It is generally admitted that artificial pneumothorax is not only the most widely applicable method of collapsing the lung in the treatment of pulmonary tuberculosis but also the most valuable. Unfortunately, pleuritic adhesions are almost invariably present in cases in which the patients require pneumothorax treatment and constitute the greatest obstacle to a satisfactory end-result.
As a result of experience in the treatment of approximately 1,400 patients with pulmonary tuberculosis with artificial pneumothorax during the past eighteen years, my co-workers and I are convinced of the importance of establishing a type of pneumothorax which within a few months will give the diseased lung sufficient functional rest, collapse or compression to render it no longer a source of tuberculotoxemia or tubercle bacilli-laden sputum.
The importance of a satisfactory collapse of the lung is strikingly shown in the accompanying table. A careful review of the clinical records and stereoroentgenograms in 245 cases
