Pancreas Flashcards
What is acute pancreatitis
- Inflammation of the pancreas
- Pancreatic enzymes (amylase / lipase) attack the pancreatic tissue
Diagnosed clinically / by rise in amylase (>3 x normal) / CT scan
Why amylase not be raised in an acute exacerbation of chronic pancreatitis
the pancreas has lost it’s ability to produce the enzyme
What are the signs and smyptoms of acute pancreatitis
- Severe epigastric pain that radiates to the back
- nausea and vomting
- anorexia
Investigations for acute pancreatitis
- amylase
What is the glasgow score
Score that indicates the severity of acute pancreatitis
<2: mild
2: moderate
>2: severe
Consider intensive care intervention/review when score is >1
What is involved in the ‘Pancreas pneumonic’ for the glasgow score
P – Pa02 < 60 A – Age > 55 N – Neutrophils (WBC > 15) C – Calcium < 2 R – uRea >16 E – Enzymes (LDH > 600 or AST/ALT >200) A – Albumin < 32 S – Sugar (Glucose >10)
What are the complications of acute pancreatitis
Pancreatitic necrosis
Infection in necrotic areas
Pseudocysts
Chronic pancreatitis
What is the management of acute pancreatitis
Patients can become extremely sick very quickly
Escalate care according to Glascow score
Careful monitoring
IV fluids
Analgesia
Endoscopic drainage of large pseudocysts
Antibiotics only if evidence of infected pancreatic necrosis
Surgery to remove infected pancreatic necrosis
What is the most common type of cancer of the pancreas
90% are adenocarincomas of the pancreas head
Typically metastasize early to liver, then to peritoneum, lungs and bones
What is the incidence and prognosis of pancreatic cancer
Peak incidence in 70s and 80s
5 year survival is 25% for early disease
Average survival for advanced disease is around 6 months
What is the common presentation of pancreatic cancer
- Non-specific upper abdominal/back pain
- Painless obstructive jaundice
- Unintentional weight loss
- Pale stools (due to lack of bile)
- Steatorrhoea
- Dark urine (due to obstructive jaundice)
- Palpable mass in epigastric region
What is steatorrhoea
(greasy stools due to malabsorption due to lack of bile)
How do you diagnose pancreatic cancer
CA19-9 tumour marker (blood test) CT scan (including thorax, abdomen and pelvis for staging) Endoscopic ultrasound with biopsy
What is Courvoisier’s law
Painless jaundice plus a non-tender palpable gallbladder is pancreatic cancer until proven otherwise
What is a whipples procedure
Requires the patient the be in good baseline health
For tumour of head of pancreas with no spread
Involves removing head of pancreas, gallbladder, duodenum and pylorus
Modified Whipple’s involves leaving the pylorus, and has equal success rates to traditional Whipples
