Gastroesophageal reflux disease (GERD) is a common, chronic disease of the digestive system. In recent years, endoluminal therapy for GERD has become a research hotspot. The reduced anti-reflux barrier function plays an important role in the occurrence of GERD. Peroral endoscopic therapy can improve the defect of anti-reflux barrier function. According to the involved layers, the endoscopic therapy can be classified as transmural which represented by transoral incisionless and transoral incisionless fundoplication, and non-transmural which represented by peroral endoscopic cardia constriction and radiofrequency ablation. This article reviews the progress of endoscopic non-full-thickness therapy for GERD in recent years, and introduces the action mechanism of peroral endoscopic therapy of GERD, the therapy of the mucosal layer and muscle layer of anti-reflux barrier, and other treatments. The purpose is to provide a reference for further exploring suitable endoscopic treatment of GERD.
