| [ Summary ] | Twelve endoscopists independently evaluated twelve colonic neoplasms, using only magnified NBI or FICE images. Endoscopic findings and speculative histopathological diagnoses were required for development of interobserver agreement and diagnostic accuracy. In elevated type of lesions, observer agreement concerning endoscopic findings was high in relation to surface and vascular patterns, but low in relation to histopathological diagnostic speculation. In superficial type of lesions, interobserver agreement of endoscopic findings was relatively high in relation to surface patterns. Only vascular interruptions were observed in vascular patterns. There is a high probability of speculative histopathological diagnostic ability with this technique. Findings indicating vascular interruption contributed to diagnoses of cancer. |
