CT-guided preoperative localization of nonpalpable pulmonary lesions with a specifically designed device: evaluation of safety and efficacy

■ This method enables surgeons to visually identify the lesion pathway without intraoperative imaging, enhancing precision and workflow.
■ A practical, cost-effective alternative to high-end technologies such as electromagnetic navigation bronchoscopy and hybrid operating rooms.
■ Metallic wires offer excellent intraoperative visibility on the lung surface, supporting their clinical utility.
■ All nonpalpable nodules were successfully resected, with no complications related to the preoperative localization procedure.
■ CT-guided preoperative localization of nonpalpable pulmonary lesions using a purpose-built device demonstrates both safety and efficacy.

ABSTRACT

Objective:

This study aimed to evaluate the percutaneous preoperative localization of lung masses suspected to be nonpalpable with a wedge-shaped wire (Somatex® Lung Marker System).

Methods:

Patients underwent CT-guided lung mass localization with the Somatex® Lung Marker System prior to resection of pulmonary lesions by video-assisted thoracoscopy. The characteristics of the lung masses, complication profiles, histological analysis, and surgical success were reviewed.

Results:

Forty lung masses were percutaneously localized preoperatively in 38 patients. Eight patients did not have malignancies. Major complications were not observed. All lung masses were fully resected after preoperative localization.
