目的:应用超声导向肝穿活检,明确肝内占位病变性质,选择最佳治疗手段。材料和方法:使用Aloka-SSD-250及AL-310B超仪,35MHz线阵穿刺探头及18或22号带针芯长针,对284例性质不明的肝内占位病变进行实时超声引导下肝穿针吸细胞学检查,并与手术病理结果对照,回顾性验证肝穿细胞学诊断准确性,分析了小肝癌与炎性假瘤声像图特征。结果:本组284例,肝穿细胞学诊断恶性肿瘤符合率906%,良性肿瘤诊断符合率947%,小肝癌诊断符合率918%。结论:本法安全简便,快速准确,为肝内良恶性占位诊断及鉴别诊断的首选方法。
Objective: To apply ultrasound-guided liver biopsy to identify the characteristics of intrahepatic space-occupying lesions and to choose the best treatment. MATERIALS AND METHODS: A total of 284 patients with unidentified intrahepatic space-occupying lesions underwent real-time ultrasound guidance using Aloka-SSD-250 and AL-310B supervisors, 3.5MHz line array probes and 18- or 22-gauge needles Under the needle aspiration cytology, and compared with the surgical pathology results, retrospective verification of the diagnostic accuracy of the liver through cytology, analysis of small hepatocellular carcinoma and inflammatory pseudotumor sonographic features. Results: 284 cases of this group had a coincidence rate of 90.6% for diagnosis of hepatocellular carcinoma, 94.7% for benign tumor and 91.8% for small hepatocellular carcinoma. Conclusion: This method is safe, simple, rapid and accurate, and is the preferred method for the diagnosis and differential diagnosis of benign and malignant liver lesions.
