超声与CT引导下经皮肺穿刺活检诊断周围型肺癌的临床应用价值

Clinical value of ultrasound-guided and CT-guided percutaneously transthoracic lung biopsy for peripheral lung cancer

目的探讨超声与CT引导下经皮肺穿刺活检对周围型肺癌诊断的临床应用价值。方法回顾性分析我院经胸部CT疑诊为周围型肺癌,且经超声或CT引导下经皮肺穿刺活检术患者331例,其中超声引导组42例,CT引导组289例。比较两组的肺癌确诊率和并发症发生率。结果超声引导组肺癌确诊率85.71%,CT引导组肺癌确诊率94.12%,两组比较差异无统计学意义（χ^2=4.005,P=0.056）。超声引导组气胸、咯血发生率分别为7.14%、9.52%;CT引导组气胸、咯血发生率分别为4.84%、3.81%,两组并发症发生率比较差异无统计学意义（χ^2=2.698,P=0.156）。结论经超声与CT引导下经皮肺穿刺活检对周围型肺癌患者的诊断均安全、准确。

Objective To investigate the clinical value of ultrasound-guided and CT-guided percutaneously transthoracic lung biopsy for peripheral lung cancer. Methods The clinical characteristics and data of 331 patients with suspected peripheral lung cancer who received ultrasound-guided or CT-guided percutaneously transthoracic lung biopsy were retrospectively analyzed. These patients were divided into ultrasound-guided group（42 cases）and CT-guided group（289 cases）.The accuracy of diagnosis and the incidences of complications were comparatively analyzed. Results The accuracy of diagnosis was 85.71% for ultrasound-guided group,and 94.12% for CT-guided group,there was no significance difference between two groups（χ~2=4.005,P=0.056）. The incidences of pneumothorax and hemopytsis were 7.14% and 9.52% in ultrasound-guided group,respectively. The incidences of pneumothorax and hemopytsis were 4.84% and 3.81% in CT-guided group,respectively,there was no significance difference between two groups（χ~2=2.698,P=0.156）. Conclusion Both ultrasound-guided and CTguided percutaneously transthoracic lung biopsies are minimally invasive,safe and accurate diagnostic procedure for peripheral lung cancer.
