[Use of the pancreolauryl test in the diagnosis of exocrine pancreatic insufficiency. Preliminary results].

The Pancreolauryl Test (PLT), a tubeless test used to study exocrine pancreatic function, was performed in 18 patients (8 healthy controls and 10 patients with suspected chronic pancreatitis) to evaluate its sensitivity and clinical applicability. The sensitivity rate of PLT was 75%, the specificity 85.7%, the predictive value of a positive test 60% and of a negative test 92.3%. The PLT proved to be a non invasive, easy to perform test; besides it was acceptable to the patients, without collateral effects.
