A 62-year-old man with chronic pancreatitis; fecal elastase test shows significantly reduced levels; what does this indicate?

• A. Pancreatic exocrine insufficiency
• B. Pancreatic endocrine insufficiency
• C. Normal pancreatic function
• D. Pancreatic cancer

Answer: (A)

Fecal elastase reflects pancreatic exocrine function, meaning how well the pancreas is delivering digestive enzymes to the gut. In chronic pancreatitis, the pancreatic acinar cells that produce these enzymes are damaged, so enzyme output—and thus elastase found in stool—drops. A significantly reduced fecal elastase indicates pancreatic exocrine insufficiency, which leads to maldigestion and potential steatorrhea. Endocrine function (hormone production like insulin) is a different aspect and isn’t assessed by this test, and pancreatic cancer isn’t diagnosed by low elastase alone.
