Wahidi et al recently published a guideline and expert panel report in CHEST (March 2016) reviewing the technical aspects of endobronchial ultrasonography (EBUS) and EBUS-guided transbronchial needle aspiration. We would like to acknowledge the authors’ thorough evidence-based review of the topic and their outstanding work in publishing the first guidelines to summarize a body of literature that has become quite large over recent years.

We would like to point out that a retrospective study we performed concerning nasal insertion of EBUS at our institution has been incorrectly referenced and should be corrected. The correct reference is available in the reference list.

Also, in the guideline statement, the authors conclude that there is no available randomized trial comparing nasal and oral EBUS scope insertion. Out of interest, we would like to mention a randomized study that we recently completed and published comparing the two routes of insertion. A total of 110 subjects were randomized in each group. Our study did not find any significant difference regarding patient comfort, satisfaction, and willingness to repeat the procedure. The two groups also did not differ regarding EBUS-transbronchial needle aspiration diagnostic yield and specimen adequacy rate. It is worth noting that the EBUS bronchoscope could not be nasally inserted in 24.5% of patients in the nasal group. We thus concluded that both routes confer a high degree of comfort with similar complication rates and diagnostic yields.

Although EBUS is performed mostly through the nasal route at our center, we believe both routes to be equivalent and that physician and, most importantly, patient preferences should dictate the route of insertion.
