NCT00587652

Brief Summary

This study is being done to: Determine if a temporary dye applied to the esophagus identifies areas of dysplasia (pre-cancer). Determine if certain dye patterns indicate specific grades of dysplasia. Determine if overall endoscopy costs can be reduced with this dye technique. Determine if the dye could allow fewer biopsies to be obtained in the future.
