The development of Barrett's esophagus (BE) in patients with gastroesophage
al reflux disease (GERD) is troubling because of its known association with
esophageal cancer. When evaluated clinically, patients with BE have the se
verest form of GERD and require aggressive therapy to control esophageal ac
id exposure. Both hypotension of the lower esophageal sphincter and the ext
ent of esophageal acid exposure are major contributors to severe GERD and i
ts complications. It is hypothesized that better control of acid will impro
ve outcomes for BE patients. While it is clear that therapy (medical or sur
gical) for reflux rarely if ever results in total regression of BE, there a
re some limited data to support improvement in BE with control of reflux. C
urrent medical choices include prokinetic agents, histamine type-2 receptor
antagonists, and proton pump inhibitors. In the future, genetic markers ma
y be used in identifying BE patients at the greatest risk for histologic pr
ogression, and chemoprevention with cyclooxygenase-2 inhibitors may be a th
erapeutic option. This paper will review the rationale for and results of m
edical antireflux therapy in patients with BE. Copyright (C) 2001 S. Karger
