Design outcomes

Primary

MeasureTime frame
Gastric biopsied specimens will be taken from the green change mucosa suspicious of intestinal metaplasia by BLI images, compared with white light images. Similarly, specimens will be taken from brown change mucosa suspicious of non-intestinal metaplasia. Based on the pathological findings, sensitivity, specificity and accuracy will be evaluated.

Secondary

MeasureTime frame
Based on histological assessment of endoscopically resected specimens, the usufulness of BLI will be evaluated about the extent of tumor by color contrast between the tumor and the surrounding mucosa. In additon, the color difference will be measured using a color space International Lighting Commission recommended in 1976 in order to quantify such color contast and assess visibility of tumors by BLI.
