摘要
目的评价超声引导经皮活检诊断肝内小的（≤3cm）局灶性病变的准确性。方法从2000-2006年共190例病人193个肝内小病灶通过肝活检来明确病变的性质，病灶平均大小为（2．3±0．7）cm（0．6～3cm），肝内病灶直径≤1cm22个，1．1～2cm74个，2．1～3cm97个，活检全部采用自动活检枪，配18G活检针，采用超声引导下徒手穿刺技术。结果没有并发症发生，有187例（98．4％）取样足够用于诊断，组织病理学诊断结果包括恶性肿瘤149例，良性肿瘤19例，非肿瘤性病变22例。诊断敏感性为98．0％，特异性为100％，阳性预测值为100％，阴性预测值为92．7％，准确性为98．4％。结论超声引导经皮活检对于诊断肝内小的病变具有相当高的准确性和安全性。
Objective To evaluate the efficacy of US-guided percutaneous biopsy in the diagnosis of small（≤3 cm） focal hepatic lesions. Methods From January 2000 to December 2006, 190 consecutive patients with 193 discrete focal hepatic lesions received liver biopsy in our hospital to confirm the exact nature of the lesions. Mean lesion size was（2.3±0.7） cm（0. 6-3 cm）. Twenty-two biop- sies were performed on lesions ≤1 cm, 74 on lesions 1.1-2 cm and 97 on those 2.1-3 cm in diameter. Biopsy was performed using an 18-gauge automated needle under the guidance of US. Results No significant post-blopsy complication occurred. The biopsy specimen was sufficient for diagnosis in 187 cases（98.4%）. Histological examination revealed various types of primary and secondary malignant tumors（n= 149）, benign tumors（n= 19） and benign non-neoplastic conditions（n= 22）. The sensitivity and specificity for diagnosis were 98.0% and 100%, respectively. The positive and negative values were 100% and 92.7%. The accuracy was 98.4%. Conclusion US-guided percutaneous biopsy is highly accurate and safe in providing a definitive histological diagnosis for small hepatic lesions.
