This randomized phase II trial studies the safety of and how well aspirin works in preventing
Barrett's esophagus from returning after it has been successfully eliminated by
radiofrequency ablation. Studying samples of tissue from patients with Barrett's esophagus
for the levels of a specific protein that is linked to developing Barrett's esophagus may
help doctors learn whether aspirin can prevent it from returning after it has been
successfully treated.
