Abstract

Background: With the extensive development of minimally invasive surgery for pulmonary nodules, preoperative localization becomes more and more critical. There are some defects in traditional localization methods, so it is necessary to improve. The aim of this study was to compare and analyze the safety and effectiveness of two new methods, namely four-hook needle and memory alloy coil, in the localization of pulmonary nodules.

Methods: A retrospective analysis of 152 patients was performed. 76 cases were in four-hook needle group, and 76 cases were in memory alloy coil group. Pulmonary nodules were located before operation, and then video-assisted wedge resection was performed. The average procedure time, localization complications and nodule resection time were counted.

Results: The target pulmonary nodules were successfully removed in both groups. In four-hook needle group, 76 patients found localization devices, all the pulmonary nodules were successfully removed, and one case was transferred to open the chest for wedge resection of pulmonary nodules due to severe thoracic adhesion. All 76 patients in memory alloy coil group were successfully resected with pulmonary nodules, and one patient underwent compromising enlarged resection because no lesion was found after the specimen was removed during the operation. There was no significant difference in the incidence of pneumothorax and pulmonary hemorrhage, the success rate of localization and nodule wedge resection time between the two groups. The average time of localization in four-hook needle group was (13.66±3.11) min, lower than that of memory alloy coil group (15.51±3.65) min, and the difference was statistically significant (P=0.001). In memory alloy coil group, when the distance from the nodule to the pleura was ≥1.5 cm and <1.5 cm, the average localization time was (17.20±4.46) min and (14.91±3.15) min, respectively, and there was a statistical difference between the two distance (P=0.044).

Conclusions: Four-hook needle and memory alloy coil have good safety and effectiveness, and the localization time of four-hook needle is shorter. When using memory alloy coil, the effect of the method is better for pulmonary nodules with a distance less than 1.5 cm to pleura.

【中文题目:四钩定位针和记忆合金弹簧圈 在肺结节定位中的应用比较】 【中文摘要:背景与目的 随着肺结节微创手术的广泛开展,术前定位变得愈发关键。传统定位方式存在一定的缺陷,定位方式的改进很有必要。本研究旨在对比分析两种新型定位方式即四钩定位针和记忆合金弹簧圈在肺结节定位中应用的安全性和有效性。方法 回顾性分析152例患者的资料,76例为四钩定位针组,76例为记忆合金弹簧圈组,术前均行肺结节定位,后行电视胸腔镜辅助肺结节楔形切除术,统计平均定位时间、定位并发症、结节切除时间等。结果 两组患者均成功切除目标肺结节,四钩定位针组76例患者术中均找到定位装置,肺结节全部成功切除,1例因严重胸腔粘连而中转开胸行肺结节楔形切除术。记忆合金弹簧圈组76例患者肺结节均成功切除,1例因术中切除标本后未找到病灶而行妥协性扩大切除术。两组气胸、肺内出血发生率、定位成功率、结节楔形切除时间无统计学差异。四钩定位针组平均定位时间为(13.66±3.11)min,低于记忆合金弹簧圈组的(15.51±3.65)min,二者有统计学差异(P=0.001)。记忆合金弹簧圈组当结节至胸膜距离≥1.5 cm和<1.5 cm时,平均定位时间分别为(17.20±4.46)min、(14.91±3.15)min,二者有统计学差异(P=0.044)。结论 四钩定位针和记忆合金弹簧圈两种新型肺结节定位方式均有较好的安全性及有效性,四钩定位针定位操作用时更短。在使用记忆合金弹簧圈定位时,对于到胸膜距离<1.5 cm的肺结节效果可能更佳。 】 【中文关键词:定位;胸腔镜;肺结节】.
