Brief Summary

The purpose of this study is to create a registry (collect data and keep it in a research database) to learn more about two methods of taking small tissue samples from your esophagus (the esophagus is the tube that carries food and liquid from your mouth to your stomach). The two methods of sampling are: 1) Using forceps that take biopsies (small tissue samples) from your esophagus, and 2) Using a brush that also takes biopsies from your esophagus.

Eligibility Criteria

Exclusion Criteria: * Pregnancy at time of endoscopy * Unresolved drug or alcohol dependency that will limit ability to comprehend or follow instructions related to informed consent, post-treatment instructions or follow-up guidelines * Medical condition that will likely prohibit completion of a 5 year study
