Abstract: IntroductionComputed tomography (CT)-guided suture anchor localizer (SAL) placement is increasingly used to facilitate preoperative localization of pulmonary nodules (PNs) before video-assisted thoracoscopic surgery (VATS).Although this approach is well established for single nodules, evidence regarding its application to multiple nodules remains limited.Aim To evaluate the safety and efficacy of CT-guided SAL placement for simultaneous localization of multiple PNs.Materials and methods A two-center retrospective study (January 2023-December 2024) was conducted enrolling patients who underwent CT-guided SAL placement for multiple PNs followed by VATS resection.A contemporaneous cohort undergoing single PN localization served as a comparison group.Clinical outcomes and procedural complications were analyzed between groups.Results Forty-nine patients underwent the localization of 106 PNs in the multiple-nodule group, whereas 163 patients underwent the localization of 163 single PNs in the singlenodule group.The technical success of SAL placement was 100% in both groups.Localization time was significantly longer in the multiple-nodule group (P <0.001).Pneumothorax and intrapulmonary hemorrhage occurred more frequently after multiple SAL placements (36.7% and 28.6%) compared with single-nodule localization (18.9% and 16.0%, P = 0.007 and 0.048, respectively).Despite these differences, the technical success of VATS sublobar resection was 100% in both cohorts.Conclusions CT-guided SAL placement is a reliable and safe method for preoperative localization of multiple PNs, supporting its clinical utility in patients undergoing VATS.
