[Esophageal manometry in patients with sliding hiatal hernia].

This presents the method to be followed for the valuation of the gastro-esophagic function in patients with sliding hiatal hernia, twenty-one patients with this diagnosis were studied through X-Rays. Besides gastric and esophagic endoscopy, a complete clinical examinations was made to compare the information obtained from the studies, with the direct measurement of the contractions of the esophagus and the lower sphincter through conventional manometric methods. The relationship between the simptoms and the clinical procedures done in the patients were observed as was the usefulness of esophagic manometry to detect not only the direct pressure of the gastro-esophagic sphincter, but also to determine the concurrent motor changes that can occur in patients which show hiatal hernia. The benefit of this studies to decide the therapeutic handling, specially surgical, is discussed.
