Mammotome® biopsy system for the resection of breast lesions: Clinical experience in two high-volume teaching hospitals

Abstract

Ultrasound-guided vacuum-assisted breast biopsy (VABB) is regarded as a feasible, effective, minimally invasive and safe method for the removal of benign breast lesions, without the occurrence of serious complications. The aim of this study was to evaluate the feasibility, efficacy and safety of ultrasound-guided VABB using the Mammotome® biopsy system in the treatment of breast lesions. The clinical outcomes of 3,681 patients with breast lesions were evaluated following excisions by ultrasound-guided VABB in two high-volume teaching hospitals. From January 2008 to December 2012, a total of 4,867 ultrasound-guided VABB procedures were performed in the 3,681 patients, who had a mean age of 37.8 years (range, 16–73 years). The parameters examined in this analysis included lesion size, lesion location in the inner breast, Breast Imaging Reporting and Data System (BI-RADS) ultrasound category and histopathological diagnosis. Ultrasonography follow-up was performed at 3–6 month intervals in order to assess recurrence. The size of the investigated lesions ranged between 6 and 62 mm and a histopathological diagnosis was made in 100% of cases. The results indicated that the majority of specimens (98.89%) were benign. On average, the ultrasound-guided VABB was performed in 10.3 min (range, 7.5–43 min) and the mean number of cores removed in the procedure was 8.1 (range, 3–32). A complete excision was achieved in the majority of cases (99.7%). The presence of a hematoma was the most common complication following the biopsy, and was observed in 27.5% of patients. The mean follow-up period was 25.5 months (range, 1–60 months), during which the rate of recurrence was 4.4%. The results indicated that ultrasound-guided VABB using the Mammotome biopsy system is an effective and safe procedure that is able to rapidly remove the majority of benign breast lesions using a small incision and without the occurrence of scarring or complications.

Minimally Invasive Breast Fibroadenoma Excision Using an Ultrasound-Guided Vacuum-Assisted Biopsy Device

“…Haematoma formation is the most common complication. 27 out of 30 patients reported haematoma development though the majority were not of therapeutic consequence [7,10,13,14]. In our survey all patients stated they would undergo the biopsy again if necessary.…”

Vacuum-Assisted Aspiration Biopsy: Minimally Invasive Treatment for Benign Breast Tumors (A Literature Review)

“…Время, затрачиваемое на ВАБ с тотальным удалением образования в молочной железе, варьирует от 10 до 60 мин [16,28,31,33,38,39,43] и зависит от размера опухоли, ее местоположения и характера окружающих тканей [28]. Время давления после ВАБ на область вмешательства (с целью гемостаза) варьирует от 5 до 20 мин [12,13,22,29,43].…”

“…Время давления после ВАБ на область вмешательства (с целью гемостаза) варьирует от 5 до 20 мин [12,13,22,29,43]. Эластический бинт после процедуры, по различным данным, накладывают на 18-72 ч [12,17,27,38].…”

“…В качестве обезболивания при выполнении ВАБ применяют местную анестезию и чаще используют 2 % раствор лидокаина с адреналином [35], 1 % рас-твор лидокаина или 1 % раствор лидокаина с адрена-лином [13,16,27,28,38,43,51], 2 % раствор лидокаи-на или 0,5 % раствор маркаина [52,53]. В России вакуумную резекцию доброкачественных образований также выполняют и под местной анестезией с приме-нением раствора норапина с адреналином.…”

“…Частота осложнений тотальной ВАБ (вакуумной резекции) варьирует от 0 до 9 % [11,26,27,29], ча-стота образования гематом после ВАБ составляет 4,5-27,5 % [16,27,33,38]. По наблюдениям E. S. Ko и соавт.…”
