Abstract：
The caudate lobe of the liver is located deep within the body and surrounded by major blood vessels, such as inferior vena cava, portal vein, and hepatic veins. Thus, percutaneous biopsy is technically challenging. Herein, we report seven patients with focal liver lesions in the caudate lobe who underwent endoscopic ultrasound-guided tissue acquisition (EUS-TA). Their median age was 56 (25-79) years, consisting five males and two females, and the median lesion size was 44 (19-77) mm. Transgastric EUS-TA was performed in all patients. The needles used were 22G and 25G in six patients and one patient, and the median procedure time was 18 (13-30) min. In all patients, adequate specimens were collected, and pathological diagnosis was possible (three intrahepatic cholangiocarcinoma, two metastatic tumors from pancreatic cancer, one hepatocellular carcinoma, and one focal nodular hyperplasia). No adverse events associated with the procedure were observed. EUS-TA can be the first choice for tissue acquisition of the caudate lobe lesions.
摘要：
肝脏的尾状叶位于身体深处，被主要血管包围，比如下腔静脉,门静脉,和肝静脉.因此，经皮活检在技术上具有挑战性。在这里，我们报告了7例接受内镜超声引导组织采集(EUS-TA)的尾状叶局灶性肝脏病变患者.他们的平均年龄为56（25-79）岁，由五名男性和两名女性组成，中位病变大小为44（19-77）mm。所有患者均进行经胃EUS-TA。6名患者和1名患者使用的针头分别为22G和25G，中位手术时间为18(13-30)min。在所有患者中，收集了足够的标本，和病理诊断是可能的（三个肝内胆管癌，两个来自胰腺癌的转移性肿瘤，一个肝细胞癌，和一个局灶性结节增生）。没有观察到与该程序相关的不良事件。EUS-TA可以是组织获取尾状叶病变的首选。
