Abstract
Seven patients with iatrogenic esophageal-pleural fistulas are described and the differences in radiographic and physical findings in these patients and in patients with esophageal perforation with mediastinitis are emphasized. Radiographic findings in patients with esophageal-pleural fistulas are pneumothorax, hydropneumothorax and localized pneumonitis. These fistulas can mimic other inflammatory supradiaphragmatic or infradiaphragmatic processes. Clinical and radiographic signs may be subtle and active investigation is needed to establishthe diagnosis of esophageal-pleural fistula in patients who have undergone esophageal manipulation.
