Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a randomized study that will enroll patients scheduled for an endoscopic ultrasound biopsy of a pancreas lesion to be in the heparin or saline group during the procedure. The purpose of this study is to examine the effect of blood contamination, heparin priming of the fine needle biopsies, and pass number on tumor tissue quality in fine needle biopsies. The hypothesis for this study is that fine needle biopsy tissue quality of pancreatic masses decreases with increasing pass number due to blood contamination; this blood contamination can be ameliorated with priming of the needle with an anticoagulant such as heparin.
