[Thoracic pain possibly of esophageal origin. Results of a prospective study].

We have studied the prevalence of esophageal pathology, by means of esophagogram, esophagogastroscopy, manometry, 24-hours ambulatory pH measurement and acid perfusion of the esophagus, in 44 patients with thoracic pain suggestive of angina. Esophageal pathology was demonstrated in 30 (68.3%) cases; 25 patients were diagnosed of reflux and 5 of primary motor alteration. All the patients received specific treatment; the response to treatment was good in 22 of them (17 with reflux and 5 with motor alterations). In conclusion, esophageal pathology is a common cause of thoracic pain, and reflux is the most frequent finding.
