4 Feb 2016 Indications for EUS-guided fine-needle aspiration (EUS-FNA) include biopsy of mucosal and submucosal lesions in which prior conventional endoscopic biopsies have been nondiagnostic. The procedure is most commonly used to sample peri-intestinal structures such as lymph nodes and masses in the
This procedure is particularly important, as subtyping assessed by EUS-FNA does not always correlate with excisional biopsy results, and it is well-known that lymphomas can respond partially to different chemotherapies although a particular
Endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNA) is currently performed on a routine basis at many endoscopic centers and it is evident that this procedure has a major impact on the therapeutic management of patients by obtaining a definite tissue diagnosis from lesions outlined by endosonography.
10 Jun 2015 EUS guided approaches include transmural drainage (hepaticogastrostomy or choledochoduodenostomy), a rendezvous procedure or an antegrade approach[61]. EUS guided transluminal drainage (EUS-TLD) is achieved by bile duct puncture from the stomach or the duodenum using EUS-FNA needle.
22 Dec 2014 Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is a safe and complimentary investigation to CT/MRI imaging. The major advantage FNA or histological diagnosis at surgery or posttherapeutic endoscopy procedure (post EUS) was taken as the gold standard for final diagnosis. The final
7 Mar 2012 EUS-Guided Fine Needle Aspiration (EUS-FNA): Indications, Accuracy, and Technique. Although EUS is a very sensitive imaging modality, its ability to differentiate benign inflammatory and malignant pancreatic masses is low. The specificity is only about 75% [10]. The specificity can be increased to 100%

this technology depends, however, on effective collaboration between the cytopathologist and endoscopist and the willing- ness of the cytopathologist to have an integral role in patient management. Since this technique is being used increasingly in the United States and other parts of the world, the EUS- guided FNA biopsy
15 Jan 2015 Background: Endoscopic ultrasound–guided fine needle aspiration cytology (EUS-FNAC) is currently the most commonly used procedure for obtaining cytologic specimens of the pancreas. It is accurate, minimally invasive, safe and cost-effective. However, there is discrepancy between cytological and
