摘　　要：目的:分析CT引导下穿刺活检对不同大小孤立肺结节灶的诊断结果.方法:选择2013年12月至2018年12月我院收治的孤立肺结节患者108例,根据病灶大小分组,>2cm者为A组(n=58),≤2cm者为B组(n=50).两组均行析CT引导下穿刺活检,对比两组患者穿刺活检结果、手术病理结果及并发症情况.结果:A组穿刺一次成功率93.10%显著高于B组80.00%,A组穿刺次数(1.07±0.25)显著少于B组(1.20±0.38),差异有统计学意义(χ2=4.086,t=2.126,P<0.05);A组诊断准确率89.66%显著高于B组74.00%,差异有统计学意义(χ2=4.539,P<0.05);A组并发症发生率13.79%显著低于B组30.00%,差异有统计学意义(χ2=4.208,P<0.05).结论:CT引导下穿刺活检可准确鉴别孤立肺结节的良恶性.但对于病灶大小≤2cm的孤立肺结节具穿刺成功率低、病理诊断准确率低及并发症多的特点,仍存在一定风险.Objective:To analyze the diagnostic results of CT-guided needle biopsy for solitary pulmonary nodules of different sizes.Methods:A total of 108 patients with solitary pulmonary nodules admitted to our hospital from December 2013 to December 2018 were selected and grouped according to the size of lesions.The patients with size>2 cm were set as group A(n=58),and those with size≤2 cm were set as group B(n=50).CT-guided needle biopsy was performed in the two groups.The needle biopsy results,surgical pathological results and complications were compared between the two groups.Results:The success rate of one-time puncture in group A was significantly higher than that in group B(93.10%vs 80.00%)(χ2=4.086,P<0.05).The accuracy rate of diagnosis in group A was significantly higher than that in group B(89.66%vs 74.00%),the puncture frequency in group A was significantly lower than that in group B[(1.07±0.25)vs(1.20±0.38)].(χ2=4.539,t=2.126,P<0.05).The incidence rate of complications in group A was significantly lower than that in group B(13.79%vs 30.00%)(χ2=4.208,P<0.05).Conclusion:CT-guided needle biopsy is a simple and reliable technique,and it can accurately identify the benign and malignant solitary pulmonary nodules.However,it has low success rate of puncture,low accuracy rate of pathological diagnosis and many complications on solitary pulmonary nodules with lesion size≤2cm,and there is still a certain risk.
