Endoscopic ultrasound (EUS) provides detailed, high-resolution images of the pancreas. However, whether a lesion is malignant or benign cannot be diagnosed solely from its imaging features on EUS. The introduction of EUS-guided fine needle aspiration (EUS-FNA) offers the possibility to obtain a cytological or histological diagnosis of pancreatic lesions with a high sensitivity and specificity. Although the clinical utility of EUS-FNA for pancreatic diseases is widely accepted, the indication for preoperative tissue diagnosis of pancreatic lesions suspected to be malignant is still controversial. This review highlights the diagnostic potential of EUS-FNA, as well as its current indications and contraindications, complications, and techniques.
内镜超声（EUS）提供了胰腺的详细、高分辨率图像。然而，仅凭 EUS 上的病变影像学特征，无法诊断其是恶性还是良性。EUS 引导下细针抽吸（EUS-FNA）的引入提供了获得胰腺病变细胞学或组织学诊断的可能性，具有较高的灵敏度和特异性。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术前组织诊断的适应证仍存在争议。本文重点介绍了 EUS-FNA 的诊断潜力，以及其目前的适应证和禁忌证、并发症和技术。
