Question 7

(GI) Step 7:

Answer 7

Inspection of the Abdomen - ask the patient to lie flat with one pillow and arms by their side

• -> scars from past surgery
• -> striae/stretchmarks (pregnancy; obesity)
• -> distension or masses
• -> collateral vessels around the umbilicus called caput medusae (occurs in cirrhosis of the liver with portal hypertension)
• -> distended abdo wall veins (obstruction of the IVC)

Question 8

(GI) Step 8:

Answer 8

Palpation of the abdomen- use your right hand; warm hands; dont hurt them

• -> LIGHTLY to identify tenderness, guarding, rigidity, obvious masses
• -> DEEPER to identify specific masses or organ enlargment

Question 9

(GI) Step 9:

Answer 9

Examination of the Liver
–> palpate the lower R quadrant with flat hand on abdomen and parallel to the costal margin

–> apply firm pressure with fingers to feel for liver edge that moves downwards with inspiration (its being pressed down by the diaphragm)

–> Move your hand 2cm towards costal margin during expiration; palpate all the way along the coastal margin especially towards the epigastrium. It is confirmed by ercussing the liver from the lower R quadrant up to the right costal margin (percussion will change from resonant to dull when you reach the liver edge

–> Is the liver firm? are there masses?

–> To identify the upper liver border, percuss from above in the mid clavicular line. Start at the 3rd rib and move down one intercostal space at a time.

–> The upper edge is usually at the level of the 6th rib/5th intercostal space.

–>Measure the span of the liver with a tape measure. The liver span is measured in the midclavicular line. Normal liver span is 12-13 cm

Question 10

(GI) Step 10:

Answer 10

Examination of the Spleen
–> palpate by positioning the right hand parallel to the costal margin, commencing at the right lower quadrant.

–> palpate as the patient inspires

–> move hand towards costal margin two cm at a time during expiration (also check along costal margin)

–> roll the patient 45 degrees towards you and palpate again on inspiration

–> position your left hand posterolaterally, applying counter pressure. THis allows you to gently move the lower ribs anteriorly and medially, making it easier to feel an enlarged spleen

–> usually a spleen cant be felt, it has to double in size to be felt. You also cannot feel the upper border of the spleen

Question 11

(GI) Step 11:

Answer 11

Examination of the kidneys
–> done with both hands

–> the right hand is placed under the costal margin and the left is placed posteriorly in the loin region

–> the fingers of the left hand push the kidney anteriorly which the right hand applies psterior pressure.

–> an enlarged kidney can be balloted between the two hands

–> because the kidneys are retroperitoneal they are difficult to feel and may not be possible to feel the lower pole of the kidney in a thin patient

Question 12

(GI) Step 12:

Answer 12

Other Manoeuvres

• -> Ascites ( accumulation of fluid in peritoneal cavity commonly due to cirrhosis of the liver); presents as buldging planks, flank dullness,
• -> Auscultation of bowel sounds (none in obstruction)
• -> check groin for herniae
• -> digital rectal examination

Question 13

(GI) Step 13:

Answer 13

Question 14

How do you test for the presence of a metabolic flap or asterixis?

Answer 14

• -> ask the patient to hold both arms up with hands extended and arms outstretched.

• -> A flap is preset if there is a F/E movement at the wrists.

Question 15

What does a metabolic flap suggest?

Answer 15

Question 17

What are spider naevi or spider angioma?
