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.

利用红色二色成像改善Barrett食管内栅栏血管的可见性：日本的一项回顾性横断面研究。

背景/目的：Barrett食管栅栏血管（pv）的可视化对正确评估至关重要。本研究旨在确定与白光成像（WLI）和窄带成像（NBI）相比，红二色成像（RDI）是否能提高PV的可见性。方法：5名专家和见习内窥镜医师使用WLI、NBI和RDI对22例患者的66张图像进行Barrett食管PV可见性评估。能见度评分为4分：4分，优秀；3,好;2、公平;而我，可怜。最容易识别的PV点与周围未检测到血管的区域之间的色差也进行了分析。结果：WLI、NBI和RDI的平均能见度评分分别为2.6±0.7、2.3±0.6和3.4±0.4。结论：基于客观和主观测量，与WLI和NBI相比，RDI显著提高了PV可视性。
