| 摘 要： | EUS is the most sensitive imaging procedure for the detection of small solid pancreatic masses and is accurate in determining vascular invasion of the portal venous system. Even compared to the new CT-techniques EUS provides excellent results in preoperative staging of solid pancreatic tumors. Compared to helical CT-techniques EUS is less accurate in detecting tumor involvement of superior mesenteric artery. EUS staging and EUS-guided FNA can be performed in a single-step procedure, to establish the diagnosis of cancer. There is no known negative impact of tumor cell seeding due to EUS-FNA. Without FNA EUS and additional methods are not able to reliably distinguish between inflammatory and malignant masses.
