Abstract

Background: Accurate localization of small pulmonary nodules (SPNs) during video-assisted thoracoscopic surgery (VATS) is challenging due to the small size and deep location. Both the 4-hook wire technique and methylene blue are significant methods for preoperative localization of SPNs. This study aimed to compare the safety of both methods by monitoring and recording any surgery-related complications. Additionally, the effectiveness of both methods was compared by measuring the success rate of localization and the time required for both localization and resection of the nodules.

Methods: Patients who underwent computed tomography (CT)-guided lung nodule localization before VATS from May 2021 to April 2023 at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College were analyzed retrospectively. A total of 75 patients with 84 SPNs were included in this study, comprising 35 4-hook anchor patients with 41 SPNs and 40 methylene blue-marked patients with 43 SPNs.

Results: The VATS operative time for SPNs in the 4-hook anchor device group was significantly shorter than that in the methylene blue group (57.4±12.4 vs. 79.5±14.3 minutes; P<0.001). The overall puncture operation time [15.0 (13.0, 16.5) vs. 16.00 (13.8, 21.0); P=0.007] was also significantly different between the 4-hook anchor device group and the methylene blue group. There were no significant differences in localizer depth from the pleura, complications, localization success, hemorrhage, hospital stay, or hospital cost between the two groups (all P>0.05).

Conclusions: Compared with the methylene blue technique, the 4-hook anchor device is safe and reliable and offers a shorter VATS operative time.

四钩锚钉与亚甲基蓝在术前肺结节定位中的比较研究。
背景:在电视胸腔镜手术(VATS)中,小肺结节(SPNs)由于体积小、位置深而具有挑战性。4钩丝技术和亚甲基蓝技术都是术前定位spn的重要方法。本研究旨在通过监测和记录任何手术相关并发症来比较两种方法的安全性。此外,通过测量定位成功率以及定位和切除结节所需的时间来比较两种方法的有效性。方法:回顾性分析中国医学科学院肿瘤医院、北京协和医学院于2021年5月至2023年4月在VATS术前行CT引导下肺结节定位的患者。本研究共纳入75例患者84个spn,包括35例4钩锚患者41个spn和40例亚甲基蓝标记患者43个spn。结果:4钩锚钉组SPNs的VATS手术时间明显短于亚甲基蓝组(57.4±12.4 vs. 79.5±14.3 min;pv . 16.00 (13.8, 21.0);P=0.007] 4钩锚定装置组与亚甲基蓝组间差异也有统计学意义。两组在定位器距胸膜深度、并发症、定位成功率、出血、住院时间、住院费用等方面均无显著差异(P < 0.05)。结论:与亚甲基蓝技术相比,4钩锚定装置安全可靠,可缩短VATS手术时间。
