Concurrent videofluoroscopy and manometry were used to analyze esophageal emptying during barium swallows in 22 patients with axial hiatal hernias and in 14 volunteers. Subjects were divided into three groups: (a) volunteers with maximal phrenic ampullary length <2 cm (controls); (b) patients or volunteers with maximal ampullary/hiatal hernia length ≥2 cm that reduced between swallows (reducing-hernia group); and (c) patients with hernias that did not reduce between swallows. Complete esophageal emptying without retrograde flow was achieved in 86% of test swallows in the controls, 66% in the reducing-hernia group, and 32% in the nonreducinghernia group (P< 0.05). Impaired emptying in the reducing-hernia group was attributable to “late retrograde flow,” whereby barium squirted retrograde from the hernia during emptying. Impaired emptying in the nonreducing-hernia group was attributable to “early retrograde flow” that occurred immediately after LES relaxation. The nonreducinghernia group also had longer acid clearance times than the controls (P< 0.05). We conclude that gastroesophageal junction competence is severely impaired in patients with nonreducing hiatal hernias, suggesting a mechanism whereby this subgroup of hiatal hernia is involved in the pathogenesis of reflux disease.
