摘　　要：目的探讨X线引导的二维钩丝定位改良术在乳腺微钙化病灶术前定位中的价值。方法回顾性分析2017年1月至2021年12月于我院行乳腺切除术的76名乳腺癌患者的临床资料,根据手术前钼靶定位方式的不同将其分为试验组和对照组,比较两组患者术前定位时间、术前定位准确性、手术时间及术中出血量的差异。结果38例患者于手术前接受二维钩丝定位改良术,另38例患者于手术前接受传统二维钩丝定位术。试验组术前定位时间为10~27(19.18±4.32)min,对照组术前定位时间为9~22(14.95±2.77)min,两组间比较差异具有统计学意义(P<0.001);试验组定位准确率为92.1%(35/38),对照组定位准确率为68.4%(26/38),两组间差异有统计学意义(P=0.019);对照组手术所用时间(104.37±20.61)min多于试验组(74.68±13.25)min,差异有统计学意义(P<0.001);两组间术中出血量比较,差异无统计学意义(P=0.816)。结论X线引导的二维钩丝定位改良术在乳腺微钙化病灶术前定位方面具有一定价值,为术中准确切除病灶提供了重要参考。Objective To evaluate the value of X-ray guided two-dimensional hook wire localization in preoperative localization of breast microcalcification lesions.Methods The clinical data of 76 breast cancer patients who underwent mastectomy in our hospital from January 2017 to December 2021 were retrospectively analyzed,and they were divided into a test group and a control group according to the different preoperative mammography positioning methods.And the differences in preoperative positioning time,preoperative positioning accuracy,operative time and intraoperative bleeding between the two groups were compared.Results A total of 38 patients underwent modified two-dimensional hookwire positioning before surgery,and the other 38 patients underwent conventional two-dimensional hookwire positioning before surgery.The preoperative positioning time was 10-27(19.18±4.32)min in the test group and 9-22(14.95±2.77)min in the control group,with a statistically significant difference between the two groups(P<0.001).The positioning accuracy rate was 92.1%(35/38)in the test group and 68.4%(26/38)in the control group,and the difference between the two groups was statistically significant(P=0.019).The time spent for surgery in the control group(104.37±20.61)min was more than that in the test group(74.68±13.25)min,and the difference was statistically significant(P<0.001).The difference in intraoperative bleeding between the two groups was not statistically significant(P=0.816).Conclusion X-ray guided two-dimensional hookwire localization modification is valuable in preoperative localization of breast microcalcifications lesions and provides an important reference for accurate intraoperative excision of lesions.
