Structured PICO

Population

Patient requiring aortopulmonary window lymph node sampling for suspected lung cancer

Intervention

Robotic-assisted transbronchial biopsy of aortopulmonary window lymph nodes using cone-beam CT guidance

Outcome

Successful diagnosis of small cell lung cancer without surgical mediastinal biopsy

Robotic-assisted transbronchial biopsy with cone-beam CT guidance is a feasible minimally invasive alternative to surgical mediastinal biopsy for sampling aortopulmonary window lymph nodes.

Main Result

Absolute Event Rate: 0% vs 0%

Abstract

ABSTRACT Sampling aortopulmonary window lymph nodes is technically challenging and often requires surgical approaches. We report a minimally invasive robotic‐assisted transbronchial biopsy of AP window lymph nodes using cone‐beam CT guidance, enabling diagnosis of small cell lung cancer without surgical mediastinal biopsy.
