Endoscopic therapy for gastroesophageal reflux disease: a systematic review

The high prevalence of gastroesophageal reflux disease (GERD) in Western societies has accelerated the need for new modalities of treatment. Currently, medical and surgical therapies are widely accepted among patients and physicians. The minimally invasive treatment revolution, however, has stimulated several new endoscopic techniques for GERD. Up to now, the data is limited and further studies are necessary to compare the advantages and disadvantages of the various endoscopic techniques to medical and laparoscopic management of GERD. This systematic review reports the efficacy and durability of various endoscopic therapies for GERD whilst the potential for widespread use of these techniques is also discussed. Despite the limited number of studies and remarkable differences between various trials, strict criteria were used for the pooled data presented and an effort was made to avoid bias by including only studies that used off-antisecretory medication scoring as baseline and intent to treat.
