1. Disorders of the PancreasModule 2
2. Disorders of the Pancreas Acute Pancreatitis
Chronic Pancreatitis
Pancreatic Cancer
3. Acute Pancreatitis Acute inflammatory process of the pancreas
Degree of inflammation varies from mild edema (edematous pancreatitis) to hemorrhagic necrosis (Necrotizing pancreatizing)
Most common middle age
Men > women
Can be life threatening
4. Acute Pancreatitis—Etiology More common
Biliary tract disease
Alcoholism
Less common
Trauma (Post surgical, injury)
Viral infections
Duodenal conditions
Cystic fibrosis
Kaposi’s sarcoma
Oral contraceptives
Medications-steroids, thiazide diuretics, NSAID’s
Metabolic disorders
Eating disorders
Complication of ERCP
Idiopathic
5. Acute PancreatitisPathophysiology Believed to be autodigestion of pancreatic cells
Injury occurs, enzymes released
Trypsinogen normally enters small intestine and activated to trypsin
In pancreatitis, trypsin stays in pancreas, can digest pancreas
6. Acute PancreatitisClinical Manifestations Abdominal pain (LUQ or midepigastrum)
Pain radiates to back, sudden onset
Described as severe, deep piercing pain
Aggravated by eating
Not relieved by vomiting
7. Acute PancreatitisClinical Manifestations Cardiovascular
Hypotension
Tachycardia
Shock
Hypovolemia
Respiratory
Cyanosis
Dyspnea
Crackles in lungs
Hemovascular/Immune
Fever
Leukocytosis
8. Acute Pancreatitis-Clinical manifestations GI
Bowel sounds decreased/absent
Ileus may be present
N/V
9. Acute Pancreatitis-Clinical Manifestations Integumentary
May have flushing
Jaundice
Grey Turner spots
Eccymosis of the flanks
Bluish flank discoloration
Cullen’s Sign
Bluish discoloration of the periumbilical area
10. Acute Pancreatitis—Complications Pseudocyst
Cavity continuous with or surrounding the outside of the pancreas
Pseudocyst is filled with necrotic products and liquid secretions (Enzymes)
Encapsulation can occur
Abdominal pain, N/V, anorexia, fever, leukocytosis occurs
May resolve spontaneously or may rupture
Treatment-internal drainage with anastamosis
11. Acute Pancreatitis—Complications Pancreatic abscess
Large fluid filled cavity within pancreas
Abdominal pain, N/V, anorexia, fever, leukocytosis occurs
Can infect or perforate adjacent organs
Client needs surgical intervention
12. Acute Pancreatitis—Complications Systemic
Pulmonary (Pleural effusion, atelectasis)
Cardiovascular (Shock)
Hypocalcemia indicates severe disease-monitor for tetany (Cvostek’s/Trousseau’s)
13. Acute PancreatitisDiagnostic Studies Serum amylase
More commonly used for diagnosis
Greater than 200 u/l is diagnostic
Elevates earlier
Remains elevated for 24-72 hrs
Other disorders can elevate amylase
Serum Lipase
Urine amylase may be elevated
Renal-amylase-creatinine clearance test
14. Acute PancreatitisDiagnostic Studies Hyperglycemia
Hyperlipidemia
Hypocalcemia
Endoscopic US
CT/MRI
ERCP-Diagnostic test for gallstones, pancreatic cysts, abscesses
15. Acute Pancreatitis—Treatment Objectives
Pain management
Prevent shock
Fluid and electrolyte balance
Prevention of infection/Complications
Remove cause
16. Acute Pancreatitis—Treatment Pain management (Morphine)
Hydration
Antispasmotic
Replace volume (LR) or blood products if needed
NPO/TPN
NGT
Dialysis??
Antibiotics
Surgery-ERCP with sphincterectomy
17. Chronic Pancreatitis Abdominal pain (chronic, recurrent)
May have constant pain or may diminish as fibrosis develops
Heavy knawing feeling
Not relieved with food or antacids
18. Chronic PancreatitisClinical manifestations Symptoms of pancreatic insufficiency
Malabsorption with weight loss
Constipation
Mild jaundice with dark urine
Steatorrhea
Diabetes mellitus
Frothy urine and stool
19. Chronic PancreatitisDiagnostic Studies Amylase/Lipase may be slightly elevated or normal
Increased serum bilirubin
Increased Sed rate
Secretin stimulation test
Hyperglycemia
Stool for fat analysis
X-ray-fibrois and calcification
20. Chronic PancreatitisDiagnostic Studies Endoscopic US
CT/MRI
ERCP
21. Chronic Pancreatitis If exacerbation, treat as for acute pancreatitis
Bland, low fat, high carb diet later
Control diabetes
Pancreatic enzymes (Viokase, Cotazym)
Bile salts
H2 blockers
Proton pump inhibitors
Surgery
Roux- en Y
Choledochojejunostomy
Avoid ETOH
22. Pancreatic Cancer Most are adenocarcinoma, occur in head of pancreas
Prognosis usually poor
Etiology
Unknown
Risk factors
Cigarettes
Chemical exposure
High fat diet
Diabetes
Chronic pancreatitis
23. Pancreatic Cancer—Clinical Manifestations Upper abdominal pain (dull, aching to extreme unrelenting (later)
Anorexia
Rapid weight loss
Jaundice
24. Pancreatic Cancer—Diagnostic Studies CT
ERCP-gold standard
Tumor markers
CEA, more specific for colon cancer, less specific for pancreatic cancer
25. Pancreatic Cancer—Treatment Surgery
Whipple’s procedure (Radical pancreaticduodenectomy)
Total pancreatectomy
Radiation-Usually palliative
