Introduction
Computed tomography (CT)-guided liquid material (LM) and hook-wire (HW) are usually localized for pulmonary nodules (PNs) before video-assisted thoracic surgery (VATS) resection, but the relative advantages of these 2 techniques remain uncertain.

Aim
This meta-analysis was conceived to juxtapose the efficacy and safety of HW localization (HWL) and LM localization (LML), both guided by CT, for the preoperative localization of PNs.

Material and methods
The PubMed, Web of Science, and Wanfang databases were searched to identify relevant studies published as of March 2023, after which pooled analyses of study outcomes were conducted.

Results
A total of 7 studies were included in this meta-analysis from 142 relevant studies. These 7 studies included 551 patients (583 PNs) with CT-guided HWL and 551 patients (612 PNs) with LML. The successful localization rate was significantly higher in the LM group (LMG) than in the HW group (HWG) (p = 0.002). The LMG also exhibited significantly lower pooled total complication and lung haemorrhage rates than the HWG (p = 0.007 and 0.00001, respectively). Pooled localization duration, pneumothorax rates, and VATS procedure duration were comparable in both groups (p = 0.45, 0.15, and 0.74, respectively). Furthermore, the pooled postoperative hospital stay was significantly shorter in the LMG than in the HWG (p = 0.009). Significant heterogeneity was detected in the endpoints of localization duration and pneumothorax rate (I2 = 93% and 66%, respectively).

Conclusions
CT-guided LML is safer and more successful than HWL for patients with PNs before VATS resection.
