目的:评价B型超声引导下胸膜活检在老年胸腔积液病因诊断中的价值。方法:选择年龄≥60岁,胸腔积液病人50例,随机分成2组,每组25人,分别为B超组即B超引导下胸膜活检组;CT组即CT引导下胸膜活检组。观察检出率、确诊率、并发症等。结果:B超组恶性肿瘤确诊率为76.00%(19/25),结核性胸膜炎确诊率为8.00%(2/25),阴性为16%(4/25),总检出率为84.00%;CT组恶性肿瘤确诊率为60.00%(15/25),结核性胸膜炎确诊率为4.00%(1/25),阴性为36.00%(9/25),总检出率为64.00%。结论:B超引导下经皮胸膜穿刺活检确诊率及总检出率明显优于CT引导下经皮胸膜穿刺活检,同时B超较CT无辐射、操作上更方便、费用更低,所以可成为老年胸腔积液患者确诊常规应用手段。
Objective: To evaluate the value of pleural biopsy guided by B-mode ultrasonography in the etiological diagnosis of senile pleural effusion. Methods: A total of 50 patients with pleural effusion were selected and randomly divided into 2 groups (25 in each group). They were B-ultrasonography-guided pleural biopsy and CT-guided pleural biopsy. Observe the detection rate, the diagnosis rate, complications and so on. Results: The diagnosis rate of malignant tumor in group B was 76.00% (19/25), the diagnosis rate of tuberculous pleurisy was 8.00% (2/25), the negative rate was 16% (4/25), the total detection rate was 84.00%. The diagnosis rate of malignant tumor in CT group was 60.00% (15/25), the diagnosis rate of tuberculous pleurisy was 4.00% (1/25), the negative rate was 36.00% (9/25), the total detection rate was 64.00%. Conclusion: The diagnostic rate and the total detection rate of percutaneous pleural puncture biopsy under B-ultrasound are significantly better than CT-guided percutaneous pleural biopsy. At the same time, B ultrasound has no radiation compared with CT, which is more convenient and less expensive to operate, so it can become Elderly patients with pleural effusion confirmed the use of conventional means.
