Intraductal Secretin Stimulation Test: What Is the Proper Collection Time?

If pancreatic duct entry incidentally occurs during the clinically scheduled ERCP and the pancreatic duct appears normal, an IDST will be performed for study purposes. An IDST consists of the administration of human secretin, after which pancreatic juice is collected intraductally. In this study, the fluid will be collected through continuous aspiration in 5 minute intervals for 30 minutes. Samples will be collected at 5, 10, 15, 20, 25, and 30 minutes after secretin administration (6 collections in total).
