The intraductal secretin test: an adjunct to ERCP

Abstract

The intraductal secretin test is an important diagnostic study. It enables the physician to determine the pancreatic secretory function in patients with known pancreatitis and to confirm the diagnosis of pancreatitis in many patients with indeterminate upper abdominal pain in whom ERCP and other diagnostic studies are normal. The IDST also provides the endoscopist and biochemist a new means to establish discriminating tests in differential diagnosis of pancreatic cancer and pancreatitis and to study the physiology of pancreatic secretion.
