Abstract

To minimize the risk for interval cancer after colonoscopy, we need to improve detection of small (<10 mm) and minute (<5 mm) flat-type neoplasias and inconspicuous laterally spreading tumors, and we aim to analyze neoplasias for risk of superficial or invasive cancer. Currently, endoscopic en bloc resection yields poor curative resection rates outside East Asia, mainly owing to non-exclusion of deep sm2–3 invasive colorectal cancer lesions. Therefore, we focus on endoscopic distinction of benign lesions versus malignant neoplasias, and of superficial versus deep submucosa-invasive (sm2–3) early colorectal cancer; both distinctions are required to determine indications for endoscopic en bloc resection or surgery.
