Diagnosis and endoscopic treatment of esophago-bronchial fistula due to gastric heterotopy

Figure 1 Barium follow through of the esophagus revealing the esophago-bronchial fistula.

Figure 2 Endoscopic view of the proximal opening (open and closed) of the esophago-bronchial fistula caused by heterotopic gastric mucosa. A: Closed; B: Open.

Figure 3 Heterotopic gastric mucosa in middle esophagus. A: Arrows denote the transition between the columnar foveolar epithelium and the esophageal stratified squamous epithelium (H&E, × 40); B: Columnar epithelium merges with stratified squamous epithelium. At the lamina propria cardiac and fundic-type glands are evident (H&E, × 200).
