case_images: RFA catheter deflated inside the esophagus after the first ablating session. On the right is clearly visible the greyish ablated mucosa.

case_images: The RFA procedure started moving from distally to proximally, and the balloon was progressively repositioned allowing a very small overlap with the previous treated zone (Figure 1).
case_images: CLE image and histologic aspect (trasversal section) of the proximal treated esophageal area. Normal squamous esophagus showing individual epithelial cells and intrapapillary capillary loops.

case_images: The capillary loops within the papillae were visible due to the high contrast of the fluorescein within the vascular structures, surrounded by normal epithelial cells (Figures 2 and 3).
case_images: CLE image of the treated esophageal area, middle portion. Normal squamous esophagus showing individual epithelial cells and intrapapillary capillary loops.

case_images: The capillary loops within the papillae were visible due to the high contrast of the fluorescein within the vascular structures, surrounded by normal epithelial cells (Figures 2 and 3).
case_images: CLE image and histologic aspect (trasversal section) of the untreated esophageal zone: columnar lined epithelium with presence of focal mucin goblet cells (arrows), pathognomonic of gastric type mucosae with focal intestinal metaplasia.

case_images: In that case, the CLE revealed regular-shape subepithelial capillaries underneath a columnar-lined epithelium with presence of focal dark mucin goblet cells in the upper parts of the mucosal layer (Figure 4).
