Novel computed tomography-guided microcoil device achieved technical success in 97% of pulmonary nodule localizations
The utility of a modified microcoil device for pulmonary nodule localization: a single-centre prospective study.
Video-assisted thoracoscopic surgery (video-assisted thoracoscopic surgery) is the standard treatment for small pulmonary nodules (small pulmonary nodules), yet accurate localization of non-palpable lesions remains challenging.
This study evaluated the efficacy, feasibility, and safety of a novel computed tomography (computed tomography)-guided microcoil localization system for preoperative small pulmonary nodules management.
In this prospective single-arm study, 178 patients with 231 small pulmonary nodules (≤10 mm, cN0) underwent preoperative localization followed by video-assisted thoracoscopic surgery.
Coil was placed accurately near the nodule, without failure, in 97 of 100 cases
The mean localization time was 4.4 min, and the median coil-to-nodule distance was 4.9 mm.
Complications were infrequent and mild: asymptomatic pneumothorax occurred in 12 cases (5.2%) and minor hemorrhage in 11 (4.8%), none of which required treatment; these rates compare favorably to those of conventional hook-wire systems.
Patient pain was negligible, and 97.4% of coils were retrieved with the specimen.
Failures occurred in 3.0% of nodules due to wire fracture, dislodgement, or displacement.
This novel microcoil system demonstrated high efficacy, procedural efficiency, and excellent safety, addressing key limitations of existing localization methods.
