Abstract

Barrett's esophagus is defined as the replacement of normal squamous epithelium of distal esophagus with metaplastic columnar epithelium. It is a well known risk factor of esophageal adenocarcinoma. If high grade dysplasia or early stage esophageal cancer develops in a patient with Barrett's esophagus, esophagectomy shoud be performed. However, operative procedures have various complications and the patients may suffer resulting in poor quality of life. Therefore, if the cancer is detected at an early stage such as superficial mucosal lesion, it is possible to resect the tumor with the use of endoscopic technique. Furthermore, endoscopic mucosal resection (EMR) also can be performed for the patients with mucosal or submucosal cancer who can not receive esophagectomy due to old age or poor general condition. We experienced a case of esophageal adenocarcinoma from Barrett's esophagus which had been successfully resected endoscopically.
