Validity of conventional endoscopy using “non-extension sign” for optical diagnosis of colorectal deep submucosal invasive cancer

Background and study aims The non-extension sign relates to a localized increase in thickness and rigidity due to deep submucosal invasive (SM-d: depth of 1000 μm or more) cancer.
