The Barrett's ulcer is found in 24% cases of Barrett's esophagus as a precancerous lesion of the esophageal adenocarcinoma. We report a case of Barrett's ulcer with complete occlusion due to reflux esophagitis. An 82-year-old woman had a chief complaint of vomiting. An obstructing lesion was detected in UGI in the lower esophagus and injection of contrast media did not reveal debouchement to the anal side. GIF revealed an occulusion at 30 cm from the incisor line. Chest CT revealed thickening of the well of the lower esophagus, and no high-intensity signal was observed on the MRI diffusion emphasis image. Because stenting was difficult, we performed esophagectomy. Histopathological image of the narrow segment revealed ulceration, and the anal mucosal surface of the occlusion site was covered by specialized columnar epithelium.
