Feasibility study of a novel wireless localization technique using radiofrequency identification markers for small and deeply located lung lesions.

ABSTRACT:

Objectives

To evaluate the safety and efficacy of a novel wireless localization technique that uses radiofrequency identification markers for small and deep lung lesions.

Methods

Preliminary use of the device was retrospectively evaluated in 2 Japanese centers. Under general anesthesia, a marker was placed as close as possible to the tumor via computed tomography-guided bronchoscopy in a hybrid operation theater. Surgeons located the marker without lung palpation using a detection probe the tone of which changed to indicate the marker-probe distance. Efficacy was defined as functional marker placement (bronchoscopy time and marker position) and deep margin distance.

Results

Twelve markers were placed for 11 lesions (mean size, 6.8 ± 2.7 mm) located at a mean depth fro
