 We tried to diagnose the depth of invasion of early gastrointestinal cancer by comparing endoscopic ultrasonograms of resected specimens with corresponding histology. The results were as follows; 1) In cases of a depressed type of early cancer, we could diagnose the depth of invasion of cancer by observing the change of an echogram of the submucosal layer (the 3rd layer). 2) In cases of early cancer which invaded to the submucosal layer deeply, an echogram of the submucosal layer was depressed and deviated to an echogram of the muscular layer (the 4th layer). 3) An echo like tumor was visualized under a tumor echo in an elevated type of early cancer and interruptions of an echogram of the submucosal layer were demonstrated in a depressed type of early cancer with fibrosis.
