Background
- Chronic imflammatory changes of the pancreas causing permanent structural damage
- Can be minimally symptomatic and presents with acute exacerbations.
- Can lead to both long term endocrine and exocrine dysfunction
Clinical Features[1][2]
- Pain
- Episodic (1wk) or constant
- Epigastric, radiating to back and left infrascapular region
- Associated with nausea/vomiting
- Improved with sitting up or leaning forward
- Steatorrhea/DM
- Late finding
- Requires >80-90% loss of exocrine and endocrine function
- Erythema ab igne
- Hyperpigmentation of upper abdomen
Differential Diagnosis
Epigastric Pain
- Gastroesophageal reflux disease (GERD)
- Peptic ulcer disease with or without perforation
- Gastritis
- Pancreatitis
- Gallbladder disease
- Myocardial Ischemia
- Splenic Infarctionenlargement/rupture/aneurysm
- Pericarditis/Myocarditis
- Aortic dissection
- Hepatitis
- Pyelonephritis
- Pneumonia
- Pyogenic liver abscess
- Fitz-Hugh-Curtis Syndrome
- Hepatomegaly due to CHF
- Bowel obstruction
- SMA syndrome
- Pulmonary embolism
- Bezoar
- Ingested foreign body
Evaluation
- Labs
- Imaging[3][4]
- Plain film: pancreatic calcifications (30%)
- CT: intraductal calcifications (insensitive for early disease)
- ERCP: gold standard
Management
- Lifestyle modifications (alcohol and tobacco cessation), dietary changes
- Pancreatic enzyme supplements
- Acid suppression (H2 antagonist, PPI)
- Analgesics (NSAIDs, opioids, pregabalin)
- Specialist referral for refractory pain
Disposition
