We wish to determine whether biopsies obtained with the technique of fluorescence-aided confocal endomicroscopy will detect more patients with specialized columnar epithelium than random biopsies among patients with Barrett's esophagus who are being monitored with endoscopy.

Condition Intervention Phase
Barrett's Esophagus
Other: Fluorescence-aided confocal endomicroscopy guided biopsy.
Other: Random four-quadrant biopsies.
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
