Barrett's surveillance identifies patients with early esophageal adenocarcinoma.

Background: Barrett's surveillance for dysplasia is recommended, but few studies have documented the benefit of endoscopic surveillance for dysplasia or cancer.

Objectives: Using a retrospective study design, we aim to demonstrate the impact of a Barrett's surveillance program on the stage of esophageal adenocarcinoma and identify factors for progression of metaplasia to cancer.

Subjects: The Institutional Review Board at Veterans Affairs Connecticut Healthcare approved the study.
