Diagnosis of Early Gastric Cancer by Magnifying Endoscopy with NBI from Viewpoint of Histological Imaging: Mucosal Patterning in terms of White Zone Visibility and Its Relationship to Histology

Table 1

Relationship between white zone distinctiveness and length of the intervening part. The lengths of the intervening parts in areas where the white zones were distinct, visible but nondistinct, and invisible were 136 ± 46 μm, 74 ± 17 μm, and 82 ± 34 μm, respectively. The length of the intervening parts in the surrounding gastritis mucosa was 127 ± 46 μm. The lengths of the intervening parts of lesions showing a distinct white zone and those in the surrounding gastric mucosa were significantly longer than those in areas with a visible but nondistinct or a invisible white zone (𝑃<0.05).

Distinctness of white zone	The length of; intervening parts
Lesion with distinct white zone	136 ± 46 μm*
Lesions with visible, but nondistinct; white zone	74 ± 17 μm**
Lesion with invisible white zone	82 ± 34 μm**
Surrounding gastric mucosa	127 ± 46 μm*
