FUNDAMENTAL advances in anatomy, physiology, and pathology in relation to bronchoesophagology were scarce in 1954. A revival of interest in bronchial adenoma brought out the increasing use of surgical excision in the treatment. Diseases of the esophagus continued to receive more attention, particularly regurgitant esophagitis.
Croxatto and Lanari1 considered all cases of bronchiectasis, whether acquired, primary, or secondary, to be caused by bronchial obstruction. Experiments performed on dogs revealed that complete bronchial obstruction leads to bronchoalveolar apneumatosis. The secreted mucus could not find an external outlet, and so the bronchus became dilated, producing the first phase of obstructive bronchiectasis. The mucus bronchodilatation was found to either disappear early or become permanent at a later time, leading to bronchiectasis.Radioactive barium sulfate particles were administered intratracheally to rats by Cember and co-workers2 to study pulmonary penetration and distribution. Although the particles were generally found in all lobes
