Abstract:
Despite lack of evidence, use of a stylet during EUS-FNA is believed to improve quality and diagnostic yield of specimens. Use of a stylet is time consuming and increases cost of the needle. Recent pilot studies have suggested that use of a stylet does not impact diagnostic yield of malignancy.
