Abstract:Abstract: Objective?To evaluate the safety and efficacy of endoscopic anti-reflux mucosectomy (ARMS) for refractory gastroesophageal reflux disease.?Methods?6 patients who underwent anti-reflux mucosectomy from June 2017 to January 2019 were enrolled in this study, and the clinical data were analyzed retrospectively. RSI, GERD-HRQL and dysphagia scores were used before and after the operation for evaluation of curative effect of anti-reflux mucosectomy.?Results?6 patients underwent anti-reflux mucosectomy successfully. No major adverse events such as perforation or bleeding was found in perioperative period. The patients were followed up for at least 6 months, and the longest follow-up time was up to 26 months. RSI and GERD-HRQL scores were (9.7?±?3.9) and (11.3?±?2.3) respectively one month after ARMS (P?0.01), there was statistical significance between preoperative and one month after ARMS. RSI and GERD-HRQL scores were (2.8?±?1.5) and (3.2?±?1.9) respectively 6 months after ARMS (P?0.01), there was also statistical significance between preoperative and 6 months after ARMS. The symptom of dysphagia had not improved one month after ARMS (P?>?0.05), but no patients felt dysphagia 6 months after ARMS [The score is (0.0±0.0), P?0.05].?Conclusion?Anti-reflux mucosectomy is efficient and safe to relieve the symptom of refractory gastroesophageal reflux disease in short term.
