Introduction: Because pancreatic exocrine function testing methods are problematic, both imaging and functional tests are important in the diagnosis of chronic pancreatitis.
Aim: To evaluate the usefulness of ultrasonographic monitoring of the main pancreatic duct after a secretin test.
Methodology: A total of 70 subjects (30 control subjects, 26 patients with probable chronic pancreatitis, and 14 patients with definite chronic pancreatitis) were selected.
