Q

How should the patient be positioned and exposed prior to starting an abdominal examination?

A
  • the head of the bed should be adjusted to a 45o angle and the patient lies down
  • adequately expose the patient’s abdomen for the examination from the waist up
  • offer a blanket to allow exposure only when required and inform patients that they do not need to remove their bra
  • exposing the patient’s lower legs is helpful to assess for peripheral oedema

57
Q

How is the neck inspected during abdominal examination?

A

the neck is palpated for lymphadenopathy

palpate the supraclavicular fossa on each side, paying particular attention to Virchow’s node on the left for evidence of lymphadenopathy

58
Q

What is Virchow’s node and why is it important to pay particular attention to this area?

A

it is the left supraclavicular lymph node

it receives lymphatic drainage from the abdominal cavity

enlargement of Virchow’s node can be one of the first clinical signs of metastatic intra-abdominal malignancy

how should you be positioned?

A

ask the patient if they are aware of any areas of abdominal pain

if present, these areas should be examined last

kneel beside the patient to carry out palpation and observe their face throughout the examination for signs of discomfort

74
Q

How should the abdomen be palpated?

A
  • light palpation of each of the 9 abdominal regions should be done initially
  • deep palpation of each of the 9 regions is then performed, applying greater pressure to identify any deeper masses

  • masses
77
Q

How should tenderness be recorded?

A

note the abdominal region (s) involved and the severity of the pain

78
Q

What is rebound tenderness?

What can it be associated with?

A

it is said to be present when the abdominal wall, having been compressed slowly, is released rapidly and results in sudden sharp abdominal pain

this is a non-specific, unreliable clinical sign

it can, in some cases, be associated with peritonitis (e.g. appendicitis)

79
Q

What is guarding and what is it associated with?

A

involuntary tension in the abdominal muscles that occurs on palpation

it is associated with peritonitis

(e.g. appendicitis, diverticulitis)

80
Q

What is Rovsing’s sign and what does it indicate?

A

palpation of the left iliac fossa causes pain to be experienced in the right iliac fossa

it was historically indicative of appendicitis

it is not reliable and indicates peritoneal inflammation of any cause affecting the left and/or right iliac fossa

81
Q

If any masses are located during deep palpation, what 5 characteristics should be assessed?

A
  • location
  • size and shape
  • consistency

note which of the 9 abdominal regions the mass is located within

83
Q

How is the mobility of an abdominal mass assessed?

A

assess if the mass appears to be attached to superficial or underlying structures

84
Q

What is a pulsatile abdominal mass suggestive of?

A

a pulsatile abdominal mass is suggestive of vascular aetiology

(e.g. abdominal aortic aneurysm)

85
Q

How is the liver palpated?

A
  • begin palpation in the right iliac fossa, starting at the edge of the superior iliac spine, using the flat edge of your hand (radial side of right index finger)
  • ask patient to take a deep breath and as they begin to do this palpate the abdomen

feel for a step as the liver edge passes below your hand during inspiration

  • repeat this process of palpation moving 1-2cm superiorly from the right iliac fossa each time towards the right costal margin
  • as you get close to the costal margin (1-2cm below it) the liver edge may become palpable in healthy individuals
86
Q

If the liver edge is palpable, what 4 characteristics should be assessed?

A
  • degree of extension below the costal margin
  • consistency of the liver edge
  • tenderness
  • pulsatility
87
Q

Why is the degree of extension of the liver below the costal margin assessed?

A

if it is greater than 2cm then this suggests hepatomegaly

88
Q

Why is consistency of the liver edge recorded?

A

a nodular consistency suggests cirrhosis

89
Q

What might hepatic tenderness suggest?

A

hepatitis or cholecystitis (as you may be palpating the gallbladder)

90
Q

Why is the pulsatility of the liver’s edge assessed?

A

pulsatile hepatomegaly is associated with tricuspid regurgitation

91
Q

Is the gallbladder usually palpable?

What does it suggest if it is?

A

the gallbladder is not usually palpable in healthy individuals

if the gallbladder is palpable, this suggests enlargement secondary to biliary flow obstruction

(e.g. pancreatic malignancy / gallstones)

and/or infection

92
Q

How is the gallbladder palpated?

What does it feel like?

A

palpation of the gallbladder is attempted at the right costal margin, in the mid-clavicular line (tip of the 9th rib)

if it is enlarged, a well-defined round mass that moves with respiration may be noted

93
Q

What does tenderness of the gallbladder on palpation suggest?

What if the gallbladder is not tender?

A

tenderness suggests a diagnosis of cholecystitis

a distended painless gallbladder indicates underlying pancreatic cancer

(particularly if also associated with jaundice)

94
Q

What is Murphy’s sign and how is it assessed?

A
  • position fingers at the right costal margin in the mid-clavicular line at the liver’s edge
  • ask the patient to take a deep breath
  • if the patient suddenly stops mid-breath due to pain, this suggests the presence of cholecystitis
95
Q

How is the spleen palpated?

A
  • palpation begins in the right iliac fossa, starting at the edge of the superior iliac spine, using the flat edge of your hand (radial side of right index finger)
  • ask patient to take a deep breath and as they begin to do this palpate the abdomen with you fingers aligned with the left costal margin

feel for a step as the splenic edge passes below your hand during inspiration (splenic notch may be noted)

  • repeat process of palpation moving 1-2cm superiorly from the right iliac fossa each time towards the left costal margin
96
Q

What would a palpable spleen suggest?

How large would the spleen have to be for it to be able to be felt?

A
  • in healthy individuals, you should not be able to palpate the spleen
  • a palpable spleen at the edge of the left costal margin suggests splenomegaly
  • for the spleen to be palpable at this location it would need to be 3 times its normal size
97
Q

What are the 5 causes of splenomegaly?

A
  • portal hypertension secondary to liver cirrhosis
  • haemolytic anaemia
  • congestive heart failure
  • splenic metastases
  • glandular fever
98
Q

How are the kidneys balloted?

A
  • place left hand behind the patient’s back, below the ribs and underneath the right flank
  • place right hand on the anterior abdominal wall just below the right costal margin in the right flank
  • push your fingers together, pressing upwards with your left hand and downwards with your right hand
  • ask patient to take a deep breath and as they do this feel for the lower pole of the kidney moving down between your fingers
  • if a kidney is ballotable, describe its size and consistency
  • repeat this process on the opposite side to ballot the left kidney
99
Q

In what types of healthy patients are the kidneys sometimes ballotable?

A

the kidneys are not usually ballotable

in patients with a low body mass index, the inferior pole can sometimes be palpated during inspiration

100
Q

What are the causes of bilateral and unilaterally enlarged kidneys?

A
  • bilaterally enlarged, ballotable kidneys occur in polycystic kidney disease or amyloidosis
  • a unilaterally enlarged, ballotable kidney can be caused by a renal tumour
