When you hear the bell ring and you are
directed to enter the examination room, do remember your manners and greet the
examiners with a brief “Good morning” or “Good afternoon”. Never before in the
history of the university was there a need for a “Good night sir”. In the
excitement of the exams, time can be hazy and you may lose track of it. But
stay grounded and always stay in touch with reality. That is why a good night
sleep the day before is essential. You don’t want to be making a fool of
yourself even before the examination begins.
Upon entering the room and after you have
greeted the examiners, your name will be read out and you are supposed to
verify that the candidate name read is indeed your name. After which,
automatically proceed to the examination bed where the patient is seated or
lying down. You will find the examination instructions pasted on the table.
Read it carefully and take note of the patient’s designated name and also the
exam question.
For example, the question may read “Madam A
has abdominal discomfort. Please examine her abdominal system.”
A short reminder on refraining from
addressing patients with “aunty”, “uncle”, “pakcik” or “makcik’. We have been
doing this habitually during our day to day practice and it is customary for us
as this is a respectful way of addressing our senior patients. But for the
purpose of major examinations, please use the patients’ designated names
instead, to sound more formal.
After reading the instructions, proceed
with positioning the patient to prepare for abdominal examination. Patients
should be placed in full supine position whenever possible. The head can only
be supported by one pillow (maximum) but if the patient is able to tolerate
without any pillow, that would be best. Remember to expose the patient
adequately as well. For male patients, if they are consenting, request the
patient to remove the shirt completely. For female patients, perhaps it would
be better to just expose the abdomen from xiphisternum all the way down to the
suprapubic or pubic symphisis region for the sake of the patient’s modesty. For
the purpose of this post, I will begin the examination from general inspection,
then the peripheries before the abdomen itself.
General inspection, look for:
1. Overall patient condition i.e.
restless, in discomfort or comfortable. Take note of any obvious dysmorphism e.g.
Cushingoid appearance etc. and last but not least any obvious skin
discolorations e.g. bronze skin (hemochromatosis or iron overload conditions
e.g. thalassemia), sallow skin (chronic kidney disease may suggest polycystic
kidney disease or obstructive uropathy or failed renal transplant case) or
jaundiced skin.
2. Look at IV drips – blood
product transfusion, antibiotics, dextrose infusion etc that may give a clue to
the underlying abdominal diagnosis
3. Look at CBD bag at the bedside
if any – pay attention to urine colour: tea coloured urine may suggest a liver
or hematological disorder, hematuria may suggest an underlying coagulopathy
(possible liver disorder related)
4. Look at temperature charts at
bedside if any (may indicate an infective diagnosis)
Hand examination (as far as possible ask
the patient to lift their own hands up, you may support the hands once they
have done so). Pay particular attention to the following details:
1. Finger clubbing – lower your
eyes to the nail fold or Lovibond’s angle to look for loss of angle, you may
also do the Schamroth window test by opposing both thumbs or index fingers
together to look for loss of diamond shaped window.
2. Leuconychia – this will indicate
hypoalbuminemia which may be related to the patient’s nutritional status or
underlying chronic liver disease (to differentiate this from pallor, in
leuconychia, the nail bed blanching will not be visible through the nails as
the nails are opacified in leuconychia)
3. Nail bed colour – may hint at
anemia if there is pallor
4. Capillary refill time –
indicator of adequate perfusion
5. Splinter hemorrhages – stigmata
of endocarditis (relevant for the abdominal station as endocarditis may be
associated with splenomegaly)
6. Koilonychia – suggestive of
iron deficiency – indicates underlying chronic blood loss or gastrointestinal
malignancy
7. Symmetrical deforming
polyarthropathies (suggestive of Rheumatoid arthritis) – may be related to the
abdominal station as RA may be associated with splenomegaly in a condition
called Felty syndrome
8. Tendon xanthomas – suggestive
of dyslipidemia (may be associated with Non Alcoholic Fatty Liver Disease
(NAFLD) or Primary Biliary Cirrhosis (PBC))
9. Intrinsic muscle wasting –
indicative of nutritional status (relevant to malabsorption or chronic disease
e.g. GI malignancy)
10. Hepatic flaps – hepatic
encephalopathy (a sign unlikely to be seen in the exams as patients are usually
well and stable). Remember to ask the patient for any pain over the wrists before performing dorsiflexion of the hands and jerking the fingers backwards to stimulate the flapping movements.
Upper Limbs:
1. Bruises/ petechiea – will
suggest an underlying coagulopathy or thrombocytopenia
2. Scratch marks – elevated
bilirubin levels or uremia may cause itching leading to scratch marks
3. Tattoos – may indicate a risk
for viral hepatitis infection
4. Multiple needle prick marks – may
suggest underlying abuse of intravenous substances (risk for viral hepatitis or
retroviral infection)
5. BCG scar – tuberculosis is a
differential for any chronic infection in our part of the world
6. Axillary hair – look for loss
of axillary hair by abducting the shoulders a little (loss of axillary hair is
seen in chronic liver disease, but need to differentiate from patient’s who
regularly shave their armpits)
7. Tendon xanthomas over the
elbows (may indicate underlying severe dyslipidemia)
8. Arteriovenous fistulas – indicate
underlying end stage kidney disease. Need to consider polycystic kidney disease
in the abdominal exam station. And also look out for renal transplantation
scars later on during the examination.
