Magnet-assist endoscopic augmentation of the lower esophageal sphincter for treatment of gastroesophageal reflux disease: cadaveric and survival studies in a porcine model (with video).

Endoscopic augmentation of the LES using a new MCD was feasible, safe and reversible with significantly increased LES pressures recorded. Future studies are needed to enhance durability. These preliminary results on a reversible technique are promising and may represent an attractive alternative to endoluminal GERD therapy.
