Does Hiatus Hernia Affect Competence of the Gastroesophageal Sphincter?
Abstract
To measure the effect of a sliding (concentric) hiatus hernia on gastroesophageal sphincter competence, 75 patients were studied: 25 patients without esophageal symptoms and without hiatus hernia (Group A); 25 patients without esophageal symptoms but with hiatus hernia (Group B); and 25 patients with symptoms of severe gastroesophageal reflux, with or without a hiatus hernia (Group C). In Group C, 12 patients had a hiatus hernia, and 13 did not. Symptomatic patients were readily separated from asymptomatic ones both by a weaker base-line sphincter strength and by decreased sphincteric response to the stimulus of an increase in intraabdominal pressure. However, in neither the asymptomatic nor the symptomatic groups of patients could any effect of hiatus hernia be found. A hiatus hernia apparently has no effect on gastroesophageal sphincter competence. The rationale for surgical repair of hiatus hernia in patients with gastroesophageal reflux must therefore be questioned.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
