BACKGROUND: Radiofrequency (RF) energy treatment is increasingly offered before invasive surgical procedures for selected patients with gastroesophageal reflux disease (GERD). METHODS: Thirty-two patients undergoing the Stretta procedure were prospectively evaluated with upper endoscopy, manometry, 24-hour pH testing, SF-36 surveys, and GERD-specific questionnaires (GERD HRQL).
RESULTS: Significant clinical improvement was observed in 91% of patients (29/32). Mean heartburn and GERD HRQL scores decreased (p = 0.001 and p = 0.003, respectively), and physical SF-36 increased (p = 0.05). At a minimum follow-up of 12 months, median esophageal acid exposure decreased (p = 0.79) and was normalized in eight patients. Median lower esophageal sphincter (LES) pressure was unchanged. Esophagitis healed in six of eight patients, but two patients with nonerosive disease developed asymptomatic grade A esophagitis during follow-up. At 12 months, 56% of patients were off proton pump inhibits. Morbidity was minimal.
CONCLUSIONS: RF delivery to LES is safe and significantly improves symptoms and quality of life in selected GERD patients.
