摘　　要：目的 采用双针穿刺法提高肺小结节(≤2 cm)CT引导经皮穿刺活检的一针穿刺成功率,并降低并发症。方法 对65例肺内小结节患者随机分为A、B两组,分别采用双针穿刺法及传统穿刺法,使用卡方检验对其一针成功率及并发症分别比较。结果 A、B两组的一次穿刺成功率分别为90.9%和50.0%(χ~2=11.24,P=0.000 8);并发症的发生率分别为18.2%和59.4%(χ~2=9.97,P=0.001 6),存在差异且具有统计学意义(P<0.05)。结论 双针穿刺法可以明显提高一针穿刺成功率,降低并发症的发生率,从而缩短穿刺时间及X线下的暴露时间。Objective To use double-needle puncture technique to perform CT-guided percutaneous puncture biopsy in order to improve the success rate of first puncturing for small pulmonary nodules （less than 2cm） and to reduce the incidence of complications. Methods A total of 65 patients with small pulmonary nodules were randomly divided into group A and group B. Double-needle puncture technique and traditional puncture technique were employed for the patients of group A and group B respectively. By using chi square test, the success rate of first puncturing and the incidence of complications were compared between the two groups. Results In group A and group B, the success rates of first puncturing were 90.91% and 50.00% respectively （χ^2=11.24, P=-0.000 8）, and the incidences of complications were 18.2% and 59.4% respectively （χ^2=9.97, P=0.001 6）; the differences between the two groups were statistically significant （P〈0.05）. Conclusion The double- needle puncture technique can significantly improve the success rate of first puncturing and reduce the incidence of complications, thereby, shortening the time used for puncturing as well as the X-ray exposure time.
