title: Radiofrequency energy delivery to the lower esophageal sphincter (Stretta procedure) in patients with recurrent reflux after antireflux surgery: can surgery be avoided?
abstract: BACKGROUND
  Recurrent reflux following antireflux surgery (ARS) can be difficult to manage, especially in patients who also fail medical management. In these patients, redo ARS remains the only treatment option. Endoscopic radiofrequency energy delivery to the lower esophageal sphincter (the Stretta procedure; Stretta, Curon, Sunnyvale, CA) has been shown to significantly decreased symptom scores and improve quality of life in patients with gastroesophageal reflux disease (GERD). The aim of this study was to evaluate the use of the Stretta procedure in treating patients with recurrent reflux after fundoplication.
  
  
  METHODS
  Between March 2002 and December 2003, eight patients with recurrent reflux following ARS underwent the Stretta procedure. All patients were asked to complete an institutional symptom survey pre-Stretta and at 1, 6, and 12 months after the procedure. Patients rated 7 reflux-related symptoms (heartburn, dysphagia, regurgitation, cough, voice changes/hoarseness, asthma, chest pain) on a 0 (none) to 3 (severe) scale. Data were analyzed using a Wilcoxon matched pairs signed rank test where appropriate.
  
  
  RESULTS
  Complete data were obtained for seven of the eight patients, with a median follow-up of 253 days (range, 67-378 days). One patient was lost to follow-up and not included in our analysis. Symptom scores decreased significantly, with six patients noting both improved typical and atypical symptoms. Overall, six patients (85%) were satisfied with their results.
  
  
  CONCLUSIONS
  Based on this small series, the Stretta procedure significantly reduces subjective symptoms of GERD. The Stretta procedure may serve an important role as an additional management strategy to help manage recurrent GERD after ARS.
