目的:探讨超声引导下切割式胸膜活检的临床应用价值。方法:对原因不明的渗出性胸腔积液308例行超声引导下切割式胸膜活检,以术后病理诊断或随访至少12个月以上结果为最终诊断,分析取材成功率和穿刺活检准确度、灵敏度及特异性。结果:本组单次穿刺取材成功率98.1%。结核性胸膜炎超声引导下切割式胸膜活检准确度为83.0%、灵敏度为76.6%、特异性为100.0%,胸膜恶性肿瘤准确度为95.8%、灵敏度为75.0%、特异性为100.0%,胸膜非特异性炎症准确度为80.8%、灵敏度为90.6%、特异性为78.8%。结论:超声引导下切割式胸膜活检具有简单快速、微创安全、易于推广等特点,是不明原因胸腔积液的理想确诊方法。
Objective: To investigate the clinical value of ultrasound-guided cut pleural biopsy. Methods: Thirty-eight patients with unexplained exudative pleural effusion underwent ultrasound-guided cutting pleural biopsy. The postoperative pathological diagnosis or follow-up of at least 12 months was the final diagnosis. The success rate of sampling and biopsy accuracy were analyzed. Sensitivity and specificity. Results: The success rate of single puncture in this group was 98.1%. The diagnostic accuracy of the pleural pleural biopsy was 83.0%, the sensitivity was 76.6%, the specificity was 100.0%, the accuracy of pleural malignancy was 95.8%, the sensitivity was 75.0% and the specificity was 100.0%. The pleural nonspecificity The accuracy of inflammation was 80.8%, the sensitivity was 90.6% and the specificity was 78.8%. Conclusion: Ultrasound-guided cut pleural biopsy has the characteristics of simple, quick, minimally invasive and easy to popularize. It is an ideal method for diagnosing unexplained pleural effusion.
