Endoscopic ultrasound in the diagnosis of occult pancreatic head cancer.
Two consecutive female patients presented with progressive jaundice, epigastric pain and weight loss. Cross-sectional imaging with computer tomography and magnetic resonance imaging did not show any mass lesions whereas magnetic resonance cholangiopancreatography showed common bile duct strictures. Both patients were then referred for endosonographic evaluation. Endoscopic ultrasound showed occ...
متن کاملRole of endoscopic ultrasound in the diagnosis and staging of pancreatic cancer.
Endoscopic Ultrasound (EUS) is a relatively new modality. Its high resolution makes it possible to detect tumors of 5mm in diameter otherwise missed by other imaging modalities. It is more accurate than computerized tomography (CT) scan, Transabdominal Ultrasound (US) and Magnetic Resonance Imaging (MRI) in diagnosing pancreatic lesions, especially those less than 20mm in diameter. EUS can be u...
متن کاملMolecular Endoscopic Ultrasound for Diagnosis of Pancreatic Cancer
Endoscopic ultrasound-guided fine needle aspiration-biopsy is a safe and effective technique in diagnosing and staging of pancreatic ductal adenocarcinoma. However its predictive negative value does not exceed 50% to 60%. Unfortunately, the majority of pancreatic cancer patients have a metastatic and/or a locally advanced disease (i.e., not eligible for curative resection) which explains the li...
متن کاملVascularisation Pattern of Chronic Pancreatitis Compared with Pancreatic Carcinoma: Results from Contrast-Enhanced Endoscopic Ultrasound
Discriminating between focal chronic pancreatitis and pancreatic cancer is always a challenge in clinical medicine. Contrast-enhanced endoscopic ultrasound using Doppler techniques can uniquely reveal different vascularisation patterns in pancreatic tissue alterated by chronic inflammatory processes and even allows a discrimination from pancreatic cancer. This paper will describe the basics of ...
متن کاملEndoscopic Ultrasound-Guided Oncologic Therapy for Pancreatic Cancer
Since the development of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in the early 1990s, its application has been extended to various diseases. For pancreatic cancer, EUS-FNA can obtain specimens from the tumor itself with fewer complications than other methods. Interventional EUS enables various therapeutic options: local ablation, brachytherapy, placement of fiducial markers...
