• Effect of Aspirin on Biomarkers of Barrett's Esophagus After Successful Eradication of Barrett's Esophagus With Radiofrequency Ablation Rochester, Minn.

  This randomized phase II trial studies the safety of and how well acetylsalicylic acid (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 acetylsalicylic acid can prevent it from returning after it has been successfully treated.
