BACKGROUND: Electrical stimulation therapy (EST) of the lower esophageal sphincter (LES) is a novel technique in antireflux surgery. Due to the minimal alteration at the LES during surgery, LES-EST is meant to be ideal for patients with gastroesophageal reflux disease (GERD) and ineffective esophageal motility (IEM). The aim of this prospective trial (NCT03476265) is to evaluate health-related quality of life and esophageal acid exposure after LES-EST in patients with GERD and IEM.
METHODS: This is a prospective non-randomized open-label study. Patients with GERD and IEM undergoing LES-EST were included. Follow-up (FUP) at 12 months after surgery included health-related quality of life (HRQL) assessment with standardized questionnaires (GERD-HRQL) and esophageal functional testing.
RESULTS: According to the study protocol, 17 patients fulfilled eligibility criteria. HRQL score for heartburn and regurgitation improved from 21 (interquartile range (IQR) 15-27) to 7.5 (1.25-19), p = 0.001 and from 17 (11-23.5) to 4 (0-12), p = 0.003, respectively. There was neither significant improvement of esophageal acid exposure nor reduction of number of reflux events in pH impedance measurement. Distal contractile integral improved from 64 (11.5-301) to 115 (IQR 10-363) mmHg s cm, p = 0.249. None of the patients showed any sign of dysphagia after LES-EST. One patient needed re-do surgery and re-implantation of the LES-EST due to breaking of the lead after one year.
CONCLUSION: Although patient satisfaction improved significantly after surgery, this study fails to demonstrate normalization or significant improvement of acid exposure in the distal esophagus after LES-EST.
