lüll Role of endoscopic ultrasound in diagnosis and therapy of pancreatic adenocarcinoma Boujaoude JWorld J Gastroenterol 2007[Jul]; 13 (27): 3662-6Since its advent more than 20 years ago, endoscopic ultrasound (EUS) has undergone evolution from an experimental to a diagnostic instrument and is now established as a therapeutic tool for endoscopists. Endoscopic ultrasound cannot accurately distinguish benign from malignant changes in the primary lesion or lymph node on imaging alone. With the introduction of the curved linear array echoendoscope in the 1990s, the indications for EUS have expanded. The curved linear array echoendoscope enables the visualization of a needle as it exits from the biopsy channel in the same plane of ultrasound imaging in real time. This allows the endoscopist to perform a whole range of interventional applications ranging from fine needle aspiration (FNA) of lesions surrounding the gastrointestinal tract to celiac plexus block and drainage of pancreatic pseudocyst. This article reviews the current role of EUS and EUS-FNA in diagnosis, staging and interventional application of solid pancreatic cancer.|Adenocarcinoma/*diagnostic imaging/pathology/therapy[MESH]|Antineoplastic Agents/administration & dosage[MESH]|Autonomic Nerve Block/methods[MESH]|Biopsy, Fine-Needle/methods[MESH]|Catheter Ablation/methods[MESH]|Celiac Plexus[MESH]|Cholangiography/methods[MESH]|Diagnosis, Differential[MESH]|Drug Delivery Systems/methods[MESH]|Endoscopy, Digestive System/instrumentation/*methods[MESH]|Endosonography/instrumentation/*methods[MESH]|Humans[MESH]|Neoplasm Staging/methods[MESH]|Pancreatic Neoplasms/*diagnostic imaging/pathology/therapy[MESH]|Photochemotherapy/methods[MESH]|Predictive Value of Tests[MESH]|Sensitivity and Specificity[MESH]|Ultrasonography, Interventional/instrumentation/*methods[MESH] |
