Abstract
A fistulous communication between an esophageal traction diverticulum and the tracheobronchial tree appears to be of rare occurrence, only 21 cases having been found on review of the literature. A patient with such a lesion and symptoms of an esophagobronchial fistual of 21 years' duration recently came under our observation. Resection of the traction diverticulum of the esophagus and the superior segment of the right lower lobe resulted in complete cure. A fistulous communication between a traction diverticulum and the tracheobronchial tree may result from either perforation of an inflamed and ulcerated diverticulum or an extension of the original inflammatory process which iniated diverticulum formation. These traction diverticula are unrelated to Zenker's, or pulsion, diverticulum of the cervical esophagus, which is merely an outpouching of esophageal mucosa and submucosa between the pharyngeal constrictor muscles. The traction diverticula are caused by contraction of inflammatory lesions between the esophagus and the peribronchial
