 This report describes the knacks and pitfalls of colonoscope insertion with a focus on maintaining one axis during insertion. During the detection of superficial colorectal neoplasia, recognition of flat neoplasia should be emphasized and polyps should be disregarded. Following observations in the colonic mucosa should be attended to during the detection of superficial colorectal neoplasia:1. slight redness, 2. disappearance of vascular network, 3. abnormal shine, 4. thickness or irregularity of mucosal folds, and 5. disappearance of the fine network pattern, which is observed through air-volume regulation in the lumen. In addition to small, flat lesions, it is also important to recognize large, superficial lesions such as LST(laterally spreading tumors).
