BACKGROUND: The Stretta endoscopic antireflux procedure has effectively controlled symptoms of patients with GERD refractory to proton pump inhibitor (PPI) medication up to 1 year. OBJECTIVE: The aim of this study was to evaluate the efficacy of the Stretta procedure for patients with GERD based on symptom control, quality of life (QOL), and medication use. DESIGN: Prospective single-center case series. SETTING: Academic endoscopy referral center. PATIENTS: Adults with GERD symptoms and partial response to daily antisecretory medication. INTERVENTION: We have used the Stretta procedure for patients with GERD diagnosed by endoscopic or pH testing since 2000. Our primary assessment was a validated health-related QOL score for heartburn and regurgitation and GERD symptoms index performed at baseline, 12, 36, and 48 months after treatment. A secondary outcome measure was the dose and the frequency of antisecretory pharmaceutical use.
RESULTS: We performed the Stretta procedure in 83 consecutive patients with persistent GERD symptoms. Complete matched data for follow-up evaluations are reported at 12, 36, and 48 months. The mean GERD QOL score was 2.4 (baseline), 4.6 (36 months), and 4.3 (48 months, P < .001). The mean GERD symptom score was 2.7 (baseline), 0.3 (36 months), and 0.6 (48 months P < .001). Daily medication usage was 100% (baseline) and 13.6% (48 months, P < .001). LIMITATIONS: Nonrandomized study design, lack of control arm, and lack of 24-hour pH.
CONCLUSIONS: For these GERD patients followed to 4 years, the Stretta procedure was a safe, effective, and durable treatment, with significant and sustained improvements in GERD symptoms, QOL, and PPI elimination.