Head and neck:
1. Eyes – look for conjunctiva
pallor and sclera icterus. Also observe for xanthelasma (please do not mention
Kayser- Fleishcer rings as those are only seen using slit lamp examination) and arcus senilis which may indicate underlying hyperlipidemia.
2. Mouth – angular stomatitis
(indicate iron deficiency or vitamin B deficiency), glossitis (B12 deficiency),
oral thrush (immunocompromised state), gingitis and caries (predisposes to
endocarditis which may be associated with splenomegaly, thus making it relevant for the abdominal station), gum hyperplasia (may indicate underlying exposure to drugs like
cyclosporine – an immunosuppressant that is used for renal transplant patients
(relevant to the abdomen station), phenytoin (anti epileptic drug which may
also be relevant to the abdomen station) or acute myeloid leukemia)
3. Neck – look for dialysis
catheters, enlarged cervical lymph nodes (I would suggest examining the
cervical nodes after completing the abdominal examination when you are able to
sit the patient up).
Chest:
1. Spider naevi – bear in mind it
can also be found in normal persons. But if there are more than 3 spider naevi
found, then chronic liver disease should be suspected first.
2. Gynecomastia – look for a disc
like tissue swelling in the retro-areolar region in males. It is usually tender
so be gentle while palpating for it. It may indicate underlying chronic liver
disease but also indicate that the patient may be on certain drugs like
spironolactone. Spironolactone is a common diuretic used for patients with
decompensated liver cirrhosis with ascites.
Abdomen:
1. Symmetry of movement with
respiration – for this step I would take a step or two back and inspect the
anterior abdominal wall while asking the patient to take a deep breath in and
then exhaling. This movement will enable me to look for any asymmetry of
abdominal wall movements. This may indicate or suggest an underlying mass.
2. Peristaltic movements – this
may indicate an underlying bowel obstruction; which is unusual for the medical
examination (so do not look too hard for this sign)
3. Pulsations – visible pulsations
may be relevant for the abdominal examination. A pulsatile mass adjacent to the
midline will alert you of a possible underlying abdominal aortic aneurysm. You
will need to palpate with caution to prevent rupturing the aneurysm.
4. Surgical scars – pay attention
to midline laparotomy scars, laparoscopic scars (most often at the umbilicus
region and at the left or right upper quadrants), peritoneal tapping scars and
appendicectomy scars. Pay close attention to subcutaneous injection scars over
the periumbilical regions which may hint at regular insulin use or iron
chelation therapy use (both of which are relevant to the abdominal system).
5. Visible and dilated veins –
usually caput medusa (may suggest underlying liver cirrhosis with portal
hypertension)
6. Cough impulse – this maneuver
is to examine for possible inguinal hernias. Although this step is included in
the abdominal examination, this may not be so practical for the medical
station.
7. Superficial palpation – this
step is to elicit any abdominal tenderness or guarding which may indicate
underlying peritonism. It is highly unlikely for students to encounter such a
condition in the exams, therefore, I would suggest performing this step by
palpating the abdomen in 4 quadrants instead of 9 quadrants.
8. Deep palpation – this step is
more important as it is intended to identify abdominal masses. Therefore it is
better to perform this step by palpating the abdomen in 9 quadrants.
9. Liver palpation – begin from
the right iliac fossa (RIF) and progress superiorly toward the right subcostal
margin. I would recommend taking control of the patient’s breathing by asking
the patient to breathe in and breathe out on your command at a pace that is
suited to the student. This will allow the student to better appreciate the
movement of any liver that are moving with respiration. When the patient is
inspiring (breathing in), the palpating hand should be kept still awaiting the
inferior liver edge to hit the hand. When the patient is expiring (breathing
out), the palpating hand should move superiorly towards the right subcostal
margin if no liver edge is felt. Once the liver edge is felt, the palpating
hand should keep still to mark the position of the liver edge. Using the left
hand, the student can feel the surface of the liver and its consistency. Remember
to try to get above the mass as well to verify that the mass is indeed the
enlarged liver. After that, the measuring tape should be brought out and
measurements taken from the inferior liver edge to the right subcostal margin
along the right mid clavicular line. Once done, the right hand can feel along
the inferior liver edge to determine if its regular or irregular margins and
ill- or well-defined. This is followed by percussion beginning from the right
iliac fossa, gradually moving superiorly until the position of the palpable
liver mass earlier. The student should take note of the change in percussion
note from resonant to dull over the liver mass. Remember to also percuss the
upper right hemithorax and progress inferiorly towards the right subcostal
margin to identify the superior margin of the liver. Once the percussion note
is dull, that is the superior margin and the measuring tape is brought out
again and measurement taken from the dull point towards the right subcostal
margin along the right midclavicular line. The entire liver span would be a
summation of the distance from the upper margin of liver to the right subcostal
margin and the distance from the right subcostal margin to the inferior margin
of the liver.
