超声引导下穿刺活检乳腺肿物的临床研究

目的探讨超声引导下粗针穿刺活检在乳腺肿物诊断中的价值，比较14G及16G活检针的优缺点。方法高频超声引导下14G或16G活检针经皮穿刺活检150例乳腺肿物，以术后病理诊断为标准，分析经皮粗针活检对乳腺肿物的诊断准确性。结果150例乳腺病灶穿刺活检准确率约87．3％。68例用14G针活检，取材成功率91．3％，并发症7．3％；72例用16G针活检，取材成功率91．7％，并发症8．3％。结论超声引导14G及16G针穿刺活检同样具有成功率高、安全、病理组织学诊断准确率高等优点，可为临床诊断和治疗提供重要依据。

Clinical research on sonography-guided core needle biopsy in breast masses

Objective To investigate the value of sonography-guided core needle biopsy in breast masses and to compare the accuracy and safety with 14G and 16G needle in biopsy. Methods 150 breast masses received sonography-guided needle （14G/16G） biopsy, and comparing with the results of operative pathology, the accuracy of diagnoses by biopsy was analyzed. Results The diagnosis accuracy of sonography-guided ueedle（14G/16G） biopsy was 92.7%. 14G was applied in 68 cases and 16G in 72 cases, with the accuracy of successfully puncturing and complication at 91.3%, 7.3% and 9L7%, 8.3% respectively. Conclusion No significant difference was found between the two types of needles. Sonography-guided needle biopsy provides a safe, accurate and less traumatic procedure for diagnosis in breast masses.
