Abstract
Introduction: Computed tomography (CT)-guided core needle biopsy (CNB) is a common method for diagnosing pulmonary nodules (PNs). It is often performed using the coaxial technique (CAT) to streamline the process.
Aim: This study aimed to compare the safety and diagnostic performance of CT-guided CNB with and without CAT for diagnosing PNs.
Materials and methods: This retrospective analysis included patients undergoing CT-guided CNB for a diagnosis of PNs between January 2017 and December 2019. The study population was divided according to the use of CAT for the biopsy. Procedure-related data, diagnostic accuracy and yield, and complication rates were compared between the 2 groups.
Results: During the study period, a total of 111 and 108 patients underwent CT-guided CNB with and without CAT, respectively. As compared with the non-CAT group, the CAT group showed a lower mean needle pathway number (P <0.001), a higher mean sample number (P <0.001), and shorter procedural duration (P <0.001). Diagnostic accuracy was similar between the 2 groups (98.3% vs 96.3%, respectively, for CAT vs non-CAT; P = 0.6), though the CAT group demonstrated a higher diagnostic yield than the non-CAT group (81.4% vs 68.5%; P = 0.03). Pneumothorax and pulmonary hemorrhage rates did not differ between the 2 groups (P = 0.09 and P = 0.16, respectively).
Conclusions: CT-guided CNB with CAT demonstrated greater procedural efficiency, with fewer needle pathways, shorter operative duration, and improved diagnostic yield, as compared with procedures performed without CAT.
计算机断层扫描(CT)引导下的核心穿刺活检(CNB)是诊断肺结节(PNs)的常用方法。它通常使用同轴技术(CAT)来简化过程。目的:本研究旨在比较ct引导下CNB在有和没有CAT的情况下诊断PNs的安全性和诊断性能。材料和方法:本回顾性分析包括2017年1月至2019年12月期间接受ct引导下CNB诊断PNs的患者。根据使用CAT进行活检来划分研究人群。比较两组手术相关数据、诊断准确性、诊断率和并发症发生率。结果:在研究期间,分别有111例和108例患者接受了ct引导下的CNB伴CAT和不伴CAT。与非CAT组相比,CAT组的平均针路数较低(P P P P = 0.6),尽管CAT组的诊断率高于非CAT组(81.4% vs 68.5%;P = 0.03)。两组间气胸和肺出血发生率无显著差异(P = 0.09和P = 0.16)。结论:与不进行CAT的手术相比,ct引导下的CNB具有更高的手术效率,针头路径更少,手术时间更短,诊断率更高。
