Records of 256 patients who underwent transbronchial biopsies over a seven year period were analyzed. About 75% were males and about 50% were in the 41-60 age group. In 79 out of the 256 (30.9%), this procedure confirmed clinical suspicion while in 24 others, the biopsy confirmed the diagnosis which had not been clinically considered mostly likely; altogether 103 (40.2%) out of 256 patients had a diagnosis established. Suspected malignancy (34.4%), interstitial lung fibrosis (23.8%), sarcoidosis and tuberculosis (14.5% each) were the main reason for performing the procedure. Complications were mainly bleeding in 14 (5.5%) and pneumothoraces in three patients.
