Abstract
This article reviews the epidemiology of Barrett's esophagus (BE) and current evidence for or against screening for BE to provide insight into the screening process. Data demonstrate that multiple criteria of a successful screening program remain unfulfilled or unproven in endoscopic screening for BE. The operating characteristics of the test are poorly described, and inadequate risk stratification limits the effectiveness and cost-effectiveness of the approach. We suggest modifications to BE screening practices that may have the potential to improve outcomes for patients with BE.
