针芯导丝在支气管内超声引导针吸活检术中的应用研究

A comparative study of endobronchial ultrasound guided transbronchial needle aspiration with and without a stylet

目的研究比较在进行经支气管内超声引导针吸活检术(EBUS-TBNA)时,穿刺针内用和不用针芯导丝对诊断效率和病理结果的影响。方法共80例患者分用与不用针芯导丝两组,每组40例患者,进行EBUS-TBNA操作,分析两组诊断准确率和病理标本质量的差别。结果用与不用针芯导丝两组患者的诊断准确率分别是90%(36/40)和85%(34/40),两者比较差异无显著性(P=0.74),细胞学标本合格率比较差异无显著性(P=0.88),组织病理学标本质量比较差异亦无显著性(P=0.57)。用针芯导丝组检查时间为(12.3±2.1)min,不用针芯导丝检查时间为(10.3±1.0)min,两组比较差异有显著性(P<0.05)。结论进行EBUS-TBNA检查时,专用穿刺针内腔不用针芯导丝对诊断效率和标本质量没有影响,但节省了检查时间。

【Objective】To compare the effect of endobronchial ultrasound guided transbronchial needle aspiration（EBUS-TBNA） with and without a stylet for the diagnostic yield and quality of specimens.【Methods】80 patients were divided into two groups（group A, n =40 and group B, n =40）. The patients in group A underwent EBUSTBNA with a stylet and group B underwent EBUS-TBNA without a stylet, the diagnostic accuracy and specimen quality were compared between the two groups. 【Results】The diagnostic accuracy was 90%（36/40） in group with stylet and 85%（34/40） in group without stylet,there was no significant difference（P =0.74）. Moreover, no significant difference was observed either on the adequacy（P =0.88） and quality（P =0.57） of the samples between the two groups. Time spend in group without stylet（10.3±1.0） min was significantly shorter than group with stylet（12.3±2.1）min（P 0.05）. 【Conclusion】In EBUS-TBNA, without the use of the stylet does not decrease the diagnostic yield and quality of specimens, and dose shorten time spending.
