    Abstract:
    The diagnostic value of the estimation of faecal elastase-1, the new noninvasive direct pancreatic function test was evaluated in a total of 35 patients. Twenty one patients were diagnosed with chronic pancreatitis and categorized according to grades of exocrine pancreatic insufficiency based on the Lundh test, 14 patients in the control group had gastrointestinal disorders. Faecal elastase 1 was measured by ELISA method. The sensitivity, specificity, positive and negative predictive value and diagnostic accuracy of elastase determination was 71.4%, 92.8%, 88.2%, 81.2% and 83.7%, respectively in chronic pancreatitis. In the severe exocrine pancreas insufficiency group (n = 14), the sensitivity was 85.7%, while in the group with mild insufficiency (n = 7) the sensitivity was only 42.8%. The determination of faecal elastase is useful in the diagnosis of severe exocrine pancreas insufficiency, but it is not sensitive enough in the mild form of the disease.
