BACKGROUND/AIM: Endoscopic ultrasound (EUS)-guided liver tumor biopsy has some advantages over the percutaneous and surgical route and, in many cases, should be preferred. The aim of this study was to evaluate the role of EUS-fine needle aspiration (FNA) in the diagnosis of liver tumors with an emphasis on its diagnostic accuracy and histological quality of the acquired specimen.
PATIENTS AND METHODS
We followed 30 consecutive patients who underwent liver tumor biopsy using EUS guidance. Tissue was acquired using a 22-gauge FNA needle.
RESULTS
In 97% of patients, the results of EUS-FNA were adequate for diagnosis. In one case, the pathologist recommended a repeat biopsy. The acquired specimen was a core fragment in 81% of cases while in 19% of cases the specimen was fragmented and subsequently used as a cell block. No complications were reported.
CONCLUSION
EUS-FNA is characterized by a high success rate on the acquisition of good-quality tissue specimens, a low rate of complications, and decreased patient discomfort. This procedure should be especially considered in the case of liver lesions that are inaccessible via the percutaneous route or when concurrent biopsies are required for accurate diagnosis.
背景/目的：与经皮和手术途径相比，内镜超声（EUS）引导下的肝肿瘤活检具有一些优势，在许多情况下应优先选择。本研究的目的是评估 EUS-细针抽吸（FNA）在肝肿瘤诊断中的作用，重点是其诊断准确性和获得标本的组织学质量。
患者和方法
我们随访了 30 例连续接受 EUS 引导下肝肿瘤活检的患者。使用 22 号 FNA 针采集组织。
结果
在 97%的患者中，EUS-FNA 的结果足以进行诊断。在 1 例中，病理学家建议重复活检。采集的标本 81%为核心组织碎片，19%为碎片，随后用作细胞块。未报告任何并发症。
结论
EUS-FNA 的特点是采集高质量组织标本的成功率高、并发症发生率低且患者不适感降低。对于经皮途径无法触及的肝病变或需要进行准确诊断的同时进行的活检，应特别考虑此操作。
