目的 :评价经纤维支气管镜肺活检 (TBPB)结合经皮穿刺针吸活检 (PNAB)对肺周围型结节或肿块 (PPN/M)的诊断价值。方法 :128例PPN/M患者 (Ⅰ组 )先行TBPB ,结果阴性者加做PNAB。另60例PPN/M患者 (Ⅱ组 )先做PNAB ,阴性者再做TBPB。结果 :单做TBPB和PNAB的诊断率分别为70 %和85 % ,TBPB结合PNAB的诊断率达95 %。显示两种方法的诊断率均与病灶的大小和部位有关。结论 :TBPB和PNAB对PPN/M都是有价值的诊断手段 ,两种方法有相互补充作用 ,联合使用可明显提高诊断率
Objective: To evaluate the diagnostic value of percutaneous transluminal lung biopsy (PNAB) combined with percutaneous needle biopsy (TBPB) and percutaneous needle biopsy (PPN / M). Methods: 128 cases of PPN / M patients (group Ⅰ) TBPB first, the results were negative plus PNAB. The other 60 cases of PPN / M patients (group Ⅱ) first make PNAB, negative again TBPB. Results: The diagnostic rates of TBPB and PNAB alone were 70% and 85%, respectively, and the diagnostic rates of TBPB and PNAB were 95%. The diagnostic rates of both methods are related to the size and location of the lesion. CONCLUSION: Both TBPB and PNAB are valuable diagnostic tools for PPN / M. The two methods are complementary to each other, and the combined use of TBPB and PNAB can significantly improve the diagnostic rate
