目的 探讨Mammotome手术残腔内灌注生理盐水发现乳腺肿物残留病灶的可行性及应用价值.方法 108例术前诊断为乳腺良性肿物的患者在超声引导下行Mammotome手术,肿物旋切完毕后,往残腔内灌注生理盐水,发现可疑残留病灶后切除并单独送检病理.结果 108例患者共切除246个乳腺肿块,往手术残腔内灌注生理盐水后共发现了可疑残留病灶29个,病理证实残留25个.术后3个月、6个月后超声复查,手术区域均未发现复发病例.该方式使Mammotome手术肿块完全切除率由89.8％0增加到100％.结论 Mammotome手术残腔灌注生理盐水有助于发现残留病灶,引导肿块彻底切除.%Objective To discuss the feasibility and value of NS cavity perfusion in detecting residual breast lesions after Mammotome excision. Methods Breast cavities in 108 patitents were filled with NS after Mammotome excision guided by ultrasound. Further ultrasound examination were performed soon after the perfusion in order to detect possible residual lesions. All suspicious residuals were then removed by mammotome device and the specimen were delivered to pathologist separately. Results Totally, 246 breast masses were removed by US guided mammotome surgery. 25 cases pathologically confirmed residuals among 29 suspicious residuals were detected through NS perfusion procedure among 246 cavities. No recurrence is found by ultrasound examination during every 3-6 months' follow-up. NS perfusion method can help the complete resection rate increase from 89. 8% to 100%. Conclusions NS cavity perfusion is an excellent method in detecting residual breast neoplasms after Mammotome excision. It can then help surgeon completely resect target breast lesions by Mammotome excision system.
