Applications of endoscopic ultrasonography in pancreatic cancer.
BACKGROUND Accurate staging of pancreatic cancer is essential for surgical planning and for identification of locally advanced and metastatic disease that is incurable by surgery. Advances in endoscopic sonography (EUS), computed tomography (CT), and positron emission tomography have improved the accuracy of staging and reduced the number of incomplete surgical resections. Tissue acquisition is...
متن کاملContrast-Enhanced Endoscopic Ultrasonography for Pancreatic Tumors
OBJECTIVES To investigate the usefulness of contrast-enhanced endoscopic ultrasonography (CE-EUS) for histological differentiation of pancreatic tumors. METHODS CE-EUS was performed for consecutive patients having a pancreatic solid lesion, and tumors were classified into three vascular patterns (hypervascular, isovascular, and hypovascular) at two time phases (early-phase and late-phase). Co...
متن کاملTherapeutic endoscopic ultrasonography in pancreatic malignancy. Is the ERCP passè?
Endoscopic biliary stenting is the most common method of treating obstructive jaundice. But, in about 3-12% of cases, selective cannulation of the major papilla fails and surgery or percutaneous biliary drainage is required. But, percutaneous drainage requires dilated intrahepatic biliary ducts, and the rate of complications reaches 20%. including cases of peritoneal bleeding. A new technique o...
متن کاملEndoscopic ultrasonography in suspected pancreatic malignancy and indecisive CT.
BACKGROUND In the assessment of patients with a clinical suspicion of malignant pancreatic disease, computed tomography (CT) findings are sometimes negative or inconclusive. AIMS To determine whether endoscopic ultrasonography (EUS) with or without fine needle aspiration (EUS÷FNA) was conclusive in patients with a clinical suspicion of pancreatic malignancy, in whom CT scan was negative or in...
متن کاملContrast-Enhanced Harmonic Endoscopic Ultrasonography in Pancreatic Diseases
Endoscopic ultrasonography (EUS) is the most sensitive imaging method for diagnosis of pancreatic tumors. However, it still has limits in the differentiation between pancreatic cancers and inflammatory tumor-like masses. A novel technology, contrast-enhanced harmonic EUS (CH-EUS), has been developed recently. It can visualize both parenchymal perfusion and microvasculature in pancreas without D...
