  • Look Inside

 Although reflux esophagitis is a widespread disease, there have been few reports in which endoscopic findings with iodine and toluidine blue staining have been described in detail. In this paper, we reveal the usefulness of iodine staining for identification of regenerative epithelium and previous esophagitis, and differentiation of benign and malignant erosions or ulcers. We also demonstrated the beneficial role of toluidine blue staining for estimatlon of the depth of inflammation and differentiation of erosion and regeneration. Chromoendoscopic findings of reflux esophagitis using iodine together with toluidine blue are presented as well. Furthermore, we present our system for showing the stage of reflux esophagitis according to the stage of gastric ulcers as defined by Sakita and Miwa. We discuss the problems for the clinical application of this system. We also discuss the criteria for description of reflux esophagitis.
