A transcutaneous electrical stimulation system (TESS) is effective in reducing both symptoms and esophageal acid exposure time in patients with gastroesophageal reflux disease (GERD), according to a study published online Jan. 23 in Neurogastroenterology & Motility.
Ram Dickman, M.D., from the Rabin Medical Center in Petah Tikva, Israel, and colleagues assessed the effect of TESS on GERD symptoms and acid exposure time. The analysis included 26 patients who had increased acid exposure time (percent total time pH
The researchers found the mean numbers of daily heartburn and regurgitation episodes were 2.55 and 1.40, respectively, which dropped to 0.77 and 0.36, respectively, following TESS. At baseline, mean acid exposure time and DeMeester score were 12.4 and 32.1, respectively, which dropped to 6.0 and 16.2, respectively, following TESS.
“In summary, TESS appears to be safe and effective in reducing esophageal acid exposure and improving heartburn and regurgitation in GERD patients,” the authors write. “A larger prospective, sham-controlled study is currently designed to verify these early results.”
