We performed magnifying endoscopy for patients with suspected gastric diseases. Among these patients, 67 patients with early gastric cancer and 31 benign gastric diseases were enrolled in this study. The patients with early gastric cancer included 46 differentiated tubular adenocarcinoma (33 mucosal cancer, 13 submucosal cancer) and 21 non-differentiated tubular adenocarcinoma (12 mucosal cancer, 9 submucosal cancer). The benign gastric lesions included 23 gastric ulcer or gastric ulcer scars, three gastritis, and five gastric adenomas. Small regular patterns were observed; 39% in differentiated adenocarcinoma, 5% in undifferentiated adenocarcinoma, and 19% in benign gastric diseases. Irregular patterns were observed 37%, 52%, and 6%. Lack Divisible structure was observed 18%, 90%, and 10%. Abnormal vessels were observed 26%, 81%, and 16%. Small regular patterns were observed significantly more frequently in differentiated adenocarcinoma than in undifferentiated adenocarcinoma (P < 0.001). Lack of visible structure and Irregular patterns were observed significantly more frequently in undifferentiated adenocarcinoma than in differentiated adenocarcinoma (P < 0.001). In order to spread this useful endoscopy widely easy recognition of abnormality, histological backbone, and further technical developments in hardware and software should be required.
