    Area of Science:

    • Biochemistry
    • Gastroenterology
    • Clinical Diagnostics

    Background:

    • Pancreatic function tests are crucial for diagnosing exocrine pancreatic insufficiency.
    • Duodenal aspiration is a common method for collecting pancreatic fluid.
    • Accurate measurement of pancreatic enzymes, like lipase, is essential for reliable diagnosis.

    Purpose of the Study:

    • To describe a simple, inexpensive procedure for quantifying pancreatic lipase activity.
    • To evaluate the efficacy of this new method compared to existing assays.
    • To recommend the inclusion of pancreatic lipase assay in routine duodenal aspiration protocols.

    Main Methods:

    • The described method involves diluting samples with an albumin solution.
    • Incubation with a commercial substrate mixture for 2 hours.
    • Manual titration using a burette to determine lipase activity.

    Main Results:

    • The manual titration method yielded results comparable to the established pH-stat assay.
    • The procedure is noted for its simplicity and low cost.
    • Demonstrated reliability for clinical diagnostic use.

    Conclusions:

    • The developed procedure offers a viable and cost-effective way to measure pancreatic lipase.
    • Incorporating this pancreatic lipase assay into duodenal aspiration protocols can improve diagnostic accuracy.
    • This method provides a valuable tool for assessing pancreatic function.
