目的 ·观察超声引导下Mammotome微创旋切术在乳腺肿块切除中的应用效果。方法 · 2013年1—12月上海交通大学医学院附属国际和平妇幼保健院乳腺科对1 034例患者1 347处乳腺肿块病灶进行B超引导下Mammotome微创旋切术，通过病理学检查和随访评价诊疗效果。结果 ·所有病灶均成功切除。切除肿块直径0.8～2.4 cm，单肿块平均切除时间10 min（2～20 min），单肿块平均切除组织条数15条，皮肤切口长度0.3～0.5 cm。无严重并发症发生。术后病理学检查示乳腺癌15处（1.11%）。结论 ·超声引导下Mammotome微创旋切术可完整切除乳腺良性肿瘤，有助乳腺恶性肿瘤早期诊断，具有活检病理准确、手术创伤小、手术时间短、术后并发症少等优点。

 Objective · To observe the effects of ultrasound-guided Mammotome procedure on the treatment of breast lumps. Methods · 1 034 patients (1 347 mammary focuses) underwent ultrasound-guided Mammotome procedure in the Department of Breast Disease at the International Peace Maternity & Child Health Hospital affiliated to Shanghai Jiao Tong University School of Medicine in 2013. The effects of ultrasound-guided Mammotome procedure on the diagnosis and treatment of mammary lumps were evaluated via pathological examinations and follow-up visits. Results · All focuses were successfully resected. The diameters of lumps ranged between 0.8 and 2.4 cm with the mean time of 10 min (2-20 min) and the average resected tissue strip number of 15 for resecting a single lump and the skin wound length of 0.3-0.5 cm. There were no serious complications. Postoperative pathological examinations suggested 15 (1.11%) cases of breast cancer. Conclusion · Ultrasound-guided Mammotome procedure can completely resect benign breast tumors and facilitates the early diagnosis of malignant breast tumors with accurate biopsy findings, small wound, short operation duration, and less postoperative complications.
