GERD
Conditions
Brief summary
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.
Detailed description
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. However, the treatment of patients with proven GERD, who have an unsatisfactory response to high doses of PPIs remains a challenge. A number of endoscopic procedures, aimed at improvement of the barrier function of the lower esophageal sphincter (LES), have emerged over the last decade. 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients who report improvement in Quality of Life (QOL) post Stretta procedure as compared to Sham therapy. | 1 year | 6 point GERD Likert Scale will be used to assess the improvement in frequency and severity of GERD symptoms post Stretta procedure & Sham therapy amongst patients. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients who report independence from Proton Pump Inhibitor (PPI) drug post Stretta procedure as compared to Sham therapy. | 1 year | Questionnaire will be provided to each participant to report no further requirement of PPI drug post procedure. |
| Comparison of Increased Lower Esophageal Sphincter pressure among patients post Stretta procedure & Sham Therapy. | 1 year | High Resolution Esophageal Manometry will be performed after the procedure in each patient to compare the LES pressure between the two groups. |
