目的探讨CT引导下经皮肺穿刺活检术在肺部占位性病变中的诊断价值。方法 52例肺部占位性病变患者,以随机抽签方式分为研究组及对照组,各26例。研究组采取CT引导下经皮肺穿刺活检术进行诊断,对照组采取超声引导下经皮肺穿刺活检术进行诊断。对比两组患者的一次性定位成功率、一次性活检成功率、并发症发生率及诊断准确率。结果研究组患者一次性定位成功率为92.31%,高于对照组的69.23%,差异具有统计学意义(χ~2=4.457,P=0.035<0.05)。研究组患者一次性活检成功率为100.00%,高于对照组的65.38%,差异具有统计学意义(χ~2=10.884,P=0.000<0.05)。研究组患者并发症发生率为7.69%,低于对照组的30.77%,差异具有统计学意义(χ~2=4.457,P=0.035<0.05)。研究组患者诊断准确率为96.15%,对照组诊断准确率为88.46%,对比差异无统计学意义(χ~2=1.083,P=0.298>0.05)。结论 CT引导下经皮肺穿刺活检术在肺部占位性病变中的诊断价值显著,对于肺部占位性病变的诊断准确性较高,定位准确,且对病灶的活检成功率较高,并发症少,值得推广应用于临床。
Objective To investigate the diagnostic value of CT-guided percutaneous lung biopsy in space-occupying lesions in the lungs. Methods Totally 52 cases of lung space occupying lesions were randomly divided into study group and control group with 26 cases in each group. The study group underwent CT-guided percutaneous lung biopsy for diagnosis, and the control group underwent ultrasound-guided percutaneous lung biopsy for diagnosis. One-time positioning success rate, one-time biopsy success rate, complication rate and diagnostic accuracy were compared between the two groups. Results The success rate of one-time positioning in the study group was 92.31%, which was higher than that in the control group (69.23%). The difference was statistically significant (χ ~ 2 = 4.457, P = 0.035 <0.05). The successful rate of one-off biopsy in the study group was 100.00%, which was higher than 65.38% in the control group (χ ~ 2 = 10.884, P = 0.000 <0.05). The incidence of complication in study group was 7.69%, which was lower than that in control group (30.77%) (χ ~ 2 = 4.457, P = 0.035 <0.05). The diagnostic accuracy of the study group was 96.15%, while that of the control group was 88.46%. There was no significant difference between the two groups (χ ~ 2 = 1.083, P = 0.298> 0.05). Conclusion CT-guided percutaneous lung biopsy has significant diagnostic value in lung space occupying lesions, high diagnostic accuracy for lung space occupying lesions, accurate positioning and high success rate of biopsy of the lesions, Less complications, it is worth to promote the clinical application.
