Staging Aortopulmonary Lymph Nodes With Robotic-Assisted Bronchoscopy: A Case Report and Literature Review.

Abstract

Robotic-assisted bronchoscopy (RAB) has improved lung nodule evaluation, but its feasibility to biopsy aortopulmonary lymph nodes remains underexplored. This study explored the safety and effectiveness of RAB for sampling aortopulmonary lymph nodes suspected of malignancy. We conducted a literature review on RAB for aortopulmonary lymph node biopsy and present a case of a patient with a history of malignancy. Using the Ion Endoluminal System, we navigated to the anterior segment of the left upper lobe to access a subaortic lymph node in a patient with a history of mantle cell lymphoma. Biopsy confirmed disease recurrence. Our literature review identified seven patients who underwent RAB to assess aortopulmonary lymph nodes, with most findings showing small-cell lung cancer. Our study reports an 88% diagnostic yield, and no complications associated with the procedure. RAB is a safe and effective approach for biopsying aortopulmonary lymph nodes.
