Summary

Computed tomography (CT)-guided suture anchor localizer (SAL) placement is safe and effective for locating multiple pulmonary nodules (PNs) before surgery. This technique supports successful video-assisted thoracoscopic surgery (VATS) for patients with multiple PNs.

Area of Science:

  • Thoracic Surgery
  • Medical Imaging
  • Interventional Radiology

Background:

  • Computed tomography (CT)-guided suture anchor localizer (SAL) placement is a common method for preoperative localization of pulmonary nodules (PNs) before video-assisted thoracoscopic surgery (VATS).
  • Limited evidence exists for the application of SAL placement in cases involving multiple PNs.

Purpose of the Study:

  • To evaluate the safety and efficacy of CT-guided SAL placement for the simultaneous localization of multiple PNs.
  • To compare outcomes between multiple PN localization and single PN localization.

Main Methods:

  • A retrospective, 2-center study included patients undergoing CT-guided SAL placement for multiple PNs followed by VATS resection.
  • A control group of patients with single PN localization was used for comparison.
  • Clinical outcomes and procedural complications were analyzed.

Main Results:

  • Technical success for SAL placement was 100% in both multiple (106 PNs in 49 patients) and single (163 PNs in 163 patients) nodule groups.
  • Localization time was significantly longer for multiple PNs.
  • Pneumothorax and intrapulmonary hemorrhage rates were higher in the multiple-PN group but VATS sublobar resection success remained 100% in both groups.

Conclusions:

  • CT-guided SAL placement is a reliable and safe method for preoperative localization of multiple PNs.
  • The findings support the clinical utility of this technique for patients undergoing VATS for multiple pulmonary nodules.
