Abstract
While medical therapy, particularly with proton pump inhibitors, is effective for the large majority of patients with reflux disease, there remains a subset of patients who are dissatisfied, due to cost, side effects of medications, or persistent symptoms such as regurgitation. For this population, surgical fundoplication has been, and remains, an appropriate option. A new class of endoluminal interventions, attempting to create a mechanical antireflux barrier, has emerged recently. Three such devices are currently approved and available, and a number of others are in various stages of evaluation. This article will review the approved technologies, as well as selected promising emerging ones, with particular emphasis on the scientific evidence available to date supporting their efficacy.
