title: A critical review of endoscopic therapy for gastroesophageal reflux disease.
abstract: The US Food and Drug Administration has approved 2 endoscopic devices for treating gastroesophageal reflux disease, and several thousand procedures have been performed to date. At least 6 other endoscopic devices designed to treat gastroesophageal reflux are in various stages of testing and may soon obtain approval for clinical use. Short-term follow-up studies uniformly report improvement in heartburn symptoms and quality-of-life scores, as well as decreases in use of antisecretory medications. However, esophageal acid reflux is not normalized after these treatments, nor is esophagitis improved. Although troubling efficacy and safety issues are currently unresolved, these techniques are becoming routine clinical procedures outside of clinical trials. Unless there is rigorous attention to scientific validation of these techniques, including comparative trials versus conventional treatments, there will remain a cloud of doubt and concern about their role and usefulness in clinical medicine. The rapid incursion of these devices into the clinical marketplace before they have undergone critical scientific scrutiny magnifies the urgency of addressing these issues.
