Signs and Symptoms of Acute Pancreatitis
The cardinal presenting feature of acute pancreatitis is acute onset of persistent, severe epigastric pain that often radiates to the back, typically severe enough to prompt urgent medical attention. 1, 2
Clinical Presentation
Primary Symptom
- Abdominal pain: Acute onset of persistent, severe upper abdominal (epigastric) pain radiating to the back is the hallmark symptom 1, 2, 3
- Pain onset may be related to a recent alcohol binge or consumption of a rich, fatty meal 4
- The pain is characteristically severe enough that patients seek urgent medical attention 4
Associated Signs and Symptoms
General appearance and vital signs:
- Patient may appear unwell or distressed 4
- Tachycardia (rapid heart rate) 4
- Exquisite tenderness in the upper abdomen on examination 4
Gastrointestinal symptoms:
- Nausea (requiring management alongside pain) 1
Severity-Dependent Manifestations
In severe cases, patients may present with:
- Signs of organ failure (cardiovascular, respiratory, and/or renal) 1
- Systemic inflammatory response syndrome (SIRS) 1
- Unexplained multiorgan failure 3
Diagnostic Criteria
The diagnosis requires at least TWO of the following three criteria: 2, 3, 5
- Abdominal pain consistent with acute pancreatitis (as described above)
- Serum amylase and/or lipase ≥3 times the upper limit of normal
- Characteristic findings on abdominal imaging (ultrasound, CT, or MRI)
Important Clinical Caveat
While elevated pancreatic enzymes are typical, normal lipase levels should not exclude the diagnosis of acute pancreatitis if clinical presentation and imaging are consistent with the disease 6. In atypical presentations with normal enzyme levels, imaging becomes essential for diagnosis 6.
Physical Examination Findings
The key finding on physical examination is exquisite tenderness in the upper abdomen, particularly the epigastric region 4. The severity of tenderness often correlates with the severity of the inflammatory process.
