 NBIME(narrow-band imaging magnified endoscopy), one of the image-enhanced endoscopy modes, has been reported as a useful tool for detecting and diagnosing Barrett's esophagus and adenocarcinoma. It is primarily important not to miss redness or rough surface in conventional white light endoscopy for detecting superficial Barrett's adenocarcinoma. In NBIME, the half-zoom mode should be recommended for observing the whole of Barrett's esophageal surface and in order to find abnormal mucosal pattern surrounded by a demarcation line. Then, by increasing the magnification power, irregularities of microvessels should be evaluated if you find a demarcated abnormal mucosal pattern. NBIME can be a very useful diagnostic tool when estimating tumor extent before endoscopic resection. We describe two cases of Barrett's adenocarcinoma at an early stage which NBIME allowed us to detect and diagnose the tumor extent exactly. Clinical utility of NBIME for Barrett's adenocarcinoma is discussed in this manuscript.
