 Here, we report the typical magnified endoscopic findings of normal gastroduodenal mucosa and describe the nature of each endoscopic finding in relation to anatomical findings.

 Regarding normal gastric fundic gland mucosa, the microvasculature showed a regular honeycomb-like subepithelial capillary network(SECN)pattern with the presence of a regular collecting venule(CV)pattern. The microsurface structure showed a regular oval crypt-opening(CO)pattern alongside a regular oval marginal crypt epithelium(MCE)pattern. Regarding normal gastric pyloric gland mucosa, the microvasculature showed a regular coil-shaped or reticular SECN pattern with the absence of a regular CV pattern. The microsurface structure showed a regular curved-or polygonal MCE pattern. Regarding normal duodenal mucosa, the microvasculature was composed of a regular leash-like villus-SECN(V-SECN)pattern with a single villus venule. The microsurface comprised of regular curved-or oval-shaped marginal villus epithelium(MVE). All magnified endoscopic findings were closely related with anatomical structures demonstrated using scanning electron microscopy of vascular casts and mucosal surface as well as with histological findings.

 Considering that modern magnifying endoscopes possess sufficient resolving power for the visualization of micro-anatomical components, it is essential to employ accurate anatomical terms during the analysis of magnified endoscopic findings.
