Abstract
The fine gastric mucosal patterns of the gastric mucosal surface were observed using the magnifying endoscope (FGS-MLII) at a magnification of about 30. For simplification, new classification was made on the fine gastric mucosal patterns in the following ways; A, AB, B, BC, C, CD, D. The A has only dotted gastric pits. The B, C and D have broken, continuous and mesh-like linear grooves respectively. The AB, BC and CD are mixed patterns of A-B, B-C and C-D. At first, the gastric mucosa with atrophic gastritis was observed by magnifying endoscopy with dye-spraying techniques, such as the endoscopic congo red test and the methylene blue stain. The A was seen on the normal f undic mucosa and the B was mainly observed on the intermediate zone (atrophic border). The C was seen on the pyloric mucosa with or without intestinal mataplasia. The D was often seen on the regenerated mucosa, which showed markedly atrophic pyloric mucosa.
