摘要
超声内镜结合了内镜技术与超声技术,在其基础上衍生出超声内镜对比增强和弹性成像等新技术。目前,大量研究显示,相比于传统影像学技术,超声内镜对比增强在发现胰腺癌原发灶、判断是否合并局部血管侵犯、淋巴结转移及肝脏转移等方面具有传统影像学不可替代的优势,可为胰腺癌,特别是小胰腺癌的诊断、TNM分期以及明确根治性手术适应证等方面提供重要依据。超声内镜弹性成像亦可做为胰腺癌诊断的重要辅助手段。此外,在超声内镜引导下可以行细针穿刺活检,获取病理学标本。
Based on ultrasound endoscopy which combines endoscopic technology and ultrasound technology,contrastenhanced endoscopic ultrasonography and endoscopic ultrasound elastography are derived. Recently,a large amount of literature have demonstrated that compared with traditional imaging techniques, contrast-enhanced endoscopic ultrasonography has irreplaceahle advantages in discovering pancreatic cancer and evaluating local vascular invasion,lymph node metastasis and liver metastasis. This novel technique can provide crucial evidence for diagnosis of pancreatic cancer,(especially small pancreatic cancer),TNM staging,and clarifying indications for radical surgery. Endoscopic ultrasound elastography can also be regarded as an important assistant method in the diagnosis of pancreatic cancer. In addition,fine needle aspiration can be performed under the guidance of endoscopic ultrasonography to obtain pathology specimens.
