目的对比研究细针不抽吸法与抽吸法活检术对胸部恶性病变的诊断价值。方法在超声导向下对胸部X线片和（或）CT疑诊为恶性病变的50例患者同一病变上作了细针不抽吸法与抽吸法活俭术。结果不抽吸法与抽吸法细胞学检查对胸部恶性病变诊断的敏感性均为90％（38／42），抽吸法细胞学加组织学检查敏感性为92．8％（39／42），2者经统计学处理无显著性差异（P＞0，05），两种方法对胸部恶性病变诊断的特异性均为100％。结论细打不抽吸法活俭术与抽吸法活检术同样为诊断胸部恶性病变的可靠方法。不抽吸法操作简单，但取得组织学检查材料成功率很低是其不足。
Objective To compare the diagnostic value of fine needle aspiration and aspiration biopsy for thoracic malignant lesions. Methods Fine needle aspiration and aspiration were performed on the same lesion in 50 patients who underwent ultrasound-guided chest X-ray and/or CT malignancy. Results The sensitivity of aspiration and aspiration cytology for the diagnosis of thoracic malignant lesions was 90% (38/42). The sensitivity of aspiration cytology plus histological examination was 92.8% (39/42). ), 2 statistically no significant difference (P> 0,05), the two methods for the diagnosis of thoracic malignant lesions were 100% specificity. Conclusions Puncturing without aspiration and aspiration biopsy are also reliable methods for diagnosing malignant lesions of the chest. The non-suction method is simple, but the low success rate of obtaining histological examination materials is insufficient.
