Etiology, Clinical Presentation, and Diagnosis
- Let’s head to the surgical emergency bay. Acute pancreatitis refers to acute autoduodenal digestion and inflammation of the pancreas. The two most common etiologies are Gallstones (getting stuck in the ampulla of Vater) and chronic Alcohol abuse.
- The patient presents with severe, boring, constant epigastric pain that radiates directly to the back. Crucially, the pain is relieved when the patient sits up and leans forward!
- To diagnose acute pancreatitis, you must meet 2 of the following 3 criteria: (1) acute onset severe epigastric pain; (2) serum amylase or lipase levels elevated at least 3 times the upper limit of normal; and (3) characteristic findings on CT scan.
Physical Examination Signs & Severity Stratification
- In severe, hemorrhagic pancreatitis, blood can leak from the retroperitoneum into the subcutaneous tissues.
- Look for Cullen's sign (bluish bruising around the umbilicus) and Grey Turner's sign (bruising along the flanks). These are ominous indicators of severe retroperitoneal bleeding!
- To estimate prognosis and mortality risks, clinicians use scoring systems like Ranson's Criteria (assessed at admission and evaluated again at 48 hours) or the APACHE II score.

Surgical Pearl: Serum Lipase is a much more sensitive and selective marker of acute pancreatitis than amylase, and its elevation remains high for several days, making it the preferred diagnostic test!
