The investigators hypothesize that intensive acid suppression with a long acting high potency proton pump inhibitor (dexlansoprazole) will lead to a greater decrease in levels of inflammatory mediators (compared to conventional PPIs) in the esophagus, which could potentially lead to decreased recurrence of intestinal metaplasia following endoscopic ablation.

Primary Outcome Measures:
  • Inflammation reduction [ Time Frame: 6-24 months ] [ Designated as safety issue: No ]
    We hypothesize that intensive acid suppression will reduce inflammation associated markers in the esophagus with a potential reduction in the rate of recurrent BE following ablation.

Arms Assigned Interventions
Active Comparator: dexlansoprazole
patients will be treated with dexlansoprazole 60 mg/day for 6 months
Drug: dexlansoprazole
Other Name: Dexilant

Ages Eligible for Study:   18 Years to 90 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Patients who have undergone ablation for BE and HGD or LGD with PDT/Radiofrequency ablation and endoscopic mucosal resection who have no endoscopic and histologic evidence of specialized intestinal metaplasia on biopsies from the esophagus on two successive endoscopies post ablation will be offered enrollment in the study.

Inclusion criteria:

  1. Absence of intestinal metaplasia on endoscopy (under Narrow Band Imaging) and on histology (from biopsies taken from gastroesophageal junction and distal esophagus) on two successive surveillance endoscopies.
  2. Able to consent to study
  3. Males and females age 18-90
  4. Life expectancy of 5 years or greater.

Exclusion criteria:

  1. Pregnancy
  2. Inability to consent for the procedure
  3. Anticoagulation therapy precluding performance of ambulatory pH monitoring and/or biopsies
  4. Intolerance to proton pump inhibitors
  5. Elevation in AST, ALT, Bilirubin or alkaline phosphatase more than five times the upper limit of normal.
