INTRODUCTION: The aim of this study was to evaluate the efficacy of the 4-hook needle localization for pulmonary ground glass nodules (GGNs).
METHODS: From November 1, 2021, to May 31, 2024, 194 patients were diagnosed with one or more GGNs by computed tomography (CT) scan and underwent preoperative CT-guided 4-hook needle localization followed by video-assisted thoracoscope surgery (VATS) wedge resection, segmentectomy or lobectomy. There were 226 nodules in all patients. We analyzed the 4-hook needle localization safety, complications, safe margin and localization depth.
RESULTS: The 4-hook needle localizations success rate was 100% and didn't take place in displacement and dislodgment. The tumor margin distance is about 5-20 mm and all tumor margin was negative thorough final pathology result. 9 patients occurred small parenchymal hemorrhage, 13 patients occurred small pneumothorax and 8 patients occurred small hemoptysis, those complications needn't intervene or tackle and didn't affect surgery. Compared upper and middle lobe to lower lobe, localization time was 13.92 ± 4.6 min vs 13.66 ± 4.28 min respectively, p = 0.69, there was no significant statistical difference. Localization depth was 18.63 ± 7.8 mm vs 15.87 ± 8.52 mm respectively, p = 0.02, there were statistical differences, but the margin tumor distance was 5.16 ± 4.94 mm vs 4.93 ± 3.64 mm, p = 0.73 respectively, there was no statistical difference.
CONCLUSIONS: Preoperative 4-hook needle localization is safe and feasible for GGNs. Guided by 4-hook needle localization, wedge resection can ensure enough safe margins and patient was well tolerated.
