Abstract: | The present study was carried out to evaluate the diagnostic usefulness of stationary esophageal manometry in 263 patients divided into three groups: 150 patients with reflux symptoms, 68 with dysphagia, and 45 with non-cardiac chest pain. Patients with endoscopic abnormalities were excluded. Standard manometry was performed following the station pull-through technique. In the group of patients with reflux symptoms 40.7% had a normal manometry and 57.3% had abnormalities, being the most frequent (43%) hypotensive lower esophageal sphincter. In the dysphagia group, 20.6% of manometries were normal and 79.4% were abnormal, of which achalasia was the most frequent disorder (53.7%). In the case of non-cardiac chest pain, 42.2% of patients had a normal manometry and 57.8% an abnormal one, of which hypotensive lower esophageal sphincter was the most frequent abnormality. A significant higher proportion of manometric alterations were found in the dysphagia group compared to reflux symptoms and non-cardiac chest pain (p < 0.05). No statistical differences were found between the reflux and the non-cardiac chest pain groups. Manometry yields a higher diagnostic value in patients with dysphagia, and therefore manometry should be performed routinely after the exclusion of any organic esophageal disease. Manometry is not a first-choice functional diagnostic test in the study of patirnts with gastroesophageal reflux or non-cardiac chest pain. |
