Background In our previous case report of circumferential mucosal resection for short-segment Barrett's esophagus with high-grade dysplasia, symptoms of gastro-esophageal reflux disease (GERD) were significantly improved. This observation suggests that anti-reflux mucosectomy (ARMS) could represent an effective anti-reflux procedure, with the advantage that no artificial devices or prostheses would be left in situ.Methods In this pilot study, 10 patients with treatment-refractory GERD received ARMS, 2 of whom circumferential, and the remaining 8 crescentic.Results Key symptoms of GERD improved significantly after ARMS. In the DeMeester score, mean heartburn score decreased from 2.7 to 0.3 (P=0.0011), regurgitation score from 2.5 to 0.3 (P=0.0022), and total score from 5.2 to 0.67 (P=0.0011). At endoscopic examination, the flap valve grade decreased from 3.2 to 1.2 (P=0.0152). In 24-h esophageal pH monitoring the fraction of time at pH <4 improved from 29.1% to 3.1% (P=0.1). Fraction time absorbance more than >0.14 of bile reflux was controlled from 52% to 4% (P=0.05). In 2 cases of total circumferential resection, repeat balloon dilation was necessary to control stenosis. In all cases, proton pump inhibitor prescription could be discontinued with no ill effects.Conclusion This initial case series demonstrated the potential anti-reflux effect of ARMS, with a crescentic mucosal resection appearing adequate. Further longitudinal study of patients without sliding hiatus hernia will be required to establish ARMS as an effective technique to control GERD in this setting.Keywords Gastroesophageal reflux disease, endoscopic treatment, anti-reflux mucosectomyAnn Gastroenterol 2014; 27 (4): 346-351 (EN)
