Gastroesophageal diseases with reflux can cause numerous pulmonary complications (bronchospasm crisis, bronchitis, pneumonias, lung abscesses). These manifestations are very frequent in the hiatal hernias and in some series have reached up to 46 percent of the cases studied. Recently it has been suggested that microaspirations, repeated over a long period of time, may cause an alteration of the pulmonary interstitium and the consecutive development of a clinical and roentgenologic picture similar to pulmonary fibrosis. The aspirations are produced more frequently at night, favoured by the lying down position and because of it the patients present attacks of nocturnal cough. In this paper, two patients who presented the association of pulmonary fibrosis and hiatal hernia with esophageal relux are described. The first case was diagnosed early; he had minimal radiographic anomalies and the disappearance of the respiratory symptomatology was achieved by means of the medical treatment of the esophageal reflux. The second case was in a very advanced stage with severe respiratory insufficiency and gastrointestinal manifestations of many years' evolution. Both patients had been diagnosed as having idiopathic pulmonary fibrosis. Although there is no experimental proof of the "reflux-fibrosis" theory, we think that this possibility should be kept in mind before diagnosing the interstitial pulmonary pattern as idiopathic, especially in the cases of only slight radiographic and functional involvement susceptible to improvement with correction of the esophageal reflux.
