Abstract

Magnetic sphincter augmentation with the LINX® Reflux Management System is a novel device made of an expansible bracelet of magnetic beads designed to be placed around the gastroesophageal junction with a standardized laparoscopic procedure. This device can augment the function of the lower esophageal sphincter by preventing premature opening of the sphincter, thereby preventing reflux of gastric contents into the lower esophagus, while maintaining the ability to permit the passage of the food bolus and to belch and vomit. Magnetic sphincter augmentation has demonstrated in multiple studies consistent improvements in patient symptoms as measured by the GERD-HRQL instrument, freedom from PPIs, and improving objective pH control. These outcomes confirm that MSA is an effective method of controlling troublesome GERD symptoms. Future studies are required to determine its role outside of the initial indications for its use.
