Endoscopic antireflux treatment: fact, fiction or future?

Medical therapy with proton pump inhibitors (PPIs), aside from surgery, is the established and most effective treatment approach for chronic gastroesophageal reflux disease (GERD). Recently developed endoscopic antireflux procedures may be an alternative for a subset of patients with uncomplicated, mild GERD. Given the perioperative morbidity and mortality risk of laparoscopic fundoplication, less invasive semi-surgical and flexible endoscopic techniques may be an option for patients who cannot or wish not to take long-term medication. These clinical procedures include endoscopic suturing devices, focal radiofrequency coagulation in the cardia and bioimplants. While many of these techniques have shown good results in preliminary studies, long-term results are not yet available and therefore all such procedures have to be considered experimental. Their effectiveness will need to be compared with that of established treatment forms.
