| Background: Red dichromatic imaging (RDI) is an image-enhanced endoscopy that can raise the visibility of deep vessels. We previously reported that RDI can predict the depth of esophageal varices (EVs). In this retrospective study, we analyzed whether RDI improves overall survival (OS) and recurrence rate after endoscopic injection sclerotherapy (EIS) compared with white light imaging (WLI). Methods: A total of 205 patients treated by EIS were enrolled, and we finally analyzed 155 patients (RDI group: 70, WLI group: 85) that did not meet the exclusion criteria. Primary endpoints were OS and recurrence rate. Secondary endpoints were treatment time, intravariceal-injection success rate, and the predictor associated with recurrence rate of EVs. Results: There was no difference in OS (P=0.560), but recurrence rate in the RDI group was significantly lower than in the WLI group (P<0.001). The treatment time and the intravariceal-injection success rate were better in the RDI group (p=0.001, and <0.001, respectively). Independent predictors associated with recurrence rate by Cox proportional regression were RDI function and luminal diameter (P=0.003 and 0.007, respectively). Conclusion: RDI did not improve OS but decreased the recurrence rate of EVs and the treatment time of EIS. Independent predictor of recurrence rate was RDI. RDI is thought to be useful in treatment of EVs. |
