Core Tip
Core tip: In this study, we established an endoscopic lesion measurement system (ELMS) to measure polyp size during endoscopy. We measured 192 polyps from 162 patients and found that the accuracy of visual estimation for colonic polyp size is low. The accuracy of estimating polyp size was distinctly increased when measured by disposable graduated biopsy forceps and ELMS. In particular, the accuracy of estimation by ELMS was higher than the clinician’s estimation and DGBF for polyps > 1 cm.
