Nozik igna biopsiyasi (FNB)

Mar 26, 2017

Fine Needle Biopsy (FNB) is often done during EUS procedures of pancreatic and non-pancreatic lesions where the tip of the FNA needle is not optimal. Examples include, but are not limited to, autoimmune pancreatitis, submucosal lesions, lymphoma and some forms of pancreatic ductal adenocarcinoma (PDAC). Some prospective cohort studies (Kim et al and Dewit et al) have shown a significant improvement in diagnostic yield with FNB needles on nonpancreatic lesion and gastric subepithelial masses.
