Why do GERD patients with hiatus hernia reflux?

GERD patients with hiatus hernia have excess reflux due to mechanisms other than transient LES relaxations, according to research in December's Gastroenterology

A team from the University Medical Center, Utrecht, The Netherlands investigated the effect of a sliding hiatus hernia on the mechanisms underlying spontaneous gastroesophageal reflux.

Twelve gastroesophageal reflux disease (GERD) patients with, and ten GERD patients without, hiatus hernia were studied for 24 hours.

Combined esophageal pH and manometric recordings of the pharynx, lower esophageal sphincter (LES), and stomach were performed. For this a multiple-lumen assembly, incorporating a Dent sleeve connected to a portable water-perfused manometric system and a pH glass electrode, was used.

GERD patients with hiatus hernia vs. those without:
Esophagal acid exposure:
7.6% vs. 3.3%
Reflux episodes:
3.1/h vs. 1.8/h

The group found that patients with hiatus hernia had greater esophageal acid exposure (7.6 vs. 3.3%) and more reflux episodes (3.1 vs. 1.8/h) than those without.

LES pressure, the incidence of transient LES relaxations (TLESRs), and the proportion of TLESRs associated with acid reflux were comparable in both groups. Both groups had equal numbers of reflux episodes associated with TLESRs and swallow-associated prolonged LES relaxations.

Patients with hiatus hernia had more reflux associated with low LES pressure, swallow-associated normal LES relaxations, and straining during periods with low LES pressure.

Dr. Margot Van Herwaarden concluded on behalf of the group, "The excess reflux in GERD patients with hiatus hernia, compared with those without, is caused by malfunction of the gastroesophageal barrier during low LES pressure, swallow-associated normal LES relaxations, deep inspiration and straining."
