Background/Aims: Dual red imaging (DRI) is a new, image-enhanced endoscopy technique. There are few reports about the usefulnessof DRI during gastric endoscopic submucosal dissection (ESD). We aimed to examine the usefulness of DRI in endoscopic hemostasisduring gastric ESD. Methods: We enrolled a total of 20 consecutive patients who underwent gastric ESD. Five endoscopists compared DRI with white lightimaging (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 in55% (11/20) of the cases with the use of DRI compared with the use of WLI. Conclusions: DRI improved the visibility of blood vessels and bleeding points in cases with oozing bleeding, blood pooling around thebleeding points, and multiple bleeding points.
