Do you utilize robotic bronchoscopy to biopsy a lung cavity wall?

This is not a straightforward question with a simple answer. Depending on what’s suspected for the patient, robotic bronchoscopy can certainly be used for the biopsy of the wall of a cavity. For example, if lung cancer is suspected and no other metastatic sites are noted, a biopsy of the wall is warranted. If the infection is higher in differential, I usually suggest a simple BAL if the sample is needed and follow up with imaging studies.
