Abstract
BACKGROUND: Olympus Corporation has developed texture and color enhancement imaging (TXI) as a novel image-enhancing endoscopic technique. AIM: To investigate the effectiveness of TXI in identifying colorectal adenomas using magnifying observation. METHODS: Colorectal adenomas were observed by magnified endoscopy using white light imaging (WLI), TXI, narrow band imaging (NBI), and chromoendoscopy (CE). This study adopted mode 1 of TXI. Adenomas were confirmed by histological examination. TXI visibility was compared with the visibility of WLI, NBI, and CE for tumor margin, and vessel and surface patterns of the Japan NBI expert team (JNET) classification. Three expert endoscopists and three non-expert endoscopists evaluated the visibility scores, which were classified as 1, 2, 3, and 4. RESULTS: < 0.001). CONCLUSION: TXI provided higher visibility than WLI, lower than NBI, and comparable to or higher than CE in the magnified observation of colorectal adenomas.
