Detaljeret beskrivelse
Potential subjects will be identified based on the indication of a pancreatic cyst requiring EUS-FNA. The procedure will be performed as usual per standard protocol with EUS-FNA of the cyst. Once the fluid is aspirated, it will be measured and if the fluid volume is 2.25 mL or greater than the patient will be included in the study.
A micropipette will be used to ensure exact volumes are measured. The first 1 mL of cystic fluid will be sent to the lab for regular CEA analysis, per standard protocol. The remaining fluid, which would usually be discarded, will then be used for the study. The micropipette will be used to mix 0.75 mL of cyst fluid with 0.25 mL of normal saline (designated sample #2). Next, 0.5 mL of cyst fluid will be mixed with 0.5 mL of normal saline for the next study sample (designated sample #3). These two study samples will be sent to the lab separately using de-identified information, and these values will not be part of the patient's medical record and will not affect clinical management or decision-making. The study samples will be given a unique identifier that will not have any patient identification. The unique identifier will allow the study researchers to link the values to the correct patient by using a password protected program that cannot be accessed by the public.
This study will not require any additional patient participation, and will not impact the length of the procedure. The only additional time will be from the study researchers and the EUS technologists diluting the samples, which will not affect the procedure time itself. If a single patient has more than one cyst, each cyst can be included in the study separately. No additional photographs, videos or data other than the standard data for the procedure will be produced.
