Long-term results of radiofrequency energy delivery for the treatment of GERD: sustained improvements in symptoms, quality of life, and drug use at 4-year follow-up.
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.


METHODS
Prospective single-center case series.


METHODS
Academic endoscopy referral center.


METHODS
Adults with GERD symptoms and partial response to daily antisecretory medication.


METHODS
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).


CONCLUSIONS
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.
