Endoscopic ultrasound (EUS) has evolved to become a crucial tool for the evaluation of pancreatic diseases, among them solid pancreatic lesions. However, its ability to determine whether a lesion is malignant or not is difficult to establish based only in the endosonographic image. EUS-guided fine needle aspiration (EUS-FNA) allows obtaining a cytological and/or histological sample from pancreatic lesions, with a high overall accuracy and low complication rates. Although the clinical usefulness of EUS-FNA for pancreatic diseases is widely accepted, the indications for tissue diagnosis of pancreatic lesions suspected to be malignant is still controversial. This review highlights the diagnostic accuracy and complications of EUS-FNA, focusing on its current indications.
内镜超声（EUS）已经发展成为评估胰腺疾病（包括实性胰腺病变）的重要工具。然而，仅根据内镜超声图像很难确定病变是否为恶性。EUS 引导下细针抽吸（EUS-FNA）可从胰腺病变中获得细胞学和/或组织学样本，具有较高的总体准确性和较低的并发症发生率。尽管 EUS-FNA 对胰腺疾病的临床应用已被广泛接受，但对于疑似恶性的胰腺病变进行组织诊断的适应证仍存在争议。本文重点介绍 EUS-FNA 的诊断准确性和并发症，并探讨其当前的适应证。
