Long-term results of electrical stimulation of the lower esophageal sphincter for the treatment of gastroesophageal reflux disease

In this prospective study of patients with GERD moderately responsive to proton pump inhibitors (PPIs), an electrical device to stimulate the lower esophageal sphincter was implanted and results were assessed at 1 year.  GERD health related QOL scores were reduced  to 2 compared to 9 on PPIs and 23 off PPIs prior to implant.  Acid exposure was reduced from 10% to 3.3%.  96% of patients required no PPIs at 1 year.
