We sought to introduce a localization procedure (methylene blue-stained N-butyl cyanoacrylate and N-octyl cyanoacrylate glue) in localizing pulmonary small nodules and ground-glass opacities before thoracoscopic resection, and to evaluate its efficacy.
A total of 20 patients with pulmonary small nodules and/or ground-glass opacities, who underwent video-assisted thoracoscopic surgery from August 1, 2017 to March 1 2018, were included in the study.
A total of 24 lesions in 20 patients underwent blue-stained glue localization. The success rate of localization was 100%, with a mean dose of 0.04±0.01 mL blue dye and 1 mL glue used for each lesion. The average time for the whole localization procedure was 15.4±6.3 minutes. All lesions were intraoperatively localized by visual inspection in combination with palpation. The complications related to the localization procedure included mild pneumothorax occurring in 9 patients and minor pulmonary hematoma in 4 patients. No pain or distress was reported.
Blue-stained glue injection is technically feasible and safe to localize pulmonary small nodules and ground-glass opacities before thoracoscopic resection.
我们旨在介绍一种定位方法（亚甲蓝染色的正丁基氰基丙烯酸酯和正辛基氰基丙烯酸酯胶），用于在胸腔镜切除前定位肺部小结节和磨玻璃影，并评估其疗效。
2017 年 8 月 1 日至 2018 年 3 月 1 日，共 20 例肺部小结节和/或磨玻璃影患者接受了电视辅助胸腔镜手术，纳入本研究。
20 例患者的 24 个病灶进行了蓝染胶定位。定位成功率为 100%，每个病灶使用的蓝染剂量平均为 0.04±0.01ml，胶用量为 1ml。整个定位过程的平均时间为 15.4±6.3 分钟。所有病灶均通过术中肉眼观察结合触诊进行了定位。与定位过程相关的并发症包括 9 例轻度气胸和 4 例轻微肺血肿。无疼痛或不适报告。
蓝染胶注射是一种技术可行且安全的方法，可用于在胸腔镜切除前定位肺部小结节和磨玻璃影。
