Methods: GERD was evaluated by the Modified Italian Gastroesophageal reflux disease—Health-Related Quality of Life
(MI-GERD-HRQL) questionnaire, pH-manometry, endoscopy, and Rx-esophagogram, before and 12 months after

difference observed at pH-manometry was the median DeMeester score, from 5.7 to 22.7 (P = .0026). De novo GERD
