麦默通十字交叉法结合平移法旋切较大良性乳腺肿块的可行性研究

目的 探索口径为2.5 cm旋切槽的麦默通旋切系统（mammotome,MMT）,通过十字交叉法结合平移法旋切切除直径3-6 cm较大良性乳腺病灶的可行性.方法 试验组160例,乳腺肿物直径3 -6 cm,麦默通结合高频超声引导,采用十字交叉平移法旋切术.对照组160例,病灶直径＜2.5 cm,接受麦默通常规手术治疗.2组治疗疗效及并发症进行比较,统计学分析采用,检验.结果 手术成功率100％.在术中出血、皮肤瘀斑、术后血肿的发生率方面行x2检验,2组差异均无统计学意义（χ2 =0.251 8,P=0.616;χ2 =0.328 2,P=0.567;χ2=0.146 3,P=0.702）,手术瘢痕外观及并发症方面,2组差异无统计学意义.结论 麦默通十字交叉平移法旋切术切除3-6 cm较大良性乳腺肿块可行,具有安全、微创、美容、并发症少等优点,有一定的应用价值.

Mammotome system in treatment of large benign breast tumor

Objective To explore the possibility of using the mammotome system （MMT） with 2.5 cm spiral cutting mode to resect benign tumor of 3-6 cm in diameter.Methods The study group consisted of 160 patients with tumor of 3-6 cm in diameter,who received treatment of MMT cross combination with parallel rotary cutting method.The control group consisted of 160 patients with tumor 〈 2.5 cm and received routine MMT operation.The therapeutic effects and complications of the two groups were compared.Chi-sqare test was used for statistical analysis.Results All operations were successful on MMT.There was no statistical difference in intraoperative bleeding,skin ecchymosis and postoperative hematomas between the two groups（χ2 =0.251 8,P =0.616;χ2 =0.328 2,P =0.567 ;χ2 =0.146 3,P =0.702）.The hospitalization duration,the operation scar and other complications were similar between the two groups.Conclusions The MMT cross combination with parallel rotary cutting method can be used to resect 3-6 cm benign breast tumors.It has the advantages of safety,efficiency,minimal invasiveness,covertincision,good cosmetic effect and low complications.
