Barrett's esophagus is a pre-malignant condition associated with adenocarcinoma of the lower esophagus, and is found in 10-15% of patients with Gastroesophageal Reflux Disease (GERD). In prospective studies of patients undergoing endoscopy for reflux symptoms, the prevalence of long segments of Barrett's Esophagus (3cm or greater) is reported to be 3% and that of short segment Barrett's Esophagus (less than 3cm), to be approximately 7-8%. Early diagnosis with surveillance is considered the optimal approach in patients with Barrett's, given the poor survival of advanced adenocarcinoma of the esophagus. However, classic symptoms of GERD may be diminished in some patients with Barrett's esophagus, possibly leading to a lower incidence of endoscopy with early diagnosis.
