A Magnetic Sphincter Device Shows Promise for GERD

Esophageal acid exposure was significantly reduced in 64% of patients who had the device surgically implanted.

In patients with gastroesophageal reflux disease (GERD) who experience only partial response to proton-pump inhibitor (PPI) agents, antireflux surgery (e.g., fundoplication) is an option to restore functionality to the lower esophageal sphincter (LES). However, 5% to 8% of patients experience new postsurgical symptoms, including dysphagia, gas, and bloating. Now, researchers investigate the safety and efficacy of an alternative surgical treatment for GERD — laparoscopic placement of a magnetic device around the distal esophagus.

As part of a 5-year, industry-funded, prospective study, 100 patients underwent implantation of the device, which provides magnetic force to augment the barrier function of the LES and prevent gastric reflux. Alterna…
