    Abstract:
    PURPOSE: To compare the safety and efficacy of hook wire versus microcoil localization of pulmonary nodules prior to video-assisted thoracoscopic resection (VATS). MATERIALS AND METHODS: A retrospective comparative review was conducted of 46 patients (26 hook wire and 20 microcoil) who underwent computed tomography fluoroscopic-guided nodule localizations prior to VATS in a single center between January 2012 and August 2016. Nodule characteristics, procedural details, clinical outcomes, and pathologic findings were collected. Baseline characteristics and lung nodule distribution were not significantly different between the 2 groups. Nodule sizes ranged from 2 mm to 28 mm and were similar between groups. Twenty-nine patients (63%) were male, with mean (standard deviation) age of 61 (11) years. Adverse events were classified using standard criteria. Patients were followed for up to 90 days, and the clinical outcomes were compared. RESULTS: Successful resection of nodules was achieved in all patients. Twelve cases of displacement of the hook wire were observed compared to only 1 in the coil group (P < .01). The total complication rate was lower in the coil group (25% vs 54%, P = .04). Two patients required transition to thoracotomy in the hook wire group, compared to none in the coil group. Median blood loss was similar in both groups (median loss, 20-22 mL). One patient had positive margins in the hook wire group. There was a nonsignificant trend toward longer hospital stay and higher major complication rates after hook wire localization (P = .4). CONCLUSIONS: Pulmonary nodule localization with coils prior to VATS resection demonstrated fewer displacements and fewer perioperative complications compared to hook wires.
