Details and patient eligibility

About

The hypothesis is that the addition of a transparent cap to the end of the endoscope will increase the detection and diagnostic yield of visible lesions in Barrett's esophagus. Thus, the goal of this tandem design trial is to compare the diagnostic yield (DY) of cap assisted endoscopy with that of conventional endoscopy using high definition-white light endoscopy (HD-WLE) and narrow band imaging (NBI) in patients with Barrett's esophagus.
