摘要
目的 探讨超声引导16 G针和18G针经皮穿刺肺活检(US-PCNB)的临床应用价值,比较两种针型在肺活检术中的取材成功率及安全性.方法 二维超声引导下对79例声像显示清晰的肺肿块患者使用粗针行US-PCNB,其中使用16G针穿刺取材58例,使用18G针穿刺取材21例.结果 使用16G针穿刺取材获取肺病变组织条块较粗大,1～2次进针活检取材的成功率为84.5%(49/58)明显高于使用18G针的成功率38.9%(7/21),两种针型肺活检成功率比较差异有统计学意义(P＜0.01);与18G针比较,16G针穿刺活检并发症的发生率低、安全性好,两种针型穿刺活检的安全性比较差异有统计学意义(P＜0.05).结论 使用16G针能在保证获取足够肺病变标本基础上明显减少进针次数,从而降低了肺穿刺并发症的发生率.
Objective To discuss the clinical value using 16G heavy needle and 18G heavy needle in ultrasonography (US) guided percutaneous needle biopsy (US-PCNB), and to compare the successful rate and safety in PCNB with the two types of the needle. Methods Totally 79 patients were biopsied with heavy needle to get lung tumour samples definitely by Planar-US. In the 79 cases, 58 were biopsied with 16G heavy needle and 21 with 18G heavy needle. Results The pathological tissue samples gained from the lung tumour puncture using 16G heavy needle were thicker, and the successful rate of 84.5% (49/58) only through 1-2 procedures was distinctly higher than that of 38.9% (7/21) using 18G heavy needle. The successful rate of the two needle types were statistically significant(P<0.01). Compared to the 18G heavy needle, the 16G heavy needle had lower complication occurrence and higher safety with statistic significance(P<0.05). Conclusions Results on the basis of 16G heavy needle application, we can get enough tissue biopsy samples so that procedure times will be reduced and complications due to puncture will also be decreased simultaneously.
