To evaluate the efficacy of endoscopic findings after submucosal 20%glucose infectionin diagnosing the depth of invasion of colorectal cancer, 77 cases were analyzed, and thedepth of invasion of the lesion lifted after injection was defined as M'or 5M1', and that ofnot lifted was SM2'and more. The depth of invasion of 62 cases of 681ifted lesions wereSM1'and less(91.2%). The endoscopic features of 4 cases of the other(6)lesions weresubpedunculated polyps. The depth of invasion of g cases of g not lifted lesions were SM2'and more (100%). Sensitivity was 91.2%, specificity 100%, and overall accuracy was 92.2%.Therefore it was concluded that endoscopic findings after submucosal injectionwas practical and useful method far diagnosing the depth of invasion.
