Abstract Introduction  Magnetic sphincter augmentation (MSA) is a safe and effective treatment for patients with gastroesophageal reflux disease (GERD). MSA was initially indicated for patients with GERD and concomitant hiatal hernias  2 cm) on videoesophagram or endoscopy. Results  Seventy-nine patients (53% female) with a median age of 65.56 (58.42–69.80) years were included. Median follow up was 2.98 (interquartile range 1.90–3.32) years. Median DeMeester scores decreased from 42.45 (29.12–60.73) to 9.10 (3.05–24.30) (p  14.72, and a hiatal hernia ≥ 3 cm per esophagogastroduodenoscopy (EGD) or videoesophagram (VEG) [21]. Patients were not considered for surgery if they had severe esophageal dysmotility (distal contractile integral
