Healthy volunteers help map normal pancreatic fluid

This study aims to collect and analyze pancreatic fluid from 24 healthy adults after giving them a synthetic hormone called secretin. The secretin is injected during an endoscopic ultrasound to stimulate the pancreas to release fluid, which is then collected from the duodenum. Researchers will measure levels of bicarbonate, sodium, potassium, and chloride to better understand normal pancreatic fluid composition. This knowledge may help improve diagnosis and monitoring of pancreatic diseases like chronic pancreatitis.
