目的 评估超声引导下真空辅助旋切对乳腺良性疾病手术切除的临床应用价值.方法 回顾性研究2009年1月~2014年1月在贵阳市妇幼保健院乳腺科进行乳腺微创旋切手术的1267名乳腺良性疾病患者在切除率、并发症发生率、复发率及满意度方面临床随访结果及对相关危险因素分析.术后于1月、6月及其后每6月进行随访至2年(中位随访22个月).结果(1)1267例中1259例完全切除,8例术后1月发现残留,手术切除率99.36%.手术切除率与病灶大小相关(P=0.003),而与年龄、BI-RADS分级、病灶数目及位置无明显相关(P值均>0.05).(2)1267例中89例出现并发症(7.02%),其中血肿70例(5.52%),发生率与病灶数目及位置相关(P=0.000),而与年龄、BI-RADS分级、病灶大小无明显相关(P值均>0.05).(3)1267例中193例患者被确诊有复发,复发率15.23%,其中原位复发65例(5.13%),新发病变128例(10.1%).复发率与病灶数目及大小相关(P=0.000),而与年龄、BI-RADS分级、病灶位置无明显相关(P值均>0.05).(4)1267例患者有6例对手术外观不满意,患者满意度达99.52%.结论 超声引导下MMT真空辅助旋切对乳腺良性疾病是一种安全有效的手术,手术并发症少,切除率高,复发率低,对良性和高风险乳腺病变,特别是多发性乳房良性病变具有满意的外观效果.%Objective To assess the clinical value of ultrasound-guided vacuum-assisted Mammotome (MMT) system for surgical resection of benign breast disease. Methods This retrospective study was conducted among 1267 patients who underwent minimally invasive surgery with ultrasound-guided MMT system for benign breast disease at our center between January, 2009 and January, 2014. The resection rate, incidence of complication, recurrence rate, patients' satisfaction, clinical follow-up results and risk factors were analyzed. The patients were followed up at 1 month, 6 months and every 6 months thereafter for up to 2 years with a median follow-up of 22 months. Results Of the total of 1267 patients, 1259 (99.36%) had complete resection of the breast lesions, and residual lesions were found in 8 cases 1 month after the operation. The resection rate was significantly associated with lesion size (P=0.003) but not with the patients'age, pathology, BI-RADS classification, or the number or location of the lesions (P>0.05). Eighty-nine (7.02%) patients showed postoperative complications, and hematoma occurred in 70 (5.52%) patients after the operation. The complication rate was significantly associated with the number and location of lesions (P=0.000) but not with age, pathology, BI-RADS classification or the lesion size (P>0.05). A total of 193 (15.23%) patients had recurrence after the operation, including 65 (5.13%) with in situ recurrence and 128 (10.1%) with new lesions. The recurrence rate was significantly associated with the number and size of lesions (P=0.000) but not with age, pathology, BI-RADS classification or location of lesions(P>0.05). Six patients were not satisfied with the appearance of the incision, and the overall satisfaction rate of the patients was 99.52%. Conclusions Ultrasound-guided vacuum-assisted MMT excision is a safe and effective procedure for benign breast disease with a low surgical complication rate, a high resection rate and a low recurrence rate. This technique results in good postoperative appearance for treatment of benign and high-risk breast lesions, especially multiple benign breast lesions.
