UNASSIGNED: Background and study aims   Colonoscopies can predict long-term prognoses in @entity1 with @entity31 ( @entity31 ). Recently, a new imaging technology has been developed that uses 3 types of illumination with center wavelengths of 540nm, 600nm, and 630nm. The use of both the 600-nm and 630-nm lights (Dual red imaging; DRI) is critical for identifying blood vessels in deeper tissue. The aim of this study was to evaluate the usefulness of DRI for assessing the severity of @entity32 in @entity1 with @entity31 . @entity1 and methods   A total of 43 @entity31 @entity1 were retrospectively enrolled to evaluate the endoscopic severity of 112 colon segments, and Mayo endoscopic scores, DRI scores and the severity of @entity32 on a visual analogue scale (VAS) were compared. The Mayo endoscopic scores, DRI scores, and histologic scores were evaluated, and the interobserver agreement on DRI scores among 5 investigators was also assessed. The usefulness of DRI scores for predicting prognoses was also assessed in @entity1 with clinical remission. Results   The DRI scores were closely correlated with the VAS for the severity of @entity32 (r=0.96) and the histologic scores (r=0.72-0.8). The DRI scores had a higher rate of interobserver agreement (k values=0.63-0.88) than the Mayo endoscopic scores (k values=0.44-0.59). Inter-observer agreement between 4 non-experts was also excellent (mean k value=0.76, range 0.63-0.82). The expected time until recurrence was significantly longer in @entity1 with lower DRI scores (P<0.01). Conclusion   DRI can be used in @entity1 with mild to moderate endoscopic severity because it targets the deep vascular pattern. The prognosis of @entity31 can be predicted by assessing deep vessels using DRI.
