Acute pancreatitis is a sudden inflammation of the pancreas, an organ that helps digest food. It's most often caused by gallstones or heavy alcohol use. This condition can cause severe abdominal pain and requires prompt medical attention to prevent serious complications.
Acute pancreatitis is a sudden inflammatory process of the pancreas characterized by premature activation of pancreatic enzymes within the gland, leading to autodigestion. Common etiologies include gallstones and alcohol abuse, with diagnosis relying on characteristic clinical presentation, elevated serum amylase and lipase levels, and characteristic imaging findings.
| Condition | Distinguishing Feature |
|---|---|
| Peptic Ulcer Disease (PUD) | Pain may be burning, relieved by food or antacids, and less likely to radiate to the back. Amylase/lipase typically normal unless perforation occurs. |
| Cholecystitis/Cholangitis | Pain is often in the right upper quadrant, associated with fever and jaundice. Ultrasound is key for gallbladder pathology. Pancreatic enzymes may be mildly elevated due to shared ductal system. |
| Bowel Obstruction | Pain is colicky, associated with distension, obstipation, and vomiting. Bowel sounds may be hyperactive initially then absent. Imaging shows dilated loops of bowel. |
| Myocardial Infarction (Inferior Wall) | Pain can mimic epigastric pain, but ECG and cardiac biomarkers are diagnostic. Amylase/lipase are normal. |
| Aortic Aneurysm Dissection | Sudden, severe tearing chest or back pain. May have pulse deficits. CT angiography is diagnostic. |
| Gastritis/Gastroenteritis | Pain is typically less severe and more diffuse, often associated with diarrhea. Pancreatic enzymes are normal. |
Management focuses on supportive care, including aggressive intravenous fluid resuscitation, pain control with analgesics, and nutritional support. Identifying and treating the underlying cause, such as cholecystectomy for gallstone pancreatitis, is crucial for preventing recurrence.
