Professor Yoji Takeuchi, Osaka International Cancer Institute This was an elevated-type, deeply invasive carcinoma in the lower rectum. In the distant view under non-magnifying observation (WLI, TXI, NBI, and chromoendoscopy), entire images were bright and in focus due to BAI-MAC, which enabled comprehension of the lesion’s irregular morphology, leading to the suspicion that the lesion represented an invasive carcinoma. In TXI observation, the surface structures were further enhanced after indigo carmine spraying. Even when the magnification function was not used, rough surface structures and vascular architecture could be recognized in close-up NBI observation, enabling targeting of areas where further detailed examination using magnifying observation would be necessary. Focus adjustment — which, in conventional magnifying observation had to be precisely adjusted in minute increments — was switchable at the touch of the Near Focus button. EDOF made it easy to obtain clear, in-focus images, which should support the popularization of magnifying endoscopy. Scope: CF-EZ1500DI Case: Early rectal cancer, SM deep invasion carcinoma Organ: Lower rectum Patient information: F, 54 Medical history: Nothing worth noting
