%X <B>BACKGROUND: </B>Treatment options for gastroesophageal reflux disease (GERD) that is unresponsive to proton pump inhibitors (PPIs) remain limited. Therefore, we compared the therapeutic effects of anti-reflux mucosectomy (ARMS) and Stretta radiofrequency (SRF) for intractable GERD in over 400 individuals who underwent either procedure.<BR><B>METHODS: </B>We conducted a retrospective study between 2016 and 2023 to evaluate the effectiveness of SRF and ARMS treatments for refractory GERD. The primary measure of success was the change in the GERD questionnaire (GERDQ) score. The secondary outcomes were various GERD-related indicators, including endoscopic Los Angeles (LA) classification, Hill's type-based flap valve grade (FVG), EndoFLIP™ distensibility index (DI), rate of PPI discontinuation, resolution rate of Barrett's esophagus, and incidence of adverse events.<BR><B>RESULTS: </B>The ARMS group included patients with high GERDQ scores, FVG, LA grade, and Barrett's esophagus. Both groups had similar rates of improvements in GERDQ score (P = 0.884) and PPI withdrawal (P = 0.866); however, the ARMS group had significantly more side effects and improvements in the median change in GERDQ score (P = 0.011), FVG (P < 0.001), LA grade (P < 0.001), EndoFLIP™ DI (P < 0.001), and resolution of Barrett's esophagus (P < 0.001).<BR><B>CONCLUSIONS: </B>The ARMS group had a greater GERDQ score improvement than the SRF group but had symptom relief and PPI discontinuation rates similar to those of the SRF group. However, objective measures, including EndoFLIP™ DI and endoscopic evaluations, were better in the ARMS group than in the SRF group.
