肺部孤立性结节大小与穿刺活检术的临床研究

【摘要】 目的探讨肺部孤立性结节(solutionpulmonarynodule,SPN)大小与CT导引下经皮穿刺活检术(PercutaneousPunctureBiopsy,PPB)成功率和诊断正确率的关系。方法对41例SPN患者进行CT导引下PPB检查,对比PPB检查与手术病理结果,分析CT导引下PPB检查正确率与SPN大小的关系。结果SPNCT导引下PPB穿中率100%,诊断正确率90.2%,并发症发生率12.2%。SPN直径<2cm诊断正确率78.6%(11/14),直径2~3cm诊断正确率96.3%(26/27)。结论CT导引下PPB检查具有安全、准确、简便等优点,可为临床制定治疗方案提供重要依据。SPN直径<2cm影响CT导引下PPB诊断准确率。更多还原

【Abstract】 Objective To explore clinical application and factors influencing diagnostic accuracy in CT-guided percutaneous puncture biopsy (PPB) of solution pulmonary nodule (SPN). Methods The diagnosis of 41cases with SPN were compared between results PPB and pathological conclusion after surgery of and factors influencing diagnostic accuracy were analysized in CT-guided PPB. Results The puncture accuracy was 100, the diagnostic accuracy was 90.2(37/41), the complication rate was 12.2(5/41)in CT-guided PPB of SPN. The determining factors influencing diagnostic accuracy and complication rate were age of patients, present of emphysema, size and internal content of SPN in CT-guided PPB. Conclusion CT-guided PPB was a safe accurate simple means of diagnosis and differential diagnosis for SPN, providing important information for clinical treatment. Diagnostic accuracy will be influenced by diameter of SPN(D<2cm).更多还原
