目的探讨肺外周结节两种活检方法的差异。方法对48例肺外周结节行 X-线透视下经支气管肺活检(TBLB)术,与36例肺外周结节行 CT 引导下经皮肺穿刺活检的结果进行比较。结果 TBLB 组的诊断正确率为95.8%,出血发生率81.3%,无气胸发生;CT 引导组的诊断正确率为83.3%,出血发生率8.3%,气胸发生率27.8%。结论对于肺外周结节,X 线透视下 TBLB 术的诊断正确率高于 CT 引导下经皮肺穿刺,气胸的发生率较后者低,出血的发生率较后者高。两种方法均安全可靠。
Objective To investigate the differences of two biopsy methods of peripheral pulmonary nodules. Methods Forty-eight patients with peripheral pulmonary nodules underwent CT-guided percutaneous lung biopsy under X-ray fluoroscopy with bronchoscopic lung biopsy (TBLB) and 36 patients with peripheral pulmonary nodules. Results The diagnostic accuracy rate of TBLB group was 95.8% and the bleeding rate was 81.3%. No pneumothorax occurred in the group of TBLB. The diagnostic accuracy of the CT group was 83.3%, the incidence of bleeding was 8.3% and the incidence of pneumothorax was 27.8%. Conclusion For the peripheral pulmonary nodules, the diagnostic accuracy of TBLB under X-ray is higher than that of CT guided percutaneous lung puncture. The incidence of pneumothorax is lower than that of the latter, and the incidence of hemorrhage is higher than that of the latter. Both methods are safe and reliable.
