Core Tip
Core tip: This present study was designed to evaluate the depth of invasion of small, early colorectal cancers using conventional endoscopic features. This study exhibited that invasive pit patterns were a more accurate finding than morphological features or non- lifting signs to discriminate small, deep submucosa (SM) cancers from superficial SM cancers by a white light, standard colonoscopy. However, it also showed that conventional endoscopic findings, such as morphological features, non-lifting sign, and invasive pit patterns are insufficient to discriminate deep SM cancers to determine therapeutic strategy under white light standard colonoscopy.
