目的探讨肺部肿块CT导引下经皮穿刺活检术(percutaneouspuncturebiopsy,PPB)的临床应用价值和影响其诊断正确率的相关因素。方法对72例肺部肿块患者进行CT导引下PPB检查,对比PPB结果与临床影像学诊断以及手术病理结论,并进一步分析影响CT导引下PPB诊断正确率的相关因素。结果肺部肿块CT导引下PPB的穿中率为100%,诊断正确率为89.6%(61/72),并发症发生率为11.1%(8/72)。患者年龄,有无肺气肿,肺部肿块的大小、肿块内部组分为影响肺部肿块CT导引下PPB正确率和引起有关并发症的主要因素。结论CT导引下PPB在肺部肿块的诊断和鉴别诊断中具有安全、准确、简便等优点。为提高PPB的正确率和减少并发症的发生,应注意患者、病灶和操作过程中的相关因素。
Objective To investigate the clinical value of CT guided percutaneous puncture biopsy (PPB) in lung masses and the related factors that affect the diagnostic accuracy. Methods 72 patients with pulmonary masses underwent CT-guided PPB examination. The results of PPB were compared with clinical imaging diagnosis and pathological findings. The related factors influencing the diagnostic accuracy of PPB under CT guidance were further analyzed. Results The rate of PPB was 100%. The diagnostic accuracy was 89.6% (61/72) and the complication rate was 11.1% (8/72). Patient age, with or without emphysema, the size of the lung mass, and the internal components of the mass were the main factors influencing the correct rate of PPB and the related complications caused by the CT guided pulmonary mass. Conclusion CT guided PPB has the advantages of safety, accuracy and convenience in the diagnosis and differential diagnosis of pulmonary masses. To improve the accuracy of PPB and reduce the incidence of complications, attention should be paid to patients, lesions and related factors during operation.
