Preoperative computed tomography-guided localization of pulmonary ground‑glass nodules: a comparison of conventional and soft hook‑wires.

INTRODUCTION

Hook-wire (HW) localization is the most frequently employed approach for preoperative localization of pulmonary ground-glass nodules (GGNs); however, the relative outcomes of conventional and soft HW localization of GGNs remain poorly understood.

AIM

This study sought to compare the safety and efficacy of preoperative computed tomography-guided conventional and soft HW localization of pulmonary GGNs.

MATERIALS AND METHODS

Between January 2023 and June 2024, consecutive patients with pulmonary GGNs underwent conventional or soft HW localization prior to video-assisted thoracoscopic surgery. Safety and clinical efficacy of these 2 localization strategies were compared.

RESULTS

In total, 88 patients underwent conventional HW localization of 95 GGNs, and 82 patients underwent soft HW localization of 88 GGNs. Technical success rates for the conventional and soft HW groups were 96.8% and 100%, respectively (P = 0.25), and the duration of localization was similar in both groups (mean [SD], 10.1 [4.5] vs 10 [5.9] min; P = 0.97). Complications were significantly more common in the conventional HW group than in the soft HW group (48.9% vs 32.9%, respectively; P = 0.04). Visual analog scale scores in the conventional HW group were significantly higher than those observed in the soft HW group (mean [SD], 4.6 [0.6] vs 3.4 [0.6]; P = 0.001). The rates of technical success for limited resection procedures were similar in both groups (96.8% vs 100% in the conventional and soft HW groups, respectively; P >0.99).

CONCLUSIONS

Conventional and soft HW strategies can both effectively facilitate preoperative pulmonary GGN localization, but the soft HW approach has a more favorable safety profile.
