Confocal Microscopy in Barrett's Esophagus

This retrospective chart review will be done to evaluate the use of confocal microscopy
imaging in patients who were seen at Mayo Clinic for clinically indicated endoscopic
surveillance and biopsies of BE.

Endoscopy reports and pathology results will be reviewed from 100 patients who have
undergone endoscopy. These results will be correlated with images obtained with confocal
microscopy at the time of the endoscopy. There will be no patient contact.

Inclusion Criteria:
