Abstract

Endoscopic ultrasonography (EUS) provides high spatial and contrast resolution and is a useful tool for evaluating the pancreato-biliary regions. Recently, contrast-enhanced harmonic EUS (CH-EUS) has been used to evaluate lesion vascularity, especially for the diagnosis of pancreatic tumors. CH-EUS adds two major advantages when diagnosing pancreatic cystic lesions (PCL). First, it can differentiate between mural nodules and mucous clots, thereby improving the accurate classification of PCL. Second, it helps with evaluation of the malignant potential of PCL, especially of intraductal papillary mucinous neoplasms by revealing the vascularity in the mural nodules and solid components. This review discusses the use and limitations of CH-EUS for the diagnosis of PCL.

摘要

内镜超声检查（EUS）具有高空间分辨率和对比分辨率，是评估胰胆区域的有用工具。近年来，对比增强谐波内镜超声检查（CH-EUS）已用于评估病变血管情况，尤其用于胰腺肿瘤的诊断。CH-EUS在诊断胰腺囊性病变（PCL）时具有两个主要优势。其一，它可以区分壁结节和黏液凝块，从而提高PCL的准确分类。其二，它有助于评估PCL的恶性潜能，特别是通过显示壁结节和实性成分中的血管情况来评估导管内乳头状黏液性肿瘤的恶性潜能。本文综述了CH-EUS在PCL诊断中的应用及局限性。
