(a) Schematic diagram of the microvascular architecture and the microsurface structure of the normal gastric fundic gland mucosa corresponding to the surface morphology as visualized by magnifying endoscopy (ME) with narrow-band imaging (NBI). The microvascular architecture is formed by the capillaries and collecting venules. The morphology of each capillary is that of a polygonal closed loop. These loops anastomose repeatedly with each other, forming a regular honeycomb-like subepithelial capillary network pattern. The microsurface structure is made up of the marginal crypt epithelium/white zone (MCE/WZ), and the intervening part in between. The epithelial morphology is visualized as a semitransparent white belt-like structure (the MCE/WZ), showing a circular or oval shape at the center of which lies the crypt opening. (b) ME with NBI of normal fundic gland mucosa. (Muto M. Digest Endosc 2016)

(a) Schematic diagram of the microvascular architecture and the microsurface structure of the normal gastric pyloric gland mucosa corresponding to the surface morphology as visualized by magnifying endoscopy (ME) with narrow-band imaging (NBI). The microvascular architecture is formed by capillaries and collecting venules, but the latter are rarely observed from the mucosal surface. The morphology of each capillary is that of coil-shaped open loops. The mucosal surface structure is made up of the marginal crypt epithelium/white zone (MCE/WZ) and the intervening parts surrounded by MCE/WZ. The MCE/WZ morphology usually shows polygonal structures but may be curved or linear. (b) ME with NBI of normal pyloric gland mucosa. (Muto M. Digest Endosc 2016)
