| Sumario: | Background: A recent increase in the incidental detection of ground glass nodules
(GGNs) has created a need for improved diagnostic accuracy in screening for malignancies.
However, surgical diagnosis remains challenging, especially via video-assisted thoracoscopic
surgery (VATS). Herein, we present the efficacy of a novel electrical navigation
system for perioperative percutaneous transthoracic nodule localization.
Methods: Eighteen patients with GGNs who underwent electromagnetic navigated
percutaneous transthoracic needle localization (ETTNL), followed by 1-stage diagnostic
wedge resections via VATS between January and December 2020, were included in the
analysis. Data on patient characteristics, nodules, procedures, and pathological diagnoses
were collected and retrospectively reviewed.
Results: Of the 18 nodules, 17 were successfully localized. Nine nodules were pure GGNs,
and the remaining 9 were part-solid GGNs. The median nodule size was 9.0 mm (range,
4.0–20.0 mm); and the median depth from the visceral pleura was 5.2 mm (range, 0.0–14.4
mm). The median procedure time was 10 minutes (range, 7–20 minutes). The final pathologic
results showed benign lesions in 3 cases and malignant lesions in 15 cases.
Conclusion: Perioperative ETTNL appears to be an effective method for the localization
of GGNs, providing guidance for a 1-stage VATS procedure. |
