Summary

Anatomical components of morphological analyses using the VS classification system
V components: regular, irregular, or absent
- Capillaries
- Collecting venules (CVs)
- Microvessels (cannot be identified as capillaries or CVs)
S components: regular, irregular, or absent
- Marginal crypt epithelium (MCE) (surface epithelium lining the gastric crypts)
- Surface epithelium covering the intervening part (IP) (usually not visualized, recognized as the area between MCE and MCE)
- Crypt openings (COs)
- Light blue crest (LBC) (brush border)
- White opaque substance (WOS)
Interpretation integrating the combined morphology of V and S components
- Concordance between V and S: concordant, discordant, or indeterminate

9.1 Principles of the Proposed Diagnostic System

When we combine magnified endoscopic (ME) examination of the gastric mucosa with narrow-band imaging (NBI), in addition to a variety of mucosal subepithelial microvascular architectures (V, microvascular pattern), we can visualize the mucosal microsurface pattern (S, microsurface pattern). I have proposed a new diagnostic system, the VS classification system, for the systematic interpretation of magnified endoscopic findings [1–4]. The principles of this diagnostic system are to assess the microvascular pattern and microsurface pattern separately, and then integrate both findings in accordance with consistent diagnostic criteria [1–4].
