Biliary scintigraphy in acute pancreatitis

A N Serafini, W Al-Sheikh, J S Barkin

    Radiology
    |August 1, 1982

    Summary

    99mTc-PIPIDA scintigraphy effectively differentiates biliary pancreatitis from nonbiliary pancreatitis. An abnormal biliary scan, combined with elevated amylase, strongly suggests biliary pancreatitis, while a normal scan largely rules it out.

    Area of Science:

    • Hepatobiliary imaging
    • Gastroenterology
    • Diagnostic nuclear medicine

    Background:

    • Biliary pancreatitis requires accurate differentiation from nonbiliary causes for appropriate management.
    • 99mTc-PIPIDA scintigraphy is a nuclear medicine technique used to assess hepatobiliary function.

    Purpose of the Study:

    • To evaluate the efficacy of 99mTc-PIPIDA scintigraphy in distinguishing between biliary and nonbiliary pancreatitis.

    Main Methods:

    • A prospective study involving 60 patients (40 with biliary pancreatitis, 20 with nonbiliary pancreatitis).
    • Scintigraphic scans were categorized based on gallbladder visualization and intestinal excretion times of 99mTc-PIPIDA.

    Main Results:

    • 95% of patients with nonbiliary pancreatitis had normal scans (19/20).

    Related Experiment Videos

  • 22.5% of patients with biliary pancreatitis showed normal scans (9/40).
  • Abnormal biliary scans correlated with biliary pancreatitis when amylase levels were elevated.

    • Conclusions:

    • Elevated amylase levels and abnormal 99mTc-PIPIDA biliary scans indicate biliary pancreatitis.
    • A normal 99mTc-PIPIDA scan is highly effective in excluding biliary pancreatitis.
