目的探讨麦默通微创旋切系统在临床触诊阴性乳腺良恶性病灶治疗中的应用价值。方法对68例共88处乳腺病灶行麦默通旋切术。结果所有临床触诊阴性病灶均被完整切除；病理提示良性病灶75处，恶性病灶13处，良恶性病灶在患者年龄及病灶数目、性质、边界、回声、分级指数、典型钙化特性方面存显著性差异；非良性病灶行二次手术后病理提示乳腺癌检出灵敏度83-3％（5／6），特异度100％（7／7），假阳性率0（0／7），假阴性率16．7％（1／6）；术后无严重并发症发生，随访患者美观效果满意度96．2％（50／52）。结论麦默通微创旋切系统以便捷、安全、美观等特点成为治疗临床触诊阴性乳腺良性病灶的首选方法，同时对于乳腺良恶性病灶的鉴别有重要指导意义，但对于乳腺非良性病灶需增加旋切次数并行二次手术以降低乳腺癌漏诊率。

英文摘要：

Objective To evaluate the therapeutic value of Mammotome system （UMS） in clinical non-palpable breast lesions. Methods Sixty-eight consecutive females carried out 88 procedures. Results All of breast lesions were resected completely by UMS ;74 benign and 13 non-benign lesions were identified by pathology reviews;while significant differences were found in patients＇ age and characteristics of breast lesions between two groups; pathology reviews of re-operations for non-benign lesions indicated false negative rate for the detection of malignant tumor was 16.7% （1/ 6） ; no severe postoperative complications and high degree of satisfaction were reported in follow-up. Conclusion UMS procedure with characteristics of convenience, safety, aesthetics is recommended for the treatment of clinical non- palpable breast benign lesions as a preferred method, at the same time,it plays an important role in exploring the lesions, however, repeated rotary cuts and reoperations are needed to low the false dismissal rate for the detection of malignant tumor in non-benign lesions.
