Study Notes
Chronic Pancreatitis Overview
- Chronic pancreatitis can be caused by obstructions like strictures, stones, or tumors in the pancreas, autoimmune factors, immune checkpoint inhibitor therapy, or idiopathic reasons
- It can be classified into type 1 (multisystem disease), type 2 (affects pancreas alone), and type 3 (a complication of immune checkpoint inhibitor therapy)
- Approximately 10-30% of chronic pancreatitis cases are idiopathic, with genetic factors predisposing nearly half of early-onset cases and a quarter of late-onset cases
- Genetic factors include variants in the CFTR, PSTI (SPINK1), CTRC, CPA1, UGT1A7, PRSS1, CLDN2, and TRPV6 genes
- Classification systems for chronic pancreatitis include TIGAR-O (Toxic-metabolic, Idiopathic, Genetic, Autoimmune, Recurrent and severe acute pancreatitis, or Obstructive) and M-ANNHEIM (pancreatitis with multiple risk factors)
- The SAPE (Sentinel Acute Pancreatitis Event) hypothesis explains the pathogenesis of chronic pancreatitis, linking it to a first acute pancreatitis event leading to inflammation and fibrosis
- Chronic pancreatitis is a self-perpetuating disease characterized by chronic or recurrent episodes of acute pancreatitis and ultimately by pancreatic insufficiency
- Over 80% of adults develop diabetes mellitus within 25 years after the clinical onset of chronic pancreatitis
- Clinical findings of chronic pancreatitis include persistent or recurrent epigastric and left upper quadrant pain, anorexia, nausea, vomiting, constipation, flatulence, weight loss, tenderness over the pancreas, mild muscle guarding, ileus, and steatorrhea
- Pain results from impaired inhibitory pain modulation by the CNS and may vary over time, with no correlation with disease duration or imaging findings
- Steatorrhea, indicated by bulky, foul, fatty stools, may occur late in the course of chronic pancreatitis
- Surgical intervention tailored to the cause of pain may resolve chronic pain in chronic pancreatitis
Diagnosis and Complications of Chronic Pancreatitis
- Serum amylase and lipase may be elevated during acute attacks, but normal values do not exclude the diagnosis.
- Elevated alkaline phosphatase and bilirubin levels can result from bile duct compression.
- Exocrine pancreatic insufficiency is confirmed by response to pancreatic enzyme supplements or secretin stimulation test.
- Vitamin B12 malabsorption is detectable in about 40% of patients, but clinical deficiency is rare.
- Genetic testing for major trypsinogen gene pathogenic variants is recommended in younger patients with unclear etiology.
- Imaging with CT or MRI is recommended for diagnosis, showing calcifications, ductal dilatation, and gland atrophy.
- Endoscopic ultrasonographic criteria for chronic pancreatitis diagnosis include hyperechoic foci with shadowing.
- ERCP is the most sensitive imaging study and may show dilated ducts, stones, strictures, or pseudocysts.
- Histology is the gold standard for diagnosis when imaging studies are inconclusive.
- Autoimmune pancreatitis has characteristic imaging features including diffuse enlargement, hypoattenuation, and irregular narrowing of the main pancreatic duct.
- The diagnosis of autoimmune pancreatitis in the United States is based on the HISORt criteria.
- Complications of chronic pancreatitis include opioid addiction, brittle diabetes, pseudocyst or abscess, liver and bile duct issues, exocrine insufficiency, malnutrition, osteoporosis, and peptic ulcer.
