Abstract
The present recommended strategy for detection of dysplasia and cancer in Barrett's esophagus is by randomly carrying out four quadrant biopsies every 2 cm. This approach is however prone to sampling error. Narrow band imaging has been routinely available for clinical use for more than half a decade now. This review will focus on the available data to date on the role of narrow band imaging in the detection and characterization of specialized intestinal metaplasia, high grade dysplasia and intramucosal cancer in Barrett's esophagus.
