Reading capsule endoscopy (CE) is time-consuming. The Express View (EV) (IntroMedic, Seoul, Korea) software was designed to shorten CE video reading. Our primary aim was to evaluate the diagnostic accuracy of EV in detecting significant small-bowel (SB) lesions. We also compared the reading times with EV mode and standard reading (SR). METHODS: 126 patients with suspected SB bleeding and/or suspected neoplasia were prospectively enrolled and underwent SB CE (MiroCam®1200, IntroMedic, Seoul, Korea). CE evaluation was performed in standard and EV mode. In case of discrepancies between SR and EV readings, a consensus was reached after reviewing the video segments and the findings were re-classified. RESULTS: The completion rate of SB CE in our cohort was 86.5% and no retention occurred. The per-patient analysis of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EV compared to SR were 86%, 86%, 90%, 81%, and 86%, respectively, before consensus. After consensus, they increased to 97%, 100%, 100%, 96%, and 98%, respectively. The median reading time with SR and EV was 71 min (range 26−340) and 13 min (range 3−85), respectively (p < 0.001). CONCLUSIONS: The new-generation EV shows high diagnostic accuracy and significantly reduces CE reading times.
阅读胶囊内镜（CE）耗时较长。快速视图（EV）（韩国首尔IntroMedic公司）软件旨在缩短CE视频的阅读时间。我们的主要目的是评估EV在检测小肠（SB）重大病变方面的诊断准确性。我们还比较了EV模式和标准阅读（SR）的阅读时间。
前瞻性纳入126例疑似SB出血和/或疑似肿瘤的患者，并进行SB CE检查（韩国首尔IntroMedic公司的MiroCam®1200）。以标准模式和EV模式进行CE评估。如果SR和EV阅读结果存在差异，则在查看视频片段后达成共识，并对结果重新分类。
我们队列中SB CE的完成率为86.5%，未发生滞留情况。在达成共识之前，与SR相比，EV的患者个体敏感性、特异性、阳性预测值、阴性预测值和诊断准确性分析分别为86%、86%、90%、81%和86%。达成共识后，它们分别提高到97%、100%、100%、96%和98%。SR和EV的中位阅读时间分别为71分钟（范围26 - 340）和13分钟（范围3 - 85）（p < 0.001）。
新一代EV显示出较高的诊断准确性，并显著缩短了CE阅读时间。
