BACKGROUND/AIMS: Dual red imaging (DRI) is a new, image-enhanced endoscopy technique. There are few reports about the usefulness of DRI during gastric endoscopic submucosal dissection (ESD). We aimed to examine the usefulness of DRI in endoscopic hemostasis during gastric ESD.
METHODS
We enrolled a total of 20 consecutive patients who underwent gastric ESD. Five endoscopists compared DRI with white light imaging (WLI) for the visibility of blood vessels and bleeding points while performing endoscopic hemostasis.
RESULTS
The visibility of blood vessels was increased in 56% (19/34) of the cases, and the visibility of bleeding points was improved in 55% (11/20) of the cases with the use of DRI compared with the use of WLI.
CONCLUSION
DRI improved the visibility of blood vessels and bleeding points in cases with oozing bleeding, blood pooling around the bleeding points, and multiple bleeding points.
背景/目的：双红成像（DRI）是一种新型的图像增强内镜技术。关于DRI在胃内镜黏膜下剥离术（ESD）中的应用价值的报道较少。我们旨在探讨DRI在胃ESD内镜止血中的应用价值。
方法
我们共纳入了20例连续接受胃ESD的患者。5名内镜医师在进行内镜止血时，比较了DRI与白光成像（WLI）对血管和出血点的可视性。
结果
与使用WLI相比，使用DRI时，56%（19/34）的病例血管可视性增加，55%（11/20）的病例出血点可视性改善。
结论
DRI提高了渗血、出血点周围血液积聚和多个出血点病例中血管和出血点的可视性。
