目的：比较市售 14 号核心活检枪以及 11 号和 14 号定向真空辅助活检探头的组织产量和碎片情况。 材料和方法：使用 11 个 14 号自动活检枪针组合以及配备 11 号定位器的定向、立体定向、真空辅助活检系统，对新鲜火鸡乳房进行 100 次穿刺。或 14 号探头。测量样本的总重量、个体长度、直径和碎片数量。 结果：在手持设备中，Pro-Mag 2.2 枪（Manan Medical Products，诺斯布鲁克，伊利诺伊州）和 14 号 Biopty-Cut 针（Bard，科文顿，佐治亚州）产量最高（每个核心样本 17.7 毫克）；这种组合还产生了最大比例的未碎片核心（83%）。定向真空辅助活检样本明显更大 (P < .001)：14 号探针的每个核心样本为 36.8 mg，11 号探针的每个核心样本为 94.4 mg。通过定向真空辅助活检获得的样本比通过弹簧驱动、两级、长行程、自动活检系统获得的样本更破碎。结论：各种活检装置在乳腺组织产量和碎片方面存在统计学上的显着差异。
PURPOSE: To compare commercially available 14-gauge core biopsy guns and 11- and 14-gauge, directional, vacuum-assisted biopsy probes for tissue yield and fragmentation.MATERIALS AND METHODS: One hundred passes were made through fresh turkey breasts by using each of 11 14-gauge, automated biopsy gun-needle combinations and a directional, stereotactic, vacuum-assisted biopsy system equipped with 11- or 14-gauge probes. Specimens were measured for total weight, individual length, diameter, and number of fragments.RESULTS: Among the handheld devices, the Pro-Mag 2.2 gun (Manan Medical Products, Northbrook, Ill) and 14-gauge Biopty-Cut needle (Bard, Covington, Ga) had the greatest yield (17.7 mg per core specimen); this combination also produced the greatest percentage of nonfragmented cores (83%). Directional, vacuum-assisted biopsy specimens were significantly larger (P < .001): 36.8 mg per core specimen for the 14-gauge probe and 94.4 mg per core specimen for the 11-gauge probe. Specimens obtained with directional, vacuum-assisted biopsy were more fragmented than those obtained with spring-actuated,two-stage,long-throw, automated biopsy systems.CONCLUSION: Statistically significant differences with various biopsy devices are seen in the breast tissue yield and in fragmentation.
