattern and microsurface pattern, has been proposed in the recognition of early gastric cancer (EGC).

This study is based on the hypothesis as follow:

1. The microvascular structure could be clearly observed with magnifying endoscopy enhanced by narrow-band imaging (ME-NBI).
2. The microsurface architecture could be clearly observed with magnifying endoscopy enhanced by acetic acid-indigocarmine mixture (ME-AIM).
3. Enhanced ME (combining ME-NBI and ME-AIM), as compared to white-light endoscopy (WLE), has higher sensitivity and specificity for the differential diagnosing small focal gastric lesions.
