| [ Summary ] | We assessed magnifying endoscopic findings for diagnosis of the depth of submucosal invasion deeper than 1,000μm in early colorectal carcinoma. With a classification based on the Hakone consensus, type V pit pattern is divived into VI (irregular) and VN (non-structure). In addition, we classified the type VI pit pattern into two groups ; VIA and VIB. Regardless of macroscopic type, the incidence of submucosal invaion deeper than 1,000μm with type VN pit pattern was significantly higher than with non-VN pit patterns. This classification was useful in diagnosing early colorectal carcinoma displaying invasions deeper than 1,000μm, subclassifying the type VI pit pattern. | |
