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 2

Relationship between white zone distinctiveness and crypt depth. The depths of crypts in areas where the white zones were distinct and those in lesions where the white zones were nondistinct or invisible were 182 ± 52 μm and 81 ± 25 μm, respectively. The depth of crypts in the surrounding gastric mucosa was 171 ± 42 μm. The crypts in lesions showing a distinct white zone and those in the surrounding gastric mucosa were significantly deeper than those in lesions with a nondistinct or invisible white zone (𝑃<0.01).

Distinctness of white zone	The depth of crypts
Lesion with distinct white zone	182 ± 52 μm*
Lesions with nondistinct or invisible white zone	81 ± 25 μm**
Surrounding gastric mucosa	171 ± 42 μm*
