Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is widely used to obtain a definitive diagnosis of pancreatic tumors. Good results have been reported for its diagnostic accuracy, with high sensitivity and specificity of around 90%; however, technological developments and adaptations to improve it still further are currently underway. The endosonographic technique can be improved when several tips and tricks useful to overcome challenges of EUS-FNA are known. This review provides various techniques and equipment for improvement in the diagnostic accuracy in EUS-FNA.
内镜超声引导下细针抽吸术（EUS-FNA）广泛用于获得胰腺肿瘤的明确诊断。其诊断准确性的结果良好，灵敏度和特异性均在 90%左右；然而，目前仍在进行技术开发和适应以进一步提高其性能。当了解到有助于克服 EUS-FNA 挑战的各种技巧和窍门时，超声内镜技术可以得到改善。本文综述了各种提高 EUS-FNA 诊断准确性的技术和设备。
