麦默通与Tru-cut活检针对乳腺肿块活检的对比分析

目的：比较超声引导下麦默通与Tru-cut活检针在乳腺肿块微创活检诊断中的价值。方法：将214例乳腺肿块患者分为麦默通与Tru-cut活检针2组，在超声引导下进行微创活检，比较其取材成功率及病检符合率。结果：麦默通组与活检针组取材成功率分别为100％和90％，病检符合率分别为98．7％和90％，两组比较差异有统计学意义（P〈0.05）。结论：超声引导麦默通微创穿刺乳腺肿块活检优于Tru-cut活检针，是目前病理活检诊断乳腺病变比较理想的取样方法。

Objective To compare the diagnostic value of ultrasound-guided mammotome and Tru-cut biopsy needle in diagnosing breast masses. Methods Retrospective analysis was performed in 214 patients with breast masses obtained separately by mammotome or Tru-cut biopsy needle guided by ultrasound, and analyzed by pathological examination. The success ratios of sample choosing and the coincident ratios of pathological diagnosis were compared. Results The success ratios of sample choosing for mammotome and Tru-cut biopsy needle were 100% and 90%, respectively. The coincident ratios of pathological diagnosis of mammotome and Tru-cut were 98.7% and 90%, respectively. There was significant difference in the 2 groups (P<0.05). Conclusion Mammotome is a useful method and superior to Tru-cut biopsy needle in the diagnosis of breast masses.
