Tracheobronchial necrosis after caustic ingestion.

Between 1968 and 1988, 679 patients were hospitalized for ingestion of caustic substances, and 87 had severe caustic burns of the entire esophagus, together with panparietal necrosis. Twenty-one of them had tracheobronchial necrosis with perforation. Fifteen have not been operated on; six have had operations, with success in four. We describe an original technique for repairing these tracheobronchial perforations with a pulmonary patch.
