Additive Value of Wide-Area Transepithelial Sampling (WATS3D) in Detection of Recurrence of Intestinal Metaplasia Following Endoscopic Eradication Therapy (EET) for Barrett's Esophagus-Related Neoplasia
Esophageal cancer is a deadly disease that is becoming increasingly common in the United States. Barrett's esophagus (BE) is a pre-cancerous state that can develop into esophageal cancer, but is highly treatable. Progression of BE to esophageal cancer is still common due to missed diagnosis of Barrett's esophagus recurrence following treatment. Wide-Area Trans-Epithelial Sampling (WATS-3D) is a new technology that uses brush sampling to examine larger areas of the esophagus as compared to conventional biopsies. Preliminary studies show improved detection of cancerous changes in Barrett's esophagus surveillance. The investigators hope to see if the addition of WATS-3D increases the rate of detection of recurrent BE following treatment, which is of the utmost importance since it would allow for earlier re-treatment of disease and ultimately allow for prevention of progression to esophageal cancer.
• All patients aged 18+ diagnosed with Barrett's esophagus with confirmed histologic dysplasia or intra-mucosal cancer undergoing surveillance after EET
• Patients who have achieved CE-IM on at least one surveillance endoscopy following EET
• All subjects must have given signed, informed consent prior to registration in the study
