To evaluate the feasibility and safety of vacuum-assisted resection of benign breast tumours using an 8 G handheld device.
Over a 2-year period, 22 patients with 26 breast tumours diagnosed as benign using aspiration biopsy cytology were enrolled. The mean patient age was 38 years, and the mean maximal diameter of the tumour was 13 mm. A handheld Aloka SSD 6500 ultrasonography device with a linear-type 7.5 MHz transducer was inserted into the posterior aspect of the tumour with the patient under local anaesthesia, and the tumour was resected under ultrasonographic guidance.
This method was employed successfully in all patients, and the mean operation time was 33 min. Post-procedure complications included subcutaneous bleeding in 12 cases and haematoma in one. The pathological diagnoses were fibroadenoma in 16 cases, mastopathy in six, and tubular adenoma and pseudoangiomatous stromal hyperplasia in two cases each, respectively. Follow-up ultrasonography revealed residual tumours in four cases (15.4%).
Although this method is feasible and safe without severe complications, it is necessary to select appropriate patients, and to obtain informed consent regarding the possibility of recurrence or residual tumour.
评估使用8G手持设备真空辅助切除乳腺良性肿瘤的可行性和安全性。
在2年的时间里，纳入了22例经细针穿刺活检细胞学诊断为良性的26个乳腺肿瘤患者。患者平均年龄为38岁，肿瘤平均最大直径为13mm。在局部麻醉下，将带有线性7.5MHz换能器的手持阿洛卡SSD 6500超声设备插入肿瘤后方，在超声引导下切除肿瘤。
该方法在所有患者中均成功应用，平均手术时间为33分钟。术后并发症包括12例皮下出血和1例血肿。病理诊断为纤维腺瘤16例，乳腺病6例，管状腺瘤和假血管瘤性间质增生各2例。随访超声检查发现4例（15.4%）有残留肿瘤。
尽管该方法可行且安全，无严重并发症，但有必要选择合适的患者，并就复发或残留肿瘤的可能性获得知情同意。
