摘要

胰腺癌的预后较差,且发病率呈上升趋势。内镜超声成像(EUS)是一种高效可靠的胰腺病变诊断方法,具有很高的空间分辨率。然而,虽然 EUS 有助于检测胰腺轻微病变,但几乎所有胰腺实性病变都是低回声的,这给胰腺病变的鉴别诊断带来了困难。在诊断胰腺病变时,必须使用图像增强 EUS 技术,如 EUS 弹性成像或对比度增强谐波 EUS(CH-EUS)。CH-EUS诊断以评估病变的血管性为基础,而组织弹性则通过EUS弹性成像来测量。弹性成像是应变或剪切波,取决于所评估的不同机械特性。本综述展示了增强 EUS 技术在胰腺病变(包括实性和囊性病变)鉴别诊断和胰腺癌分期方面的实用性。

Role of contrast-enhanced harmonic endoscopic ultrasonography (EUS) and EUS elastography in pancreatic lesions.

Pancreatic cancers have a poor prognosis, and their incident rates have risen. Endoscopic ultrasonography (EUS) is an efficient and reliable diagnostic modality for pancreatic lesions, providing high spatial resolution. However, while EUS helps to detect minor pancreatic lesions, nearly all solid pancreatic lesions are hypoechoic, which creates difficulty in making differential diagnoses of pancreatic lesions. When diagnosing pancreatic lesions, the performance of image-enhanced EUS techniques is essential, such as EUS elastography or contrast-enhanced harmonic EUS (CH-EUS). CH-EUS diagnosis is based on assessing the vascularity of lesions, whereas tissue elasticity is measured via EUS elastography. Elastography is either strain or shear-wave, depending on the different mechanical properties being evaluated. The usefulness of enhanced EUS techniques is demonstrated in this review for the differential diagnosis of pancreatic lesions, including solid and cystic lesions, and pancreatic cancer staging.
