摘要
目的：探讨超声引导下经皮穿刺活检对AFP阴性肝脏占位性病变的诊断价值。方法：采用18G枪式自动活检针在超声引导下对50例AFP阴性的肝脏占位性病变进行穿刺活检,所取组织进行组织病理学检查。结果：所有患者均成功施行超声引导下经皮肝穿刺活检术,每例取材1～3次,所有组织均符合病理诊断要求且均得到组织病理学诊断,其中原发性肝癌占32%（16/50）,转移性肝癌占44%（22/50）,良性病变占24%（12/50）。除1例患者出现肝脏包膜下少量出血外,其余患者均未出现并发症。结论：超声引导下经皮穿刺活检操作安全、简便、快速,成功率高,并发症少、结果可靠,是AFP阴性肝脏占位性病变定性诊断的首选方法。
Objective.. To investigate the value of ultrasound-guided core-needle biopsy （US-CNB） in diagnosis of AFP negative space-occupying liver lesions. Methods： 50 patients with AFP negative space-occupying liver lesions were received automatic gun biopsy using coarse needle （18G）. The obtained samples were sent for histopathological diagnosis. Results： US-CNB was performed successfully in all patients. The mean puncture times were 1～ 3. All specimens were satisfactory for the histopathological evaluation and got the diagnosis respectively. Among the 50 cases, there are 16 （32 %） primary liver cancer,22 （44 %） metastatic liver cancer and 12 （24%） benign liver lesions. Only one case was found slight hemorrhage below the liver capsule,there are no complications in other cases. Conclusion： US-CNB is safe, easy, rapid and having high success rate and low complications and trustable results. It is the preferred technique to confirm the quality of the AFP negative space-occupying liver lesions.
