The WATS3D (Wide Area Transepithelial Sample Biopsy with 3-Dimensional Computer-Assisted Analysis) U.S. Registry

Brief description of study

The purpose of this study is to create a registry to learn more about two methods of taking small tissue samples from your esophagus. Two methods of collecting tissue samples from the esophagus are: 1) Using forceps that take biopsies from your esophagus, and 2) Using a brush that also takes biopsies from your esophagus. By recording the results of all of your biopsies over many 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, and which patients with Barrett’s esophagus develop precancer and cancer. The data from your biopsies will be used to learn more about the best way to diagnose esophageal disease.
