About this trial
The purpose of this research is to compare the amount and quality of tissue obtained by EUS-FNB when the device is flushed with an anticoagulant or "blood thinner" vs. saline a salt water solution as well as the use of a microsieve in order for the doctor to look at the tissue to check the acceptability of the specimens before sending for analysis.
You will be randomly assigned (like a flip of a coin) to have either the blood thinner or the salt water solution placed within the needle being used to sample your abdominal tumor and to have either a sieve used or not.
You will be one of 42 participants enrolled in this data collection study which includes 1 sites in the United States.
