AP is diagnosed when patients present with two of the following: upper abdominal pain, amylase and/or lipase elevation more than three times the upper limit of normal, and/or imaging consistent with AP [1]. However, upper abdominal pain is not specific for AP and the diagnostic value of pancreatic enzyme elevation in AP is not clear. There are many intra‐abdominal conditions that can result in lipase and amylase elevations that may be misdiagnosed as AP, including inflammatory bowel disease, mesenteric ischemia, perforated peptic ulcer, dissecting aortic aneurysm, bowel obstruction, biliary colic, and acute appendicitis [9]. Therefore, imaging can help to exclude alternative causes of abdominal pain and can confirm the diagnosis of AP, particularly in those with a high suspicion of AP based on risk factors and clinical presentation.
