隐匿性乳腺肿块术前超声引导定位的临床研究

Clinical study on ultrasound-guided location of occult breast neoplasm before surgery

目的:比较隐匿性乳腺肿物手术前B超引导金属导丝定位活检和直接手术活检在术中出血、手术时间、切除标本大小方面的差别。方法:A组(手术前B超引导金属导丝定位活检组)63例患者中有68个肿物术前用探头频率为7.5～10 MHz飞利浦IE33彩色超声诊断仪引导,美国巴德金属导丝定位后手术活检。B组(直接手术活检组)31例32个肿物直接手术活检。结果:两组发现肿物时间,肿物大小比较,差异无统计学意义(P>0.05)。A组与B组比较,术中出血量明显减少(P<0.05),手术时间明显缩短(P<0.05),切除标本明显缩小(P<0.05),两组差异有统计学意义。结论:超声引导金属导丝定位手术切除乳腺隐匿性肿物具有定位准确、可靠、创伤小、操作简单等优点,明显优于直接手术活检,值得临床推广。

Objective：To compare the differences of blood loss during operation,operation time and the size of removed samples of ultrasound-guided wire location and biopsy（group A）,direct surgical biopsy（group B） before surgery in patients with occult breast neoplasm. Methods：68 neoplasms from 63 patients in group A received biopsy by wire location under the guidance of Philips IE33 color Doppler ultrasonic diagnostic apparatus.32 neoplasms from 31 patients in group B received direct surgical biopsy. Results：There was no significant difference in discovery time and size of neoplasms between the two groups（P〉0.05）.Compared with group B,the amount of blood loss during operation decreased significantly（P〈0.05）,the operation time shortened significantly（P〈0.05）,the size of removed samples decreased significantly（P〈0.05）,there was significant difference in the above-mentioned indexes between the two groups. Conclusion：Ultrasound-guided wire location surgery is accurate,reliable,minimal wound and simple in excision of occult breast neoplasm,and it is superior to direct surgical biopsy,which is worthy to be popularized
