Radical excision of Barrett's esophagus and complete recovery of normal squamous epithelium

Figure 2 Barrett’s adenocarcinoma with high-grade dysplasia and severe stenosis. A: Barrett’s adenocarcinoma (white arrows) with high-grade dysplasia and severe stenosis of the lower esophagus; B: On days 5, 8, 12, 15 and 20 after endoscopic submucosal dissection, steroid application and balloon dilatation were performed to prevent stenosis; C: The base of the artificial ulcer on day 12 after surgery. Regenerating squamous epithelium can be seen from the resection margins of the proximal side indicated by the dotted arrows; D: On day 60, the base of the artificial ulcer is thoroughly covered with regenerating squamous epithelium (black arrows). No recurrence has been observed for 5 years.
