超声引导穿刺活检对肺肿瘤的诊断价值

目的对其他检查方法不能做出定性诊断的肺肿瘤进行超声引导穿刺活检,探讨该方法对肺肿瘤的诊断价值.方法经胸超声检查确认肿瘤,并设定穿刺途径,采用日本八光21G PTC针,美国Bard自动活检枪和18G切割针.结果80例全部接受针吸细胞学检查,其中40例并接受组织学检查.细胞学检查诊断正确率为82.50%(66例),组织学检查诊断正确率为90%(36例).二种方法互补诊断正确率92.50%(74例).组织定性诊断正确率95%(76例).并发症4例(5%),其中气胸1例,咳血3例(3.75%),无严重并发症发生.结论超声引导穿刺活检对肺肿瘤的定性诊断为临床治疗提供了依据,有较高临床应用价值.

Diagnostic value of ultrasond - guided biopsy for pulmonary cancer

Objective To evaluate the value of ultrasound-guided biopsy in diagnosing of those pulmonary lesings that can' t be diagnosed by other examinations. Methods We indentified the tumors in the lung using ultrasound and determined the routine of guidance by perform fine-needle biopsy for the cytologic examination with 21 G PTC Nedle(Blakko, Japan) in 80 cases, and obtained adequate tissue for histologic examination with automatic biopsy gun and 18G tru-cut needle(Bard American) in 40 rase. Results The accuracy of cytologic examination was 82.5% (66 cases) , and the accuracy of histologic examination was 90% (36 cases) . When these two methods were combined, the accuracy was up to 92.5% (74 cases) , and 74 cases (95% ) got the right pathologic classification. Complications appeared in 4 cases(5%), including 1 case pneumothorax, and 3 cases hemoptysis. No serious complication occurred. Conclusions Differentiating diagnosis of the pulmonary tumors with ultrasound-guided biopsy can provide evidences for the clinic to make therapeutic plans, which has important clinical values.
