Acute Pancreatitis: Risk Stratification

Which of the following is not a commonly used prognostic indicator for acute pancreatitis?

A. Hematocrit on admission
B. Gallstones in the common bile duct on imaging
C. BUN on admission
D. Pleural effusion on CXR

Answer: B

There are several scoring systems used to risk stratify patients with acute pancreatitis. These include the Ranson, Glasgow, APACHE, and BISAP scores. Elevated hematocrit and BUN levels on admission are often a result of hemoconcentration and are important prognostic indicators for several scoring systems. In addition, the presence of pleural effusion, which can lead to oxygen desaturation, is an important prognostic indicator in acute pancreatitis. The presence of a common bile duct stone is not a prognostic indicator.
