Correlation of Magnifying Endoscopy with Histology in the Gastric Mucosal Elevated Lesions

Background/Aims: This is the study to clarify the relation between the mucosal patterns by magnifying endoscopy and the histologic findings in the gastric mucosal elevated lesions. Methods: The objectives were 51 lesions from 48 patients with gastric mucosal elevated lesions. Gastric mucosal elevated lesions have been magnified up to 80 times by using the magnifying endoscope and were obtained tissue. Magnifying mucosal patterns were classified into 6 types (dot, sulciolar, reticular, irregular, destructive and abnormal vessel pattern) and two group (Group A: dot, sulciolar, reticular pattern-preservation of mucosal arrangement, Group B: irregular, destructive, abnormal vessel pattern-destruction of mucosal arrangement). And then we compared the relation between the mucosal patterns and the histologic findings in the gastric mucosal elevated lesions. Results: In magnifying mucosal patterns, dot, sulciolar, reticular, irregular, destructive,and abnormal vessel pattern were 8, 5, 15, 4, 12, 7, respectively. There was significant difference in the rate of severe dysplasia or carcinoma between two groups (Group A: 0% (0/28), Group B: 70% (16/23) (p
