超声内镜检查与胰腺疾病内镜治疗

超声内镜检查原理与腹部超声相似,其区别只是将微型高频超声探头安装在内镜顶端,进行实时超声扫描.胰腺是腹膜后器官,由于EUS插入胃和十二指肠肠腔内扫查,可清晰显示胰腺结构.随着EUS的广泛应用和内镜附件发展,EUS在胰腺疾病微创治疗中的地位越来越高.EUS-FNA与注射技术、EUS-CPN、EUS介导放射粒子植入术和内镜超声引导下胰腺假性囊肿穿刺引流等治疗技术会逐步推广应用,成为继ERCP内镜治疗后胰腺疾病微创治疗的重要方法.

Endoscopic ultrasonography and endoscopic treatment of pancreatic diseases

The principle of Endoscopic Ultrasonography (EUS) is similar to abdominal ultrasonography. The difference between them is the installment of a high-frequency ultrasound miniature probe at the tip of the endoscope for real-time ultrasound scanning. The pancreas is a retroperitoneal organ. The insertion of the ultrasonic endoscope into the stomach and duodenum can clearly demonstrate the structure of the pancreas on ultrasound scanning. With the extensive application of EUS and development of endoscopic accessories, EUS is becoming more important and it plays an important role in the minimally invasive treatment of pancreatic diseases. EUS-FNA and injection technique, EUS-CPN,EUS-guided radiation seed implantation, endoscopic ultrasound-guided puncture and drainage of pancreatic pseudocyst broaden the application of EUS techniques. EUS will become another important minimally invasive endoscopic treatment for pancreatic diseases following ERCP.
