The purpose of this study was to gather long-term follow-up data on patients treated with the Plicator in a previous open-label multi-center study. Originally, 64 subjects were treated at seven U.S. sites. A subset of those patients were subsequently reassessed via symptom questionnaires in this long-term (60-month) follow-up analysis. The initial open-label study was completed and officially closed at the completion of 1-year follow-up. This current study was designed to collect long-term follow-up data on previously plicated subjects all of whom were recruited de novo from the original study population. Study endpoints were prospectively defined. The primary study objectives were to assess: reduction in GERD symptoms through analysis of the GERD Health Related Quality of Life (HRQL) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS); reduction in use of GERD medications, and change in overall physical and psychological health as measured by the Short Form Health Survey (SF-36).
