Histopathological confirmation of similar intramucosal distribution of fluorescein in both intravenous administration and local mucosal application for probe-based confocal laser endomicroscopy of the normal stomach

Figure 1 Local mucosal application of fluorescein for probe-based confocal laser endomicroscopy. A: Preparation for local mucosal application of fluorescein. 0.1 mL of 10% fluorescein solution is applied to the dye-spraying tube so that the dye alternates with air; B: Endoscopy findings immediately after local mucosal application of fluorescein onto the gastric body mucosa.
