X线引导下乳腺二维与三维导丝定位活检技术的比较

目的评价X线引导下乳腺二维和三维导丝定位活检术（WLBB）的准确性、患者舒适度和不良反应。方法收集乳腺摄影发现临床不可触及的乳腺病变患者71例,其中29例接受X线引导二维WLBB,42例接受X线引导三维WLBB;分别测量导丝分叉点到病灶中心点的距离,同时对患者舒适度进行评分,并统计不良反应发生率。结果三维WLBB导丝分叉点到病灶中心点距离为（5.1±1.3）mm,小于二维WLBB（7.6±1.7）mm,P〈0.001];在患者舒适度评分方面三维WLBB优于二维WLBB（P〈0.05）;二维、三维WLBB不良反应发生率差异无统计学意义（P〉0.05）。结论三维WLBB的准确性、舒适度优于二维,二者不良反应发生率无差异。

Comparison of two-dimensional and three-dimensional X-ray guided wire localization breast biopsy

Objective To compare the accuracy of puncture, degree of comfort and adverse reaction of X-ray guided two-dimensional (2D) and three-dimensional (3D) wire localization breast biopsy (WLBB). Methods All 71 patients with nonpalpable breast lesion detected by mammography were enrolled, 29 underwent X-ray guided 2D WLBB, the others underwent X-ray guided 3D WLBB. The distance from bifurcation of wire to lesion center was measured, the degree of comfort and adverse reaction was reported and recorded, and then were statistically analyzed. Results The distance from bifurcation of wire to lesion of 3D technique ( mm) was shorter than that of 2D technique ( mm, P<0.001). Patients underwent 3D WLBB felt more comfortable than those underwent 2D WLBB (P<0.05). No significant difference of adverse reaction was found between 2D and 3D WLBB (P>0.05). Conclusion The accuracy of puncture and degree of comfort of 3D WLBB is better than those of 2D, and both methods have no difference in adverse reaction.
