Core Tip
Core tip: Using open biopsy forceps is known to be a useful technique to reduce error rates in colon polyp size measurements, but in practice most endoscopists just measure polyp size by visualization. There is little information about accuracy differences between these two methods. In this study, we showed that the inter-observer difference, diagnostic accuracy, and error range of forceps estimation were better than those of visual estimation in the measurement of the polyp size. We propose that forceps estimation should be considered to measure the colon polyp size before removing the polyp.
