Cystic intrathoracic derivatives of the foregut and their complications

Abstract

It is suggested that these lesions should be classified into 3 main categories based on embryology: bronchogenic cyst (resulting from a defect of lung budding), intramural oesophageal cyst (true duplication), and enteric cyst (resulting from the split notochord syndrome). A series of 41 patients is reported. Seven patients suffered complications, and in 2 cases these nearly resulted in the death of the patient. These complications are described and their serious import is used to emphasize the desirability of surgical removal of all these foregut derivatives before complications ensue.
