Modified Microcoil for Preoperative Localization of Solitary Pulmonary Nodules : A Prospective, Single-Arm, Multicenter Clinical Study
Copyright © 2021. Published by Elsevier Inc..
PURPOSE: To evaluate the efficacy and safety of placement of a modified microcoil for precise preoperative localization of solitary pulmonary nodules (SPNs) before video-assisted thoracoscopic surgery (VATS).
MATERIALS AND METHODS: This prospective, single-arm, multicenter study included patients who underwent computed tomography (CT)-guided modified microcoil insertion prior to SPN resection by VATS between January 2018 and June 2018. The patient demographics, nodule characteristics, and histopathologic findings were recorded. The primary endpoints included efficacy and safety.
RESULTS: A total of 96 patients (41 men and 55 women; mean age, 59.3 years ± 8.9) with 96 SPNs were eligible for enrolment in the study. The mean maximal transverse diameter of the nodules was 10.3 mm ± 5.2 (range, 8-20 mm). The mean time between CT-guided microcoil insertion and the start of the surgical procedure was 14.6 hours (range, 12-24 hours). The duration of the preoperative CT-guided microcoil localization procedure was 29 minutes ± 9 (range, 10-35 minutes), and the intraoperative fluoroscopy time was 0.7 minutes ± 0.7 (range, 0.5-3 minutes). The clinical success rate was 96.9% (93/96), and all nodules were successfully resected using VATS. One patient experienced asymptomatic pneumothorax, but there were no cases of pulmonary hemorrhage.
CONCLUSIONS: SPN localization with the modified microcoil is feasible and safe. The modified microcoil can facilitate the thoracoscopic resection of SPNs.
