Q

Why is it important to ask about previous vascular disease and cardiovascular risk factors?

A

A history of vascular disease increases the risk of mesenteric ischaemia and myocardial infarction

20
Q

Which two diseases that cause epigastric pain can be caused by drugs? Which drugs are associated with each of these diseases?

A 
- Peptic ulcer disease 
NSAIDs
Aspirin
Bisphosphonates
Steroids
- Acute pancreatitis 
Sodium valproate 
Thiazides 
Steroids
Azathioprine
21
Q

List some significant features of the social history.

A

Alcohol – excess can cause acute pancreatitis

Smoking – associated with peptic ulcer disease, MI and mesenteric ischaemia

22
Q

Describe the appearance of a peritonitic patient.

A

Patients lie completely still
Taking shallow breaths
Movement is painful

23
Q

How can acute pancreatitis lead to jaundice in the absence of gallstones?

A

Oedema of the head of an inflamed pancreas can obstruct the common bile duct

24
Q

Describe Grey-Turner’s and Cullen’s Signs. What are they signs of?

A

They are signs of severe pancreatitis
Cullen’s Sign – bruising/discolouration around the umbilicus
Grey-Turner’s Sign – bruising/discolouration on the flanks

25
Q

List signs of small bowel obstruction.

A

Abdominal distension
Tinkling bowel sounds
Absolute constipation

26
Q

What is Murphy’s sign?

A

A finger is placed just below the tip of the right 9th costal cartilage and the patient is asked to breathe in deeply
Inspiration is arrested when the inflamed gallbladder strikes the finger of the examiner
This is indicative of cholecystitis

27
Q

Which masses might you palpate for in the abdomen of a patient with epigastric pain?

A

AAA – central expansile and pulsatile mass

Check hernia orifices because a strangulated hernia could cause bowel obstruction

28
Q

List some important blood tests that you would perform in a patient with epigastric pain.

A 
FBC – check for raised WCC, anaemia, neutrophilia
CRP
Pancreatic Amylase and Lipase
Liver enzymes 
Albumin 
U&Es
Calcium
Glucose 
ABG
29
Q

Describe different patterns of derangement of liver enzymes and state what they indicate.

A

High AST + ALT (transaminitis) = liver pathology (e.g. hepatitis)
High ALP + GGT = biliary disease
Isolated raised GGT = alcoholic liver disease
High AST: ALT ratio (> 2:1) = alcoholic liver disease

30
Q

List some prognostic indicators in pancreatitis.

A

Neutrophilia
Albumin
Blood glucose

31
Q

Describe the time taken for serum amylase to rise and fall in a case of pancreatitis.

A

Rises within hours

Returns to normal after 3-5 days

32
Q

Why is it important to measure serum calcium in a patient with pancreatitis?

A

Hypercalcaemia – can cause pancreatiits
Hypocalcaemia – can result from severe pancreatitis (a process called saponification occurs where calcium binds to digested lipids)

33
Q

Why is it important to perform a VBG in a patient with epigastric pain?

A

Allows assessment of pH and lactate
pH will decrease and lactate will increase in conditions causing a severe inflammatory response (e.g. acute pancreatitic, peritonitis)
NOTE: this is because a systemic inflammatory response –> vasodilation –> hypoperfusion of tissues –> increase in anaerobic respiration –> lactic acidosis

34
Q

Which forms of imaging are useful in patients with epigastric pain?

A

Erect CXR
AXR
Ultrasound

35
Q

Which sign on erect CXR suggests that there has been a GI perforation?

A

Air under the diaphragm (pneumoperitoneum)

36
Q

Why might ultrasound be useful in investigating a patient with epigastric pain?

A

Allows visualisation of AAA

Allows visualisation of gallstone disease

37
Q

What is the downfall with the use of ultrasound to investigate AAAs?

A

It does not show whether the AAA is leaking/ruptured

A CT aortogram is required to confirm a leak

38
Q

List the causes of acute pancreatitis.

A 
GALLSTONES
ETHANOL
Trauma
Steroids
Mumps/HIV/Coxsackie
Autoimmune
Scorpion venom
Hypercalcaemia/ hyperlipidaemia/hypothermia
ERCP
Drugs (e.g. sodium valproate, thiazides)
39
Q

What are the two main scoring systems for pancreatitis?

A

Glasgow

Ranson

40
Q

With regards to the Glasgow scoring system, what score is considered severe pancreatitis?

A

3 and above

41
Q

Outline the management of acute pancreatitis.

A 
Assess ABC (NOTE: pancreatitis can cause ARDS)
IV fluids 
Oxygen 
Analgesia
Anti-emetics 
DVT prophylaxis 
Low-fat diet
42
Q

How can you reduce the recurrence of pancreatitis?

A

Cholecystectomy

Stop drinking alcohol

43
Q

Describe the two main tests for Helicobacter pylori.

A

1) Urease Breath Test – the patient is asked to swallow a sample of urea containing radio-labelled carbon. After 10-30 mins, the patients breath is tested and if the radio-labelled carbon is identified in the patient’s breath, it suggests that urease, produced by H. pylori, is present in the patient’s stomach
2) Campylobacter-like Organism (CLO) Test – a biopsy is taking from the patient’s stomach and placed on a medium containing urea and an indicator. If urease (produced by H. pylori) is present in the patient’s stomach, it will convert the urea to carbon dioxide (and other by-products) and cause a change in the colour of the indicator

44
Q

Describe the treatment of H. pylori.

A

Triple therapy – 2 x antibiotics + PPI

45
Q

What is non-ulcer dyspepsia?

A

Chronic epigastric pain with normal blood tests, normal OGD and normal biliary ultrasound (there is no organic cause for the pain)
