    Abstract:
    OBJECTIVE: To compare two kinds of metal markers for preoperative localization of ground glass nodules (GGNs). METHODS: We retrospectively investigated data from 198 cases of GGN localization and compared the success rate and complications of both approaches. RESULTS: In the hook wire and coil groups, the success rates of CT-guided localization for GGNs were 99.2 and 98.7%, respectively (p = 1.000). The success rates of video-assisted thoracoscopic surgery in both groups were 100% without transthoracic surgery. The post-localization complication rates in the hook wire group and coil group were 36.9 and 32.9% (p = 0.568), and the postoperative complication rates in the hook wire and coil groups were 13.9 and 11.8%, respectively (p = 0.672). CONCLUSIONS: Preoperative localization of GGNs with both hook wire and coil methods proved to be useful and effective. Both methods have acceptable preoperative and postoperative complication rates, but the localization and operation times were shorter for the hook wire group than the coil group. ADVANCES IN KNOWLEDGE: Most of previous articles studied a single preoperative localization method. Few studies have compared the preoperative and postoperative methods for metal markers. This paper compared two preoperative localization methods for GGNs to provide clinical guidance.
