EUS and/or EUS-guided FNA in patients with CT and/or magnetic resonance imaging findings of enlarged pancreatic head or dilated pancreatic duct with or without a dilated common bile duct
Abstract
Incidental findings of an enlarged head of pancreas (HOP) or dilated pancreatic duct (PD) with or without a dilated common bile duct (CBD) on CT or magnetic resonance imaging (MRI), in patients without obstructive jaundice, raise suspicion for a pancreatic neoplasm, but their clinical significance has not been established. To determine the prevalence of pancreatic neoplasm in this patient group. Retrospective analysis of a prospective database. Tertiary-care university hospital. Patients without obstructive jaundice at initial presentation, who underwent EUS and/or EUS-guided FNA (EUS-FNA) for an abnormal CT and/or MRI with an enlarged HOP (n = 67) or a PD with or without a dilated CBD (n = 43). The final diagnosis was based on definitive cytology, surgical pathology, and clinical follow-up. An EUS examination was performed by using a radial echoendoscopy followed by a linear echoendoscopy, if a focal pancreatic lesion was identified. Fine-needle aspirates were stained with Diff-Quik and Papanicolaou's methods, and were immediately assessed by an attending cytopathologist. (1) The prevalence of pancreatic neoplasms and (2) performance characteristics of EUS-FNA for identifying malignant neoplasm, in this patient group. In 110 s...Continue Reading

Cancer Incidence & Mortality
Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
Cancer Imaging
Imaging techniques, including CT and MR, have become essential to tumor detection, diagnosis, and monitoring. Here is the latest research on cancer imaging.
