Abstract
A 30-year-old white man with established Barrett's esophagus (BE) and continued symptoms of chronic severe heartburn, persistent cough, throat irritation, and asthma was referred for surveillance EGD at the VA Boston Healthcare System. During retraction of the endoscope, a pink circular lesion (A) was observed under white light endoscopy in the upper esophagus (spanning 20-22 cm from the incisors). Three-dimensional endoscopic optical coherence tomography (OCT) images were obtained of the region under direct visualization with white light by passing the probe through the standard accessory channel.
