Overview
This lecture provides a step-by-step guide to performing an abdominal examination, including inspection, palpation, percussion, and auscultation, along with relevant clinical signs.
Preparation and Initial Steps
- Wash hands, introduce yourself, confirm patient identity, explain the examination, obtain consent, and check for pain.
- Position the patient at a 45-degree angle and provide appropriate exposure from xiphisternum to symphysis pubis.
Inspection
- Inspect the abdomen for scars, distension, jaundice, cachexia, hernias, and medical equipment.
- Inspect hands for pallor (anemia), palmar erythema (liver disease), and Dupuytren’s contracture (alcohol use).
- Check nails for koilonychia (iron deficiency) and leukonychia (low albumin/liver disease).
- Assess for finger clubbing (ulcerative colitis, Crohn's, liver cirrhosis).
- Look for asterixis (flapping tremor, hepatic encephalopathy).
- Compare hand temperatures and assess pulse.
- Inspect arms for bruising (coagulopathies), excoriations (cholestasis), needle marks, and spider nevi (>3 is pathological).
- Inspect axilla for acanthosis nigricans (diabetes/cancer) and hair loss (malnutrition).
- Inspect eyes for conjunctival pallor (anemia), jaundice, corneal arcus, xanthelasma (hypercholesterolemia), and Kayser-Fleischer rings (Wilson’s disease).
- Inspect mouth for angular stomatitis and glossitis (iron, B12, folate deficiency).
Lymph Node and Chest Inspection
- Palpate supraclavicular fossa for Virchow’s node (abdominal malignancy).
- Inspect chest for spider nevi, gynecomastia, and hair loss.
Auscultation
- Lie patient flat, arms at sides; listen for bowel sounds for up to two minutes.
- Auscultate over renal arteries for bruits; check aortic region as needed.
Palpation
- Ask about pain before palpating; examine tender areas last.
- Palpate all nine abdominal regions lightly, then deeply, watching for pain.
- Palpate liver (start at right iliac fossa), spleen (start at right iliac fossa), and kidneys (bimanual ballotment).
- Palpate abdominal aorta for pulsatile mass (suspect AAA).
- Palpate gallbladder/bladder if indicated (usually not palpable in healthy patients).
Percussion
- Percuss liver and spleen borders from right and left iliac fossae towards costal margins.
- Assess for shifting dullness to detect ascites.
Additional Assessments
- Check for pedal edema (suggests low albumin).
- Suggest further investigations: assess hernial orifices, perform digital rectal exam, examine external genitalia, and consider abdominal imaging.
Key Terms & Definitions
- Asterixis — a flapping tremor seen in hepatic encephalopathy.
- Koilonychia — spoon-shaped nails, sign of iron deficiency anemia.
- Leukonychia — whitening of nails, indicates low albumin or liver disease.
- Spider nevi — small, dilated blood vessels, often due to liver disease.
- Kayser-Fleischer rings — brownish rings around the iris, associated with Wilson’s disease.
- Virchow’s node — enlarged left supraclavicular lymph node, suggests abdominal malignancy.
- Shifting dullness — change in percussion note from resonant to dull, seen in ascites.
Action Items / Next Steps
- Summarize and document findings after examination.
- Wash hands after the procedure.
- Suggest further investigations as applicable (hernial orifices, DRE, genitalia, imaging).
