Another interesting finding was the relatively low rate of routine use of transtracheal/transbronchial needle aspiration (TBNA) in malignant and nonmalig-nant diseases (11.8 percent and 2.3 percent, respectively). Poor results were noted by a significant number. The majority of those who wrote individual comments mentioned damage to the bronchoscope as one of the major problems with this procedure. These comments reflect the reported experience with TBN A-needle-induced damage to the bronchoscope. Others complained about problems with the needle, unacceptability of the specimens to the pathologist, and lack of training in the procedure. Of all the individual procedures, TBNA received the most negative comments. The number of physicians who routinely used frozen-section examination of biopsies was quite low at 2.6 percent. This is possibly due to the organization of individual pathology laboratories, lack of appropriate facilities, and the distance of the pathology laboratories from the bronchoscopy suite. Videobronchoscopy was used routinely by 14 percent of the respondents and rarely by 74 percent. Videobronchoscopy is very helpful in simultaneous bronchoscopy training of several physicians.
