| The advent of Texture and Color Enhancement Imaging (TXI) technology represents a significant innovation in endoscopic imaging. As no previous reports have applied TXI to EVs, this study assesses the effectiveness of TXI in visibility EVs compared to conventional methods. 130 EV patients in our department were enrolled between January 2023 and February 2024. EVs and RCsings were observed using white light imaging (WLI), TXI, narrow band imaging (NBI), and Red Dichromatic Imaging (RDI) modes 1-3. Seven expert endoscopists, including hepatologists, evaluated the visibility of each modality on a five-point scale (-2 to +2) compared to WLI. The color differences (ΔE) were also calculated for each objective assessment. The visibility score showed positive ratings for TXI and RDI-3, with TXI scoring significantly higher than RDI-3 (1.7, 1.0, respectively, p<0. 01). TXI scored highly in the RCsings. TXI had the highest ΔE for EVs (24.8) and RCS (27.3). Sub-analysis by Formation and Location showed higher scores and ΔE E for TXI, and all endoscopists rated it higher in inter-rater reliability. Based on the results, TXI and WLI were compared in a pilot study in 10 patients who underwent EVL. TXI scored 1.3 and had a higher ΔE (TXI 21.9 vs WLI 9.1, p=0.01). TXI significantly outperforms other images in visualizing EVs, paving the way for improved diagnostic accuracy and advancing therapeutic approaches. |
