Abstract

BACKGROUND AND AIMS: The reported progression rate from low-grade dysplasia (LGD) in Barrett's esophagus (BE) to high-grade dysplasia (HGD) or esophageal adenocarcinoma (EAC) ranges from 0.4% to 13.4% per year. We hypothesize that some of the reported progression rates may be overestimated due to prevalent HGD or EAC, which was not identified during endoscopic assessments performed in the community. The aim is to determine the proportion of prevalent HGD or EAC detected by Barrett's esophagus referral units (BERU) in patients referred from the community with a recent diagnosis of LGD. METHODS: All patients referred from the community to 6 BERU with a diagnosis of BE with LGD were identified...
