Diagnosis of peripheral lung cancer by selective bronchography.

Abstract

Bronchograms of 50 cases of peripheral lung cancer were studied, and their diagnostic value and limitations are discussed. The diagnostic value was: 88 % in the 4th order bronchus, 80 % in the 5th order bronchus, 55 % in the 6th order onward peripherally. On the average the diagnostic rate with selective bronchography was 84 %. Due to poor bronchography, accurate diagnosis could not be made in 6 % of cases. Differential diagnosis of 34 chronic inflammatory lesions is also discussed.
