Antireflux surgery with a magnetic sphincter augmentation device (MSAD) restores the competency of the lower esophageal sphincter with a device rather than a tissue fundoplication. As a regulated device, safety information from the published clinical literature can be supplemented by tracking under the Safe Medical Devices Act. The aim of this study was to examine the safety profile of the MSAD in the first 1000 implanted patients. ⋯ The safety analysis of the first 1000 patients treated with MSAD for gastroesophageal reflux disease confirms the safety of this device and the implantation technique. The overall event rates were low based on data from 82 institutions. The MSAD is a safe therapeutic option for patients with chronic, uncomplicated gastroesophageal reflux disease.
