A study indeed found that a complete resection with negative margins can be

achieved in almost half of patients with suspicion of locoregional PC, when state-of-the-art preoperative imaging was used (8). Pancreatic tumors have always represented a complex dilemma for clinicians and diagnostic imaging and, currently, there is no consensus on the optimal preoperative imaging modality for diagnosis and staging assessment of patients with suspected or proved locoregional PC. This brought us during the years to a complex range of diagnostic proposals. Three steps are crucial in clinical practice: first you must find the lesion (detection), secondly you must make a differential diagnosis between benign and malignant #Sepantronium Bromide cell line keyword# pancreatic masses and once the diagnosis of PC is established you need the most accurate preoperative staging to select patients that can benefit from curative Inhibitors,research,lifescience,medical resections. Modern imaging techniques such as transabdominal ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI) and EUS

are less invasive and less costly than surgery. For years EUS has been claimed to be the best currently Inhibitors,research,lifescience,medical available technique for imaging the pancreas, but in the last ten years we have witnessed tumultuous and galloping technological improvements of the radiological and nuclear imaging techniques. Taking into account the rapid increase in the sensitivity and accuracy of these new technologies, in a narrative review we analyzed current and future perspectives

Inhibitors,research,lifescience,medical of EUS in the mangement of PC. Other important and challenging tasks of pancreatic EUS are represented by: (I) the differential diagnosis of solid pancreatic masses (auto-immune pancreatitis, chronic pancreatitis, solid-cystic dystrophy of the duodenal wall, neuroendocrine tumor, pancreatic metastasis); (II) differential diagnosis and surveillance of pancreatic cystic lesions; (III) Inhibitors,research,lifescience,medical detection, diagnosis and staging of neuroendocrine tumors (NETs) of the duodenopancreatic area; (IV) diagnosis of parenchymal and ductal changes of chronic pancreatitis (CP); (V) the setting of idiopathic acute pancreatitis (AP) in order to define an aetiology, to identify patients that can take advantage of an endoscopic treatment (endoscopic retrograde cholangiopancreatography or ERCP) and to predict severity of the AP. To identify all publications considered appropriate to discuss this issue, a Florfenicol MEDLINE search of all studies published from 1965 to 2012 was conducted. The final date of the MEDLINE search was November 25, 2012. The following medical subject headings were used: pancreatic cancer, pancreatic cyst, neuroendocrine tumor, endoscopic ultrasound, echoendoscopy, EUS, fine-needle aspiration, and FNA. The search was also performed using reference lists from published articles. The titles of these publications and their abstracts were scanned in order to eliminate duplicates and irrelevant articles.
