Comparison of FNB to EUS-CNB for Pancreatic Lesions
Sponsor: University of California, Davis
Summary
The primary aim of this study is to compare the tissue specimen quality and diagnostic accuracy of biopsies obtained with one puncture of a regular 22 FNB G needle and the motorized EUS CNB device of pancreatic lesions. The secondary aims are to compare the rate of blood contamination in the specimens obtained from biopsies of pancreatic lesions and the overall procedure duration. The hypothesis of this study is that the proportion of cases in which a single puncture of the lesion in question delivers adequate diagnostic tissue is higher with the motorized EUS CNB than with the 22 G FNB.

endoscopic ultrasound guided biopsy with core needle biopsy device
The EUS-CBD (Endodrill, Bibb Medical, Lund Sweden) differs from currently available needles (FNB) in that it obtains tissue by drilling into target lesions rather than puncturing them.
