麦默通微创旋切术治疗乳腺较大肿块的临床研究

Clinical research of the bigger breast tumor operated by Mammotome system

目的研究超声引导下手助麦默通（Mammotome）微创旋切术对较大乳腺肿块的治疗效果。方法对100例直径为2．5—6．0cm的乳腺肿块（试验组）进行超声引导下手助Mammotome微创旋切术，与传统开放手术100例（对照组）进行疗效比较。结果试验组经Mammotome微创旋切术切除，平均旋切25次，平均用时（20±10）min，无一例操作失败。术后5例（5％）有轻度皮下淤血，2例（2％）压迫松动致创道出血，无切口感染等其他并发症发生。两组在手术时间、出血量、切口愈合时间及术后外观方面比较差异均有统计学意义（P均〈0．05）。结论Mammotome微创旋切术在手助和超声引导下能很好地进行乳腺纤维腺瘤等较大乳腺肿块的微创切除术。该手术安全、高效，在切除病灶的同时兼具微创和美容效果。

Objective To study the diagnostic and therapeutic effect of Mammotome system with hand help introduced by type-B ultrasonic on the bigger breast tumor. Methods Two hundred patients suffered from breast tumor with the diameter ranged from 2.5 to 6.0 cm were selected and divided into two groups with the equal amount. The experimental group（n = 100） was exposed to the treatment with the Mammotome system with hand help introduced by type-B ultrasonic, and the control group （n = 100） was subjected to the traditional opening operation. The curative effect was evaluated respectively. Results The average rotary was 25 times and the duration was （20±10）minutes. There was little tissue trauma and the skin incision was also small. It happened no other complications exception of 5 cases＇ mild ecchymoma and 2 cases＇ wound tract bleeding in the experimental group. The difference was statistically significant between the two groups regarding the operation duration, the amount of bleeding, the incision healing and the postoperative appearanee（P 〈 0.05）. Conclusions Mammotome system with hand help introduced by type-B ultrasonic might be suitable for the mierotmuma excision or sample acquisition of the bigger tumor such as breast fibroadenoma and so on. This operation is safe. It might bring the simultaneous mierotrauma and cosmetic effect while applied to the tumor excision.
