【摘要】 目的 探讨多层螺旋CT导向下,应用BARD活检枪及不同型号活检针经皮肺穿刺活检的临床应用价值。方法 对比分析应用16 G、18 G及20 G活检针3组患者阳性诊断符合率及并发症的发生率。结果 3组阳性诊断符合率分别为16 G组96.4%、18 G组94.4%、20 G组91.7%,假阴性率16 G组3.6%,18 G组5.6%,20 G组8.3%,气胸并发症发生率16 G组26.7%,18 G组7.7%,20 G组5.1%,肺出血发生率16 G组16.7%,18 G组5.1%,20 G组2.6%。3组阳性诊断符合率及假阴性率无统计学意义。并发症的发生率3组比较差异有统计学意义,16 G组气胸肺压缩及肺出血的严重程度均高于18 G组和20 G组。结论紧靠胸膜的较大肿块可选用16 G针,穿刺针道区肺功能结构正常者多选用18 G针,对病灶较小、位置较深和/或有轻度肺气肿者宜选用20 G针。更多还原

【Abstract】 Objective To evaluate the clinical application with different model needles in percutaneous lung biopsy under multislice spiral CT-guided using BARD gun.Methods Percutaneous lung biopsies were performed using 16G,18G and 20G needles in108 cases,respectively,the diagnostic efficacy and complications were comparatively analysed.Results The diagnostic accurate rates were 96.4%,94.4% and 91.7% with 16G,18G and 20G,respectively.False negative rates were 3.6%,5.6% and 8.3 %,pneumothorax presented rates were 26.7%,7.7% and 5.1%,pneumorrhagia presented rates were 16.7%,5.1% and 2.6% with 16G,18G and 20G,respectively.The diagnostic accuracy and false negative rates are not of statistically significant between 16G,18G and 20G.The incidence of complications in 16G group is higher compared with that in 18G and 20G group which is of statistical significance.Conclusion In general,16G,18G and 20G should be chosen for the lung lesions near to pleural larger bump,patients with normal lung function,and smaller with deep position or with mild emphysema,respectively.更多还原
