Background and Rationale:
Gastroesophageal reflux disease is affecting 1 in 3 US adults with half experiencing daily symptoms. Per recent data, more than 50% continue to experience daily symptoms despite taking medical therapy and not eligible for surgery. In that small fraction of patients who are eligible for surgery, more than 70% resume taking a medicine for their reflux disease. GERD is common among the US veterans and currently there is a lack of minimally invasive endoscopic therapies for management of GERD. This study will investigate performance of minimally invasive, endoscopic therapy using antireflux mucosal ablation (hybrid argon plasma coagulation) that has been used in other areas of GI tract with efficacy and safety for management of chronic GERD among the US veterans.
Objective:
The aim of this study is to assess the safety and effectiveness of antireflux mucosal ablation or ARAT (intervention group) in patients with chronic gastroesophageal reflux disease (GERD) symptoms (typical symptoms of GERD, i.e. heartburn or acid reflux/regurgitation at least twice a week) for the last 6 months and objective evidence of reflux disease (positive ambulatory pH study off PPI for 5-7 days) compared to sham procedure (control group).
Patients with chronic GERD symptoms (at least 1 typical symptom of GERD, i.e. heartburn or acid reflux/regurgitation at least twice a week) for last 6 months and
Objective evidence of reflux disease (positive ambulatory pH study)

Able to undergo upper endoscopy as evidenced by completion of pre-endoscopy standard of care checklist.
Patients unable to or unwilling to participate or consent
Age <18 years or >80 years
Allergic or intolerant to PPI medications
Large hiatal hernia > 3 cm and Hill grade IV
