TITLE
How to make EUS FNA a success?

ABSTRACT

EUS-fine needle aspiration (FNA) is a valuable, accurate and rapidly expanding diagnostic method, which can be applied to every tumor or tumorlike lesion of pancreas, left lobe of the liver, common bile duct, adrenal glands, gastrointestinal tract, and mediastinum. Combined conventional cytology and liquidbased cytology (LBC), particularly ThinPrep method are recommended. LBC is essential for paucicellular sampling such as fibrous, necrotic or cystic tumors and for ancillary techniques such as immunodetection. The French Society of Clinical Cytology study has demonstrated significantly lower rates of nonrepresentative samples and higher sensitivity for LBC than for conventional smears. A cell block preparation including tissue fragments and clotted blood in a gel matrix can routinely be used in every histopathology laboratory. This preparation is a complementary, histologic method of improving the diagnostic yield and accuracy of FNA, permitting multiple sections, special stains, and reliable immunohistochemichal techniques. Sampling and interpreting FNA require expertise. Close interaction between the clinician and the pathologist is an essential component of the success of FNA in the workup of deepseated lesions.
