目的评价CT引导下经皮肺穿刺活检对肺部疾病的诊断价值及并发症。方法在CT引导下使用全自动切割针对76例肺部局限性病灶(局限性病灶组——A组)和7例肺部弥漫性病灶(弥漫性病灶组——B组)行经皮肺穿刺活检;分析其穿刺成功率及病理学资料;观察气胸和咯血的发生。结果穿刺物病理学资料显示,2组共有79例成功穿刺活检到病灶组织;肺穿刺成功率。A组穿刺成功率(98.7%)高于B组(57.1%)(P<0.01)。A组肺癌占76.3%(58/75);B组肺癌占28.6%(2/7);二组差异有统计学意义(P<0.01)。合计两组肺部病灶临床总确诊率为95.2%(79/83)。两组合计发生气胸23例;咯血17例。结论CT引导下经皮肺穿刺活检操作简单、可靠,组织学标本获取率及病理学诊断率高,但气胸、咯血等并发症发生的风险仍存在。
Objective To evaluate the diagnostic value and complications of lung cancer by CT guided percutaneous lung biopsy. Methods Percutaneous pulmonary biopsy was performed in 76 patients with focal pulmonary lesions (group A) and 7 patients with diffuse lung mass (group B - diffuse lesions) under automatic CT guidance. ; Analysis of the puncture success rate and pathological data; observe the occurrence of pneumothorax and hemoptysis. Results The pathological data of the puncture showed that there were 79 cases of successful biopsy in the two groups to the lesion tissue; the success rate of lung puncture. The success rate of puncture in group A (98.7%) was higher than that in group B (57.1%) (P <0.01). A group of lung cancer accounted for 76.3% (58/75); B group of lung cancer accounted for 28.6% (2/7); the difference between the two groups was statistically significant (P <0.01). Total clinical diagnosis of lung lesions in both groups was 95.2% (79/83). 23 cases of pneumothorax occurred in two groups; 17 cases of hemoptysis. Conclusion CT-guided percutaneous pulmonary biopsy is simple, reliable, histological specimens and pathological diagnosis rate, but the risk of complications such as pneumothorax, hemoptysis still exist.
