The present study investigates the efficacy of a new Endoultrasound guided fine needle biopsy (EUS-FNB) device (AquireTM Boston Scientific= AQUIRE®) for obtaining histological tissue cylinders in the diagnosis of solid pancreatic tumors, submucosal tumors of the upper gastrointestinal tract (esophagus, stomach, duodenum) and lymph node disease..
The AquireTM FNB device uses a triple point tip that is designed to maximize tissue capture and minimize fragmentation. The efficiency of the 22 Gauge needle is evaluated in a prospective single arm study. The material obtained will be collected for formalin fixation and analyzed by a pathologist blinded for the type of needle device.
