目的：探讨超声引导下麦默通旋切术切除乳腺较大良性肿块的可行性与效果。方法：回顾性分析105 例单发的良性肿块（>3.0 cm）行手术治疗患者的临床资料，其中68 例超声引导下麦默通旋切手术（观察组），37 例行传统开放手术（对照组），比较两组的相关手术指标。结果：两组患者年龄、疾病构成、肿瘤大小等基本资料差异无统计学意义（均P>0.05），有可比性。两组的手术时间、术中出血量及术后并发症发生率差异均无统计学意义（均P>0.05），但观察组的切口长度明显小于对照组[（0.53±0.04 ）cm vs. (3.65±0.46) cm，P<0.05]。两组随访1~12 个月，均无肿瘤复发，对照组留有长短不等的瘢痕，而观察组瘢痕微小或不可见。结论：超声引导下麦默通旋切术切除直径>3.0 cm 良性乳腺肿块安全可行，美容效果好，在临床上有应用价值。
Resection of large benign breast tumor with ultrasound-guided Mammotome revolve device
Objective: To investigate the feasibility and effect of resection of large benign breast tumor with an ultrasoundguided Mammotome revolve device. Methods: The clinical data of 105 patients with single breast mass (>3.0 cm) undergoing surgical treatment were retrospectively analyzed. Of the patients, 68 cases underwent ultrasound-guided Mammotome procedure (observational group), and the other 37 cases underwent traditional open surgery (controlled group). The main surgical variables between the two groups were compared. Results: There was no difference between the two groups in the baseline data such as age, disease constitution and tumor size (all P>0.05), so they were comparable. The operative time, intraoperative blood loss and incidence of postoperative complications showed no significant difference between the two groups (P>0.05), but the length of the incisions in observational group was significantly less than that in control group [(0.53±0.04) cm vs. (3.65±0.46) cm, P<0.05]. Follow-up was conducted for 1 to 12 months in the two groups of patients, no tumor recurrence occurred, and scars of different lengths were noted in patients in control group, while the scars were very small or invisible in those in observational group. Conclusion: Resection of large benign breast tumor with ultrasound-guided Mammotome revolve device is safe and feasible, and offers favorable cosmetic results, so it has applicable value in clinical practice.
