Q

What are we inspecting on the abdomen?

A

Scars, abdo distension (6F’s),
caput medusae (portal hypertension e.g. liver cirrhosis)
Striae (ascite, cushings, malignancy, obesity, pregnancy)
Hernias
Cullens sign: brusing of tissue around umbilicus associated with haemorrhagic pancreatitis
Grey-turners sign: bruising around the flanks associated with haemorrhagic pancreatitis

17
Q

What features of stoma as we looking at?

A

Location, contents, stool consistency and spout

18
Q

How to palpate abdo?

A

Ensure patient lying flat and not in pain, ask to let you know about discomfort

19
Q

What light palpation should you do?

A

all 9 regions looking for tenderness, rebound tenderness (non-specific but can be associated with peritonitis). Guarding e.g. appendicitis and diverticulitis. Rovsings sign: LIF to RIF pain shows peritonitis. Masses

20
Q

What should you look for in deep palpation masses?

A

Location, size and shape, consistency (smooth, hard, irregular, soft). Mobility and if atached to deepere structures. Pulsatility (looking for AAA)

21
Q

Features of liver palpation?

A

Degree of extension beneath costal margin (>2cm = hepatomegaly)
Liver edge consistency (nodular = cirrhosis)
tenderness (suggests hepatitis or cholecystitis)
Pulsatility (pulsatile hepatomegaly associated with tricuspid regurgitation)

22
Q

Hepatomegaly causes?

A 
Congestive Cardiac Failure
tricuspid regurgitation
Hepatitis (inf + non-inf)
Heaptocellular carcinoma
Hepatic metastases
Wilsons disease
haemochromatosis
leukaemia
myeloma
Glandular fever
Primary biliary cirrhosis
Haemolytic anaemia
23
Q

Where to palpate the gallbladde?

A

Right costal margin, in MCL (tip of 9th rib). should be a well defined round mass thta moves with respiration

24
Q

Gallbladder indications?

A

Painful enlarged = cholecystitis

Painless enlarged = pancreatic cancer, biliary tree cancer with Jaundice and no fevercancer (with no fever)

25
Q

What is murphys sign?

A

Palpation of gallbladder during inspiration. If in pain, then positive and likely cholecystitis

26
Q

Causes of splenomegaly?

A 
Portal hypertension secondary to liver cirrhosis
haemolytic anaemia
Congestive heart failure
splenic metastases
glandular fever
27
Q

Causes of enlarged kidensy?

A

Bilaterally enlarged ballotable kidneys is in polycystic kidney disease or amyloidosis.
Unilateral = renal tumour

28
Q

How to assess shifting dullness?

A

percussion for presence of ascites. Percuss till area of dullness located. Then keep fingers on area and ask patient to roll onto their side, wait 30 secs and then percuss area again. If ascites present, area will not be resonant

29
Q

What abdo auscultation?

A

At least two positions:
Normal bowel sounds
Tinkling bowel sounds: typically bowel obstruction
Absent bowel sounds: suggest ileus. at least 3 mins ausculatation for absent bowel sounds

Also bruits

30
Q

Ileus causes?

A

Electrolyte abnormalities and recent abdo surgery

31
Q

What bruits where?

A

Aortic bruits: 1-2cm superior to umbilicus. Here could show AAA
Renal Bruit: 1-2cm superior to umbilicus and lateral to midline. shows renal artery stenosis

32
Q

What other examinations?

A

Lower leg exam for pitting oedema from hypoalbuminaemia e.g. cirrhosis or protein-losing enteropathy. Sacral oedema check

33
Q

What further investigations?

A
  • Check hernial orifices (if rsigns of bowel obstruction)
  • perform DRE (if GI bleed suspicion)
  • External genitalia examination (rule out testicular torsion as cause of referred abdo pain or an indirect inguinal hernia)
34
Q

Budd-chiari syndrome?

A

Congenital or due to venous thrombosis of the hepatic vein causing painful liver enlargement. COCP RF
