The Predictivity of Serum Biochemical Markers in Acute Biliary Pancreatitis

Abstract EN

Background and Aim.

There are no accurate methods of differentiating acute biliary pancreatitis.

Obstructions of biliary ducts, idiopathic pancreatitis may be related with biliary origin which needs identification for acute treatment.

We searched for the predictivity of biochemical markers in early acute biliary pancreatitis.

Patients and Methods.

Serum levels of AST (Aspartate Transaminase),ALT (Alanine Transaminase), ALP (Alkaline Phosphatase), GGT (Gamma Glutamyl Transferase), total bilirubin, direct bilirubin, LDH (Lactate Dehydrogenase), amylase, lipase, CRP (C-Reactive Protein) and WBC (White Blood Cell) were measured in 157 patients with acute pancreatitis.

Biliary and nonbiliary pancreatitis were differentiated by Magnetic Resonance Cholangiopancreatography (MRCP), Endoscopic Retrograde Cholangiopancreatography (ERCP), Intraoperative Cholangiopancreatography (IOC).

Cut-off points of admission biochemical markers with sensitivity, specifity, positive predictive value and negative predictive value were determined after identification of significant variables.

Receiver Operator Curves were plotted for each biochemical marker.

Results.

Serum Alkaline Phosphatase, total bilirubin, direct bilirubin, amylase and lipase levels were significantly higher in biliary pancreatitis with a positive predictive value of 80.8%, 83.9%, 81.6%, 78.8%, 79.7%.

Conclusion.

Increased Alkaline Phosphatase,total bilirubin, direct bilirubin, amylase and lipase levels may be used in prediction of biliary pancreatitis.
