IM5.8-10 | Liver Disease Clinical Evaluation — Summary & Reflection

KEY TAKEAWAYS

The clinical evaluation of liver disease requires three interlocking skills:

1. Structured history — six domains: current presentation (acute vs chronic, hepatocellular vs cholestatic symptoms); alcohol history (quantify — CAGE, units/day, years, threshold ≥40 g/day for men); drug/herbal history (include Ayurvedic and traditional preparations, latency, dechallenge); viral hepatitis risk factors (parenteral exposures, sexual history, vaccination status — HBV 3-dose, HAV 2-dose, no HCV vaccine); family history (Wilson disease, haemochromatosis, alpha-1-AT deficiency); sexual/social history.

2. Systematic examination — head to toe: General (jaundice, muscle wasting, ascites, asterixis); hands (leuconychia, clubbing, palmar erythema, Dupuytren's); face (scleral icterus, parotid enlargement, xanthelasma, Kayser-Fleischer rings); chest (spider naevi >5 = chronic liver disease, gynaecomastia); abdomen (caput medusae, hepatomegaly span and texture, splenomegaly, shifting dullness + fluid thrill for ascites); legs (pitting oedema, muscle wasting, peripheral neuropathy).

3. Prioritised differential diagnosis — three-question framework: Acute vs chronic? (Chronic signs present?) → Hepatocellular vs cholestatic? (LFT pattern + stool/urine colour) → Aetiological cluster? (Alcohol: AST:ALT >2:1 + history; Viral: serology risk factors; Obstructive: Charcot's triad + elevated ALP; Autoimmune: middle-aged female + AMA/ANA). Priorities: commonest first (HBV/HCV/ALD/NAFLD in India) + most dangerous first (acute liver failure, ascending cholangitis) + most treatable first (Wilson disease, DILI, biliary obstruction).

REFLECT

Think back to Arvind in the opening hook — the 44-year-old with jaundice and abdominal swelling who arrives with no investigation results. After completing this module, what is the specific sequence of questions you would ask first, and why would you ask them in that order? And when you examine him, which sign — if present — would immediately change your differential diagnosis and your urgency of investigation? There is no single 'right' answer, but there is a right process. The value of structured clinical evaluation is not that it produces certainty (it rarely does), but that it produces a defensible, prioritised hypothesis that the subsequent investigations test and refine. The history and examination are not a ritual you perform before the 'real' investigations; they are the core of clinical medicine. This is what it means to be a clinician.
