Acute Pancreatitis: The Daily PANCE Blueprint
A 52-year-old woman presents to the emergency department with severe epigastric pain that began 8 hours ago after eating a large, fatty meal. She describes the pain as constant and "boring," rating it 8/10, radiating to her back, and improving when she sits upright and leans forward. She has vomited three times since the pain started. Her medical history includes gallstones and occasional binge drinking. Vital signs show: temperature 38.0°C (100.4°F), blood pressure 95/65 mm Hg, and heart rate 115/min. On examination, she has epigastric tenderness without peritoneal signs, and decreased breath sounds at the left lung base. Laboratory results show lipase 1200 U/L (normal <60 U/L). What is the most likely diagnosis?
A. Acute pancreatitis
B. Acute cholecystitis
C. Perforated gastric ulcer
D. Acute coronary syndrome
E. Acute mesenteric ischemia
Answer and topic summary
The answer is A. Acute pancreatitis
This patient’s presentation of severe epigastric pain radiating to the back with positional improvement when leaning forward, along with risk factors of gallstones and alcohol use, strongly suggests acute pancreatitis. The condition occurs when pancreatic enzymes inappropriately activate within the pancreas, leading to autodigestion and inflammation. Diagnosis is confirmed by the presence of at least two of three criteria: characteristic abdominal pain, elevated lipase or amylase >3 times upper limit of normal, and supportive imaging findings. Associated findings often include nausea/vomiting, tachycardia, hypotension, and left-sided pleural effusion. Treatment focuses on aggressive fluid resuscitation, pain management, bowel rest, and identifying and treating the underlying cause (typically gallstones or alcohol). Severe cases may require intensive care for monitoring of complications such as necrotizing pancreatitis or organ failure.
Incorrect answer explanations:
- Acute cholecystitis: Typically presents with right upper quadrant pain and Murphy’s sign, often associated with fatty food triggers but without significant lipase elevation.
- Perforated gastric ulcer: Usually presents with sudden, severe pain and board-like abdominal rigidity with peritoneal signs.
- Acute coronary syndrome: While can present with epigastric pain, typically has associated chest pressure, shortness of breath, and ECG changes.
- Acute mesenteric ischemia: Usually presents in elderly patients with severe pain out of proportion to examination findings and risk factors for thromboembolism.
