![Acute Pancreatitis: Pathogenesis and Clinical Findings
Authors: Yan Yu Reviewers: Laura Craig Noriyah AlAwadhi Ryan Brenneis Maitreyi Raman* * MD at time of publication
Associated signs due to intra- abdominal hemorrhage from an unknown mechanism (classically associated with pancreatitis, but happens in <1% of cases):
Note:
It is not enough to just diagnose “acute pancreatitis”. Full management requires determining underlying etiology with further work-up.
Alcohol
↑ Toxic metabolites within pancreas and Spincter of Oddi Spasms
Gallstones
Migration to common bile duct blocks Sphincter of Oddi
Hypertriglyceridemia
Unknown
mechanism (rare)
Idiopathic
Further investigations:
CBC: Cell counts elevated, due to sever hypovolemia
Serum [Lipase]: Gold Standard Diagnostic Test; rupture of pancreatic cells releases lipase into circulation
Pancreatic secretions back up, ↑ pressure within pancreas
Hypercalcemia (Rare; Ca2+ depositions in bile ducts block outflow of pancreatic secretions)
Since pancreas is retroperitoneal, somatic
nerves in the parietal peritoneum are directly stimulated
Inflammation triggers cytokine release
Inflamed pancreas irritates adjacent intestines, causing ileus
Inflamed, more permeable blood vessels leak fluid into pancreas
• •
Cullen’s sign (bruising in peri-umbilical region) Grey-Turner’s sign (bruises along both flanks)
Sudden, severe epigastric pain (with peritoneal signs), radiates to the center of the back
Fever, nausea/vomiting
(general signs of inflammation)
Diminished bowel sounds Profound dehydration
(flat JVP, hypotension, tachycardia, oliguria) – may happen, not always
1. Pressure compresses pancreatic blood vessels, causing tissue ischemia.
2. Activation of inactive proteases (zymogens) digesting pancreatic tissue
Necrosis (death) of pancreatic cells
Inflammation self- perpetuates
Massive systemic inflammatory response
2 main complications, usually detected on CT;
may happen, but not always
1. Pancreatic pseudocyst (enlargement of the
pancreas due to fluid accumulation)
2. Pancreatic necrosis/abscesses (death of a part of the pancreas)