10. Spleen palpation – begin from
the RIF and move diagonally towards the left hypochondrium. As per liver
palpation, advance towards the left hypochondrium every time the patient
expires until you feel the splenic tip hitting your fingertips. Once you’ve
felt the splenic tip contacting your fingertips, stop moving your palpating
hand and remain still. Use your left hand to begin feeling the surface and
consistency of the spleen and attempt to get above it. Following which, draw
the measuring tape again and measure the spleen size starting from the left
subcostal margin along the left midclavicular line extending diagonally towards
the splenic tip. Then percuss from the right iliac fossa towards the splenic
mass to appreciate the change in percussion note from resonant to dull upon
reaching the splenic mass. To further verify the splenic mass, percuss also the
Traube’s space. In the event the spleen is not palpable, then percuss the
Traube’s space. If the Traube’s space is resonant, then it is unnecessary to
palpate for the spleen in right lateral position. If the Traube’s space is
dull, then should proceed with turning the patient to right lateral position
and then re-palpate the spleen from the umbilicus towards the left
hypochondrium. Bear in mind, other causes may contribute to a dull Traube’s
space on percussion i.e. left pleural effusion or a stomach mass.
11. Kidney palpation – the kidneys
are balloted to determine if they are enlarged. If there is a mass arising from
the right or left lumbar, the student would be required to approach it like any
lump and bump i.e. palpation of the edges, surface, consistency, measurement of
size in two dimensions, attempting to get above and below the mass and also
percussion. A kidney mass would have overlying resonant percussion note as it
is a retroperitoneal structure and the bowel loops are lying anterior to it.
12. Ascites – if the abdomen is
grossly distended, it is adequate to perform fluid thrill. If the abdomen is
not distended or mildly distended only, then shifting dullness percussion
should be performed to identify any underlying ascites. During shifting
dullness, while the patient is on right lateral position, can take this
opportunity to examine the sacral area for sacral oedema and also inspect the posterior
superior iliac crests bilaterally for bone marrow aspiration scars. After
completing the shifting dullness percussion, it is also possible to palpate for
the spleen in right lateral position if the spleen was not palpable in supine
position (if Traube’s space was dull to percussion note).
13. Inguinal lymphadenopathy – I
would suggest taking the opportunity to examine the inguinal nodes for any
nodal enlargement after turning the patient back to supine position upon
completing the examination for ascites.
Neck:
After completing inguinal node examination,
sit the patient up to examine the cervical nodes. Avoid palpating the jugular chain nodes on both sides at the same time. This is to avoid compressing the carotid sinus simultaneously which may cause vagal syncope.
Respi:
While the patient is sitting up, take the
opportunity to auscultate the lungs if time permits – look for crepitation to
suggest pulmonary oedema or reduced breath sounds to suggest pleural effusion.
These indicate the patient may be fluid overloaded as a result of
hypoalbuminemia or as a complication of underlying chronic liver disease or end
stage kidney failure.
Back:
While the patient is still sitting, move
inferiorly to the sacral area after auscultating the lungs. Examine the sacral
area for sacral oedema as well as look for bone marrow aspiration scars over
the posterior superior iliac crest region. If this step has been performed
earlier, then this step need not be repeated.
Lower limbs:
Lastly, move to the legs and while looking
at the patient, compress the bony prominences over both ankles to look for
pitting pedal oedema.
After completing all the above, offer to
complete your examination by offering to perform:
1. Rectal examination – not every
patient will require this unless indicated. Per rectal examination would
definitely be required if the patient is pale, and the examination is to look
for melena to suggest gastrointestinal hemorrhage.
2. External genitalia examination –
offer to perform this examination if chronic liver disease is in your
differential diagnoses. This examination is basically to look for loss of
secondary sexual characteristics e.g. testicular atrophy or loss of pubic hair
which may be a manifestation of chronic liver disease or in cases of iron
overload (transfusion dependent thalassemias or hemochromatosis) resulting in
pituitary dysfunction.
3. The student may also offer to
perform any steps which the student thinks may contribute to the diagnosis that
was not done during the examination due to time constraints.
Having completed the physical examination,
the next step would be to SUMMARISE the relevant findings that will lead to the
provisional or main diagnosis. After which, remember to offer several relevant
differential diagnoses.
Without a proper set of provisional and
differential diagnoses, it will be difficult to proceed with a proper
discussion on investigations and treatment plan.
Good luck and keep practicing.
CCE.
