Fine-Needle Biopsy: Should This Be the First Choice in Endoscopic Ultrasound-Guided Tissue Acquisition?

Abstract: Endoscopic ultrasound (EUS)-guided tissue acquisition is an indispensable technique for the diagnosis of many diseases of the gastrointestinal tract and adjacent structures. EUS-guided fine-needle aspiration (EUS-FNA) is known for its high accuracy and low complication rate. However, the outcome of EUS-FNA highly depends on several factors such as the location and characteristics of the lesion, endosonographer's experience, technique of sampling and sample preparation, type and size of the needle used, and pre… Show more

“…[ 13 ] Therefore, EUS-guided tissue acquisition can be a useful diagnostic method when a core biopsy tissue is necessary for a pathological confirmation. [ 14 15 ] In the present case, based on the EUS-FNA cytology findings, other tumors demonstrating dispersed plasmacytoid cell patterns, such as pancreatic neuroendocrine tumor, melanoma, and lymphoma with plasmacytic differentiation, could be considered in the differential diagnosis. Additional immunostaining using the FNAB specimen was helpful in confirming the diagnosis.…”

“…Endoscopic ultrasonography (EUS)-guided fine-needle aspiration (FNA) with tissue acquisition plays a pivotal role in the diagnosis of different diseases of the gastrointestinal tract and adjacent structures[ 1 ] and is known as well for its high accuracy and low complication rate. [ 2 ] Moreover, EUS-FNA has proven to be helpful in obtaining tissue samples from mediastinal lesions.…”
