Clinical efficacy of endoscopic antireflux mucosectomy vs. Stretta radiofrequency in the treatment of gastroesophageal reflux disease: a retrospective, single-center cohort study

BACKGROUND: Currently, antireflux mucosectomy (ARMS) and Stretta radiofrequency (SRF) are the most commonly used minimally invasive antireflux therapies. To date, there have not been any reports comparing ARMS and SRF. Our aim was to compare the clinical efficacies of these two therapeutic methods. METHODS: We analyzed data from gastroesophageal reflux disease (GERD) patients, including 39 who received ARMS treatment and 30 who received SRF treatment between January 2020 and May 2021. Symptom control, gastroesophageal reflux disease questionnaire (GERDQ) score, gastroesophageal reflux disease health-related quality of life (GERD-HRQL) score, proton pump inhibitor (PPI) withdrawal, and PPI reduction were analyzed and compared. RESULTS: After 6 months of follow-up, the results showed that both therapies were effective in improving symptoms and quality of life. No difference was found between the ARMS group and SRF group in GERDQ score, GERD-HRQL score, PPI withdrawal rate, or PPI reduction rate (P>0.05). There was no significant difference in the PPI withdrawal rate between the two therapies among patients with gastroesophageal flap valve (GEFV) grade II and grade III (P>0.05), but the PPI withdrawal rate in the ARMS group was significantly higher than that in the SRF group among patients with GEFV grade IV (P<0.05). CONCLUSIONS: The clinical efficacies of ARMS and SRF 6 months postoperation were equivalent. The results showed that both ARMS and SRF treatment were acceptable for patients with GEFV grades II and III, while ARMS should be selected for patients with GEFV grade IV.
