摘要

Endoscopic ultrasound(EUS)-guided fine needle aspiration with or without biopsy(FNA/FNB)are the primary diagnostic tools for gastrointestinal submucosal tumors.EUS-guided fine needle aspiration(EUS-FNA)is considered a first line diagnostic method for the characterization of pancreatic and upper gastrointestinal lesions,since it allows for the direct visualization of the collection of specimens for cytopathologic analysis.EUSFNA is most effective and accurate when immediate cytologic assessment is permitted by the presence of a cytopathologist on site.Unfortunately,the accuracy and thus the diagnostic yield of collected specimens suffer without this immediate analysis.Recently,a EUS-FNB needle capable of obtaining core samples(fine needle biopsy,FNB)has been developed and has shown promising results.This new tool adds a new dimension to the diagnostic and therapeutic utility of this technique.The aim of the present review is to compare the efficacy of EUS-FNA to that afforded by EUS-FNB in the characterization of pancreatic masses and of upper and lower gastrointestinal submucosal tumors.
