 The detection trigger and endoscopic findings with conventional white-light endoscopy of 118 MGC〔minute gastric cancers(5mm or less in diameter)〕were evaluated according to macroscopic and histologic types. The detection trigger was elevation for elevated type MGC, and change of color for depressed type MGC. Endoscopic findings for MGC were : smooth irregular elevation for elevated lesions, reddish well-demarcated irregular depression with surrounding elevation for differentiated type depressed lesions, and small area or depression with discoloration for undifferentiated type depressed lesions. To detect a MGC by conventional white light endoscopy, it is essential to rinse the stomach and pay attention to minute changes of the mucosa in addition to chromoendoscopy.
