The Cellularity Yield of Three Different 22-gauge FNA Needles

Completed · Not applicable

Conditions studied: Pancreatic or Peripancreatic Lesions, Lesions in the Esophagus, Stomach, Duodenum or Rectum, Mediastinal ( Chest) Masses, Enlarged Lymph Nodes

In brief

Obtaining a sample from a lesion in the gastrointestinal tract by endoscopic ultrasound (a flexible tube with a camera and small ultrasound machine at its end )requires the use of a needle for taking the sample from the lesion or what we call "Fine needle aspiration (FNA)". Currently, FNA is done by three commercially available needles. These needles are used routinely in our institution for FNA. The data regarding the safety and the successfulness of any of these needles are lacking. We sought to compare all three commercially available needles in a prospective manner.
