Role of digital chromoendoscopy in detecting minimal change esophageal reflux disease

Figure 1 Images from magnifying non-sequential NBI show increased number and dilated and tortuous of intrapapillary capillary loops.

Figure 2 Triangular lesion (arrow). A: Conventional white light endoscopy; B: FICE station 0 (RGB wavelength of 540, 415 and 415 nm); C: FICE station 4 (RGB wavelength of 560, 500 and 475 nm).

Figure 3 Images from magnifying FICE of × 100 show increased number and dilated and tortuous of intrapapillary capillary loops (IPCL). A: Conventional white light endoscopy; B: FICE station 0 (RGB wavelength of 540, 415 and 415 nm); C: FICE station 4 (RGB wavelength of 560, 500 and 475 nm).

Figure 4 Images from i-SCAN. A: HD+: A mucosal break is not clearly visible; B: i-SCAN can better depict the mucosal break; C: Lugol’s stain reveals a larger extent of the mucosal break which can help upgrade the degree of esophagitis according to Los Angeles classification.
