Endoluminal methods of treating gastroesophageal reflux disease.

Several endoluminal methods of treating gastroesophageal reflux disease (GERD) have either been approved, or are under investigation and development. This review outlines the two approved methods (Bard's endoluminal sewing machine and Curon's Stretta radiofrequency treatment), and describes the available data on new methods under investigation. The various methods can be divided into three broad categories: methods that create a controlled stricture, methods that bulk the gastroesophageal junction, and methods that attempt to create a fundoplication. The pros and cons of each method are discussed. Unlike medical treatment, these methods attack the reflux itself, not just the symptoms. This is a promising approach. However, the controlled stricture and bulking methods do not approach the success rate of a standard fundoplication.
