Clinical Trial 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.

Description:

This study will look at the impact of the brush biopsy results on your doctor's decisions about your future care and treatment. In addition , by recording the results of all your biopsies over 5 years, it may be possible to find out if the brush biopsy, forceps biopsy, or both can predict which patients with heartburn develop Barrett's esophagus, (an abnormality in the esophagus that may lead to cancer), and which patients with Barrett's esophagus develop precancer and cancer. You are being asked to participate in the study because you are receiving an upper endoscopy (a procedure where a tube with a light and camera are inserted in your mouth and down your throat) with forceps and brush biopsies of your esophagus as part of you standard clinical care, and you are at least 18 years old.

Eligibility

Inclusion Criteria:

• Able to read, comprehend and complete the IRB-approved consent form
• Aged 18 or older
• Meet one of the following:
• Patients with heartburn or regurgitation undergoing a screening EGD, who undergo WATS3D sampling and forceps biopsies for suspicion of BE, or
• Patients with known BE with or without dysplasia undergoing a surveillance EGD with WATS3D biopsies and forceps biopsies, or
