Rate of new findings in diagnostic office bronchoscopy

Objectives

Awake Flexible Tracheobronchoscopy (FTB) is an alternative to rigid bronchoscopy or sedated flexible bronchoscopy and allows an awake examination of the tracheobronchial tree. We hypothesized that the ability to perform office bronchoscopy as the need arises during a clinic visit would lead to a high rate of previously undiagnosed and clinically relevant findings. This study reports the rate and nature of such findings for this procedure at our institution.

Study Design

Retrospective chart review.

Methods

The records of 127 adult patients evaluated at the voice and swallowing disorders clinic between June of 2012 and January of 2015 were reviewed. New findings were defined as new pathology visualized during FTB exam that was not previously diagnosed by means of other diagnostic modalities.

Results

A total of 233 scope procedures (84 transnasal bronchoscopies and 149 tracheoscopies) were reviewed, 232 of which were completed and one of which was incomplete due to severe subglottic stenosis. New, clinically relevant findings were seen in 57% of transnasal bronchoscopies (48 of 84) and 21% of tracheoscopies (32 of 149). All of these findings provided additional information directing workup or resulted in a change in patient management.

Conclusion

Office-based evaluation of the tracheobronchial tree yields a high rate of new findings. In our study, office bronchoscopy had a 57% rate of new findings and was performed without complications. The utility of tracheoscopy was also apparent in its ability to quickly and safely examine the trachea, with a 21% rate of new findings.
