目的探讨超声引导下细针吸取细胞学检查在肝脏实质性病变诊断中的价值。方法对１６０４例肝脏实质性病变施行超声引导下肝穿刺的结果进行分析。结果肝穿刺诊断恶性肿瘤的敏感性为９２１０％，诊断正确率为９２８３％，假阴性率为６５９％。结论超声引导下细针吸取细胞学检查是对肝脏实质性病变诊断和鉴别诊断的一种简便、迅速、安全、有效的方法。对肝穿刺阴性的病例应密切追踪随访，必要时再作穿刺以明确诊断。
Objective To investigate the value of ultrasound-guided fine needle aspiration cytology in the diagnosis of hepatic parenchymal lesions. Methods The results of ultrasound-guided hepatic puncture in 1604 cases of hepatic parenchymal lesions were analyzed. Results The sensitivity of liver biopsy for diagnosis of malignant tumors was 9210%, the diagnostic accuracy rate was 9283%, and the false negative rate was 659%. Conclusion Ultrasound-guided fine needle aspiration cytology is a simple, rapid, safe and effective method for the diagnosis and differential diagnosis of hepatic parenchymal lesions. Cases with negative liver puncture should be closely followed up, and puncture should be performed if necessary to confirm the diagnosis.
