STRETTA ,Radio Frequency Ablation (RFA) v/s Sham Therapy for the Treatment of Refractory GERD

Gastro-esophageal reflux disease (GERD) is a chronic disorder with significant impact on the quality of life of patients. It may also lead to several complications like peptic strictures, ulcerations, Barrett \'s disease and subsequently adenocarcinoma of the esophagus. Proton pump inhibitors (PPIs) are the mainstay of GERD treatment, with up to 90 % of patients with reflux disease becoming asymptomatic while taking PPIs. Several studies have demonstrated that RF delivery at the gastro-esophageal junction(GEJ), also called the Stretta procedure, induces symptom relief and decreases need of PPI intake in GERD. The investigators propose to perform a sham-controlled randomized study to evaluate the influence of the Stretta procedure on symptoms and esophageal acid exposure in patients of refractory GERD.
