Q

What should you look for on examination of the hands?

A

Colour – palmar pallor (anaemia) vs erythema (liver disease/pregnancy)
Temperature

Q

What should you examine the chest for?

A

Spider naevi
Gynaecomastia and loss of body hair (due to elevated circulating oestrogens in liver cirrhosis or with digoxin or spironolactone use)

Q

What should you examine the abdomen for?

A

Firstly, patient must be lowered to flat and only use one pillow, if possible
Skin – scars, loose folds? (sudden loss) striae? (sudden gain) bruising (Cullen’s/Grey-Turners in pancreatitis/AAA rupture
Shape and symmetry, muscle wasting
Movement during breathing (less diaphragmatic breathing if peritonitis)
Visible masses, peristalsis, aortic pulsation etc
Distended veins - paraumbilical = caput medusae in portal HTN
Stomas - colostomy (LIF), ileostomy (RIF), urostomy (RIF) - attachment site, contents
5 F’s of distension

Q

What should you look for on general palpation of the abdomen?

A

Ask about pain, start opposite place, observe face throughout and mentally visualise underlying anatomy whilst palpating
Palpate the 9 regions of the abdomen wall gently and systematically whilst observing the patients face for signs of discomfort - feel for areas of tenderness, guarding, rigidity etc
Repeat the palpation using deeper palpation with 2 hands – feel for any masses – size, surface, shape, edge, consistency, tenderness?

Q

How do you palpate the liver?

A

Start palpating in the right iliac fossa (as hepatomegaly can reach down that far), ask the patient to take a deep breath in whilst you use the edge of your hand to palpate deeply and find any descending edge of the liver
Patient asked then to breathe out whilst you place your hand slightly closer to the costal margin, repeat until edge of liver found or not (in the healthy, won’t normally be easy to palpate, neither will the gall bladder)

Any tenderness on liver palpation - ?hepatitis
Pulsatile - tricuspid regurgitation

Q

How do you palpate the spleen?

A

Not normally palpable in the healthy patient
Palpation should begin in the right iliac fossa and advance towards the left costal margin (as this is the direction the spleen enlarges in), palpate in the same way as when looking for the liver

Q

How do you palpate the kidneys?

A

Examined by ballottement – anterior hand presses deeply to the left of the rectus sheath in the upper quadrant of the abdomen, posterior hand placed in the costovertebral angle and should be used to lift the kidney towards the anterior hand
Feel for masses – number, size, shape, consistency, pain etc

Q

How do you palpate the bladder?

A

Palpate down from umbilicus to suprapubic region, if full – pressure will make patient want to urinate

Q

How do you palpate the abdominal aorta?

A

Use the first two fingers of both hands to press in deeply, just superior to the umbilicus
Normally should be pulsatile but if is expansile i.e. pushes your fingers away then it suggests aneurysmal dilatation

Q

How do you percuss the abdomen?

A

Percuss in the same way as you palpate ie from the right iliac fossa upwards
Liver - percuss up from RIF and down from R chest - should sound from resonant to dull to resonant (from below to above)
Spleen – a with liver; percuss the lowest intercosal space (8/9th) in the left anterior axillary line when patient is in full inspiration and full expiration - the positive sign for splenomegaly is resonant on expiration and dull on inspiration
Bladder – dull note if enlarged

Q

How do you percuss for ascites?

A

Test for shifting dullness – percuss from the centre towards the left flank, if a dull note is heard – place your finger on the spot and roll the patient towards you, wait 10 seconds for fluid to redistribute
If note becomes resonant, percuss back towards the umbilicus until the notes becomes dull again

Q

What do you listen for on auscultation?

A
Are bowel sounds present and normal? Tinkling – obstruction, absent – ileus/peritonitis 
Femoral bruits (slightly higher than the level of the umbilicus and on either side, use the bell of the stethoscope) and aortic bruits
17
Q

How do you finish the examination?

A
(state you would perform ISHRUG) 
Inguinal lymph node examination
Stool sample
Hernial orifices (femoral and inguinal)
Rectal examination
Urine analysis
Genitalia 

+ BP + palpation/auscultation of femoral pulses

18
Q

What may cause distended veins (on the abdomen)?

A

IVC obstruction or portal HTN

19
Q

How do you determine whether a mass is intra-abdominal?

A

Ask the patient to raise their head and shoulders off the pillow
Masses within the abdominal wall become more prominent when the recti are contracted whereas intra-abdominal masses become less prominent

20
Q

What is a succession splash?

A

Shake the stomach briskly from side to side whilst listening for a sloshing sound, indicates stomach distension

21
Q

What is Courvoisier’s Law?

A

In the presence of a palpable and non-tender gall bladder (not normally palpable), jaundice is NOT likely to be due to gallstones

One of the most likely differentials is pancreatic malignancy (but not pathognomonic)

22
Q

What is Murphy’s sign?

A

Inspiratory arrest when hands placed over right costal margin in the mid clavicular line, indicating an inflamed gallbladder. Also needs to be repeated on the other side – a positive test overall requires no inspiratory arrest on the left

23
Q

What are the names of different abdominal scars and what procedures do they reflect?

A
