Anti-Reflux Mucosal Ablation(ARMA) and Anti-Reflux Mucosectomy(ARMS) in Gastroesophageal Reflux Disease

According to the current published data and treatment mechanism, ARMS may led to more stenosis while ARMA may be less effective in long term follow-up. The changes of patient's life quality , UGI tract microbiota before and after different endoscopic treatment are also limited. So we want to conduct a exploratory prospective randomized controlled study in evaluating the mucosal healing, demand of PPI, life quality, emotion status, sleep quality, esophageal motility/ acid exposure and saliva microbiota between chronic GERD patients receiving ARMS and ARMA treatment.
