目的：探讨超声引导下8-gauge 麦默通真空辅助活检系统（UVMS）在乳腺肿物诊断和治疗中的应用价值。方法：回顾性分析2012 年1 月—2013 年12 月1 157 例行UVMS 处理乳腺肿物患者（共3 702 个肿物）的临床资料。结果：全部肿物均采用UVMS 切除。1 157 例患者中，888 例（76.75%）无可触及肿物，831 例（71.82%）为多发肿物，245 例（21.18%） 双侧乳腺病变。病灶长径平均11.2（3~35）mm， 平均切除时间15（3~90）min，平均出血量8（1~40）mL，皮肤伤口长度3~5 mm。标本病理诊断大多数为良性病变（99.57%），其中以纤维腺瘤为主（64.61%）。术后出现血肿53 例，皮下瘀斑26 例，乳头溢血2 例，无其他严重并发症。结论：UVMS 切除乳腺肿物具有简单安全、微创等特点，尤其适用于乳房多发隐匿性肿物的诊治，但需要严格控制手术适应证。
Application of ultrasound-guided vacuum-assisted Mammotome system in diagnosis and treatment of breast masses: a report of 1 157 cases
Objective: To investigate the application value of ultrasound-guided vacuum-assisted 8-gauge Mammotome biopsy system (UVMS) in diagnosis and treatment of breast masses. Methods: The clinical data of 1 157 patients with breast masses (a total of 3 702 lesions) undergoing UVMS treatment from January 2012 to December 2013 were retrospectively analyzed. Results: All lesions were removed by UVMS. Among the 1 157 patients, 888 cases (76.75%) had no palpable mass, 831 cases (71.82%) had multiple lesions, and 245 cases (21.18%) had bilateral lesions. The average longitudinal diameter of the lesions was 11.2 (3–35) mm, the average operative time was 15 (3–90) min, the average blood loss was 8 (1–40) mL, and the length of incision ranged from 3 to 5 mm. The majority of the specimens (99.57%) were pathologically diagnosed to be benign lesions, in which fibroadenoma was the dominant one (64.61%). After operation, hematoma occurred in 53 cases, subcutaneous ecchymosis occurred in 26 cases, bloody nipple discharge in 2 cases, and no other severe complications were observed. Conclusion: The application of UVMS for removal of breast masses is simple, safe and minimally invasive, and is especially suitable for multiple and impalpable masses, but the indications should be strictly controlled.
