Pancreatic Disease Flashcards
What is acute pancreatitis?
Acute inflammation of the pancreas characterised by upper abdominal pain and elevation of serum amylase to > 4x normal levels.
How does Acute Pancreatitis present?
1) Severe, constant upper abdominal pain which increases in intensity over 15-60 minutes and radiates to the back
2) Nausea and vomitting
3) Epigastric tenderness
What causes acute pancreatitis?
1) Gallstones
2) Alcohol
3) Post-ERCP
4) Idiopathic
What are the investigations of acute pancreatitis?
Blood tests:
- Raised amylase/lipase
- FBC (raised WBC, raised CRP)
- U&E’s (raised urea)
- Ca2+
- Glucose
- ABG’s
Imaging:
AXR/CXR
Abdominal USS
CT scan - contrast enhanced
How is severity of acute pancreatitis assessed?
Glasgow criteria - score >3 of the following criteria = Severe pancreatitis
- White cell count >15 x 109/l
- Blood glucose >10 mmol/l
- Blood urea >16mmol/l
- AST >200 iu/l
- LDH >600 iu/l
- Serum albumin <32 g/l
- Serum calcium <2.0 mmol/l
- Arterial PO2 <7.5 kPa
What is the general management of acute pancreatitis?
- Analgesia
- IV fluids
- Blood transfusion
- Monitor urine output
- Naso-gastric tube
- Oxygen
What are the surgical options for managing acute pancreatitis?
Pancreatic necrosis - CT guided aspiration with antibiotics and then possible surgery
Gallstones - Cholecystectomy
What is Chronic Pancreatitis?
Continuing inflammatory disease of the pancreas characterised by irreversible glandular destruction and typically causing pain and/or permanent loss of function
How does chronic pancreatitis present?
- Early disease is asymptomatic
- Abdominal pain
- Weight loss (protein malabsorption)
- Steatorrhoea (exocrine insufficiency causing malabsorption of fat)
- Diabetes (endocrine insufficiency)
What are the investigations for chronic pancreatitis?
- AXR (calcification of pancreas)
- Ultrasound (size of pancreas, cysts, duct diameter, tumours)
- CT
- Blood tests:
- Raised serum amylase
- Lowered albumin, Ca2+, Vit B12
- Raised LFT’s, PT and Glucose
How is chronic pancreatitis managed?
Pain control:
- avoid alcohol
- pancreatic enzyme supplements
- opiate analgesia (dihydrocodeine, pethidine)
- Coeliac plexus block
- referral to pain clinic/psychologist
- Endoscopic treatment of pancreatic duct stones and strictures
- Surgery in selected cases
How are the exocrine and endocrine insufficiencies managed in acute pancreatitis?
- Low-fat diet (30-40 g/day)
- Pancreatic enzyme supplements (eg. Creon, Pancrex); may need acid suppression to prevent hydrolysis in stomach
- Vitamin supplements usually not required
- Insulin for diabetes mellitus (oral hypoglycaemics usually ineffective)
