Abstract

Background: The possibility of coil dislocation in computed tomography (CT)-guided microcoil localization of superficial pulmonary nodules is relatively high. The aim of the study is to investigate the outcomes of deeper localization technique during CT-guided microcoil localization of superficial pulmonary nodules before video-assisted thoracoscopic surgery (VATS).

Methods: Fifty-seven identified superficial pulmonary nodules (nodule-pleural distance ≤ 1 cm on CT image) from 51 consecutive patients underwent CT-guided microcoil localization, and subsequent VATSs were included. The rate of technical success, complications, and excised lung volume were compared between deeper localization technique group and conventional localization technique group.

Results: The technical success rate of the localization procedure was 100% (25/25) in the deeper localization group and 81.3% (26/32) in the conventional localization group (p = 0.030). Excluding one case of lobectomy, the excised lung volume in the deeper localization group and the conventional localization group was 39.3 ± 23.5 and 37.2 ± 16.2 cm³, respectively (p = 0.684). The incidence of pneumothorax was similar between the deeper localization group and the conventional localization group (24.0 vs. 21.9%, respectively, p = 0.850). The incidence of intrapulmonary hemorrhage in the deeper localization group was higher (16.0%) than that in the conventional localization group (6.3%), but the difference was not statistically significant (p = 0.388).

Conclusion: CT-guided microcoil localization of superficial pulmonary nodules prior to VATS using a deeper localization technique is feasible. Deeper localization technique reduced the occurrence of dislocation but did not increase excised lung volume.

CT引导下肺浅表结节深层定位技术的疗效。

背景：在计算机断层扫描（CT）引导的肺浅表结节微线圈定位中，线圈错位的可能性相对较高。本研究的目的是探讨电视胸腔镜手术（VATS）前CT引导下肺浅表结节微线圈定位过程中深层定位技术的结果。方法： 57个确定的浅表性肺结节（结节胸膜距离≤1 CT图像上的cm）进行CT引导的微线圈定位，并包括随后的VATS。比较深层定位技术组和常规定位技术组的技术成功率、并发症和切除肺容量。结果：深层定位组和常规定位组的技术成功率分别为100%（25/25）和81.3%（26/32）（p = 0.030）。除一例肺叶切除术外，深层定位组和常规定位组的切除肺体积为39.3 ± 23.5和37.2 ± 16.2 cm3（p = 较深定位组和常规定位组的发生率相似（分别为24.0%和21.9%，p = 深定位组肺内出血发生率（16.0%）高于常规定位组（6.3%），但差异无统计学意义（p = 0.388）。结论：在VATS之前，CT引导下的肺浅表结节微线圈定位使用更深的定位技术是可行的。更深入的定位技术减少了脱位的发生，但没有增加切除的肺体积。
