Transoral incisionless fundoplication with Esophyx for treatment of gastro-esophageal reflux disease

Gastro-oesphageal reflux disease results primarily from the loss of an effective antireflux barrier, which forms a mechanical barrier against the retrograde movement of gastric content. This review describes the technique of performing a transoral incisionless fundoplication with the EsophyX(®) device. Transoral incisionless fundoplication reconfigures the tissue so as to establish serosa-to-serosa plications which include the muscular layers, and construct 3-5cm long valves 200-300° in circumference. The steps of the technique, as well as complications and their management are described in detail, and a recent literature review is also provided. At present, available prospective cohort studies indicate that transoral incisionless fundoplication using the EsophyX(®) device may be effective in approximately half PPI-responsive gastro-oesphageal reflux disease for up to 3 years' follow-up, without troublesome procedure-related persistent side effects.
