Endoscopic hemostasis for spurting duodenal bleeding using dual red imaging

Abstract

Endoscopic hemostasis for spurting gastrointestinal bleeding is sometimes difficult to achieve, because a precise bleeding point is often indistinguishable due to persistent hemorrhage. Dual red imaging (DRI) is a novel image enhancement technology that uses 3 wavelengths: 540 nm, 600 nm, and 630 nm. It was reported that DRI improves the visibility of deeper submucosal blood vessels and the bleeding point because 600 nm and 630 nm lights can penetrate deep into the tissue.^1-4 We describe an educational case of spurting duodenal bleeding in which DRI was used to achieve endoscopic hemostasis
