Abstract

BACKGROUND/AIMS: Visualization of palisade vessels (PVs) in Barrett's esophagus is crucial for proper assessment. This study aimed to determine whether red dichromatic imaging (RDI) improves PV visibility compared with white-light imaging (WLI) and narrow-band imaging (NBI).

METHODS

Five expert and trainee endoscopists evaluated the PV visibility in Barrett's esophagus using WLI, NBI, and RDI on 66 images from 22 patients. Visibility was rated on a 4-point scale: 4, excellent; 3, good; 2, fair; and 1, poor. The color difference between the most recognizable PV spots and surrounding areas with undetectable blood vessels was also analyzed.

RESULTS

Mean visibility scores were 2.6±0.7, 2.3±0.6, and 3.4±0.4 for WLI, NBI, and RDI, respectively. The RDI scores were significantly higher than the WLI (p<0.001) and NBI (p<0.001) scores. These differences were recognized by trainees and expert endoscopists. Color differences in PVs were 7.74±4.96 (WLI), 10.43±5.09 (NBI), and 15.1±6.54 (RDI). The difference in RDI was significantly higher than that in WLI (p<0.001) and NBI (p=0.006).

CONCLUSIONS

RDI significantly improved PV visibility compared to WLI and NBI based on objective and subjective measures.

摘要

背景/目的：巴雷特食管中栅栏状血管（PVs）的可视化对于准确评估至关重要。本研究旨在确定与白光成像（WLI）和窄带成像（NBI）相比，红色双色成像（RDI）是否能提高PVs的可视性。

方法

五名专家和实习内镜医师使用WLI、NBI和RDI对来自22名患者的66张图像评估巴雷特食管中PVs的可视性。可视性按4分制评分：4分，优秀；3分，良好；2分，一般；1分，差。还分析了最易识别的PVs斑点与周围无血管区域之间的颜色差异。

结果

WLI、NBI和RDI的平均可视性评分分别为2.6±0.7、2.3±0.6和3.4±0.4。RDI评分显著高于WLI（p<0.001）和NBI（p<0.001）评分。实习医师和专家内镜医师均认识到了这些差异。PVs的颜色差异分别为7.74±4.96（WLI）、10.43±5.09（NBI）和15.1±6.54（RDI）。RDI的差异显著高于WLI（p<0.001）和NBI（p=0.006）。
