Effect of the transcutaneous electrical stimulation system on esophageal-acid exposure in patients non-responsive to once-daily proton-pump inhibitor: proof-of-concept study

Gastroesophageal reflux disease (GERD) is a common disorder. Overall, ≤35% of GERD patients fail the standard dose of proton-pump-inhibitor (PPI) treatment. Due to the high prevalence and low satisfaction rate with treatment failure, there is an unmet need for new treatment. Our aim was to evaluate whether the use of the transcutaneous electrical stimulation system (TESS) can reduce esophageal-acid exposure in GERD patients unresponsive to...
