Q

What investigation are carried out for chronic pancreatitis?

A

• FBC - normal
• U&Es - normal
• Glucose - elevated
• LFTs - may be deranged if there is an obstruction of the common bile duct –obstructive picture.
• Serology - elevated IgG4 in AI pancreatitis.
• USS Abdomen - percutaneous or endoscopic: Cavities, anatomical irregularities and calcification.
• AXR - pancreatic calcification
• CT Abdomen -pancreatic calcification, enlargement of the pancreas, ductal dilation, and/or vascular complications.
• ERCP/ MRCP - early: Duct dilation and the stumping of branches.
Late: Duct strictures with alternating dilations (chain of lakes appearance).
• Exocrine Function:
- Tests of pancreatic exocrine function:
- Faecal elastase –elevated
- Faecal fate –elevated
- Steatocrit –elevated
• Pancreatic biopsy - may be required for diagnosis: Increased CT, loss of acini, fibrosis and calcification.
Therapeutic Steroid Trial: Positive response in AI pancreatitis.

Q

What is the management for acute pancreatitis?

A

General:
• Dietary advice (low fat; medium chain triglycerides MCTs may be tried)
• Alcohol abstinence.

Chronic:
• Specialist pain clinic referral for chronic pain management.
• Diabetes treatment –insulin: long-acting; short-acting and mixed regimens.
• Pancreatic enzyme replacement: Creon; Pancrease; Lipase.

Interventional and Surgical:
• Endoscopic stenting of strictures may be beneficial.

Surgical:
• Indications: failure of medical management.
• Modified Puestow Procedure: Lateral pancreaticojejunal drainage.
• Whipple’s Pancreaticoduodenectomy: Resection
• Berger Procedure: Limited resection of the pancreatic head
• Frey Procedure: Combined opening of the pancreatic duct and revealing the head.
