This study aimed to evaluate the efficacy of red dichromatic imaging (RDI) in improving the visibility of bleeding during gastric endoscopic submucosal dissection (ESD). The results showed that RDI significantly improved the visibility score and color difference of bleeding spot compared to white light imaging (WLI) during gastric ESD. Further analysis revealed that the submergence of bleeding points was independently associated with the superiority of RDI. Therefore, RDI can effectively enhance the visibility of bleeding during gastric ESD.
Bleeding frequently occurs during gastric endoscopic submucosal dissection (ESD) and bleeding points are sometimes difficult to detect. Red dichromatic imaging (RDI) was recently developed to improve the visibility of bleeding. Our study aimed at examining the efficacy of RDI in improving the visibility of bleeding during gastric ESD. We retrospectively evaluated the visibility score and color difference of bleeding spot during gastric ESD during September 2020-January 2021. The visibility score was evaluated as four numeric values by operators, and the color difference between the bleeding spot and surroundings was evaluated using RDI and white light imaging (WLI). A further analysis to evaluate bleeding characteristics was performed to evaluate the possible beneficial effects of RDI. Twenty patients with a total of 85 bleedings were analyzed. The mean visibility score in RDI was significantly higher than that in WLI (3.69 +/- 0.60 vs 3.20 +/- 0.84, p < 0.01). The color difference with RDI was also significantly higher than that with WLI (19.51 +/- 15.18 vs 14.80 +/- 7.41, p < 0.01). Furthermore, in the bleedings with a higher visibility score in RDI, the color difference in RDI was significantly higher than that in WLI (23.99 +/- 19.29 vs 14.33 +/- 7.08, p < 0.01). The multivariate analysis of visibility scores revealed that submergence of bleeding points was independently associated with the superiority of RDI (odds ratio 10.35, 95% confidence interval: 2.76-38.81, p < 0.01). Our study demonstrates that RDI can improve the visibility of bleeding during gastric ESD.
