内镜超声在诊断和治疗肝脏疾病中的价值

肝脏疾病的传统影像学诊断方法主要包括B超、CT、MRI等,内镜超声(EUS)以往较少用于肝脏疾病的诊断。近年,EUS和EUS-细针穿刺活检(FNA)在肝脏疾病的诊断中取得了较大进展,对B超、CT、MRI难以发现的微小病变有一定诊断价值,且EUS-FNA可获得较好的组织学和细胞学标本,有助于明确微小病变的性质。本文就EUS和EUS-FNA在肝脏疾病,尤其是肝癌诊断中的价值作一综述,旨在提高医师对两者临床应用的认识。

Value of Endoscopic Ultrasonography in the Diagnosis and Treatment of Liver Diseases

The diagnosis of liver diseases was traditionally performed by ultrasound, CT or MRI, while endoscopic uhrasonography （EUS） was used unusually. However, in recent years EUS and EUS-fine needle aspiration （EUS-FNA） developed rapidly, and were used for the diagnosis of various liver diseases that could not be detected by ultrasound, CT or MRI. Through EUS-FNA, satisfactory liver specimens could be obtained and the nature of some minute liver diseases could be defined clearly. This article reviewed the clinical significance of EUS and EUS-FNA in the diagnosis of liver diseases, especially liver cancer, for promoting their clinical application.
