INTRODUCTION: Hiatus hernia is characterized by axial separation between the lower esophageal sphincter and the crural diaphragm, and higher reflux burden. Impact on reflux is unclear if such separation is intermittent rather than persistent.
METHODS: Reflux burden off antisecretory therapy was compared between no hernia (n = 357), intermittent hernia (n = 42), and persistent hernia (n = 155) after review of consecutive high-resolution manometry and reflux monitoring studies.
RESULTS: Proportions with pathologic acid exposure was similar between intermittent and persistent hernia (45.2% vs 46.5%, respectively), and both were significantly different from no hernia (28.7%, P ≤ 0.002).
DISCUSSION: Intermittent hiatus hernias are clinically relevant in gastroesophageal reflux pathophysiology.
