Physical examination algorithm
For accurate diagnostics, it is crucial to follow the correct sequence of examination methods. Violating the algorithm can lead to erroneous conclusions.
- General inspection of the patient.
- Inspection of the abdominal region.
- Percussion (allows for a rough estimate of organ dimensions).
- Palpation of the liver (the primary method, but performed strictly after percussion).
- Examination of the spleen (performed at the very end).
This approach allows the physician to first gather maximum visual information, outline organ borders, and only then proceed to tactile contact.
Systemic masks of liver diseases
Chronic conditions, such as active hepatitis or cirrhosis, can mimic systemic connective tissue diseases. As a result, liver disease may imitate systemic lupus erythematosus, rheumatoid arthritis, or scleroderma.
Key extrahepatic manifestations:
- Articular syndrome: persistent arthralgia or arthritis.
- Vascular disorders: Raynaud's syndrome (pallor, "dead fingers").
- Sicca syndrome (Sjögren's): lack of saliva (xerostomia), dry eyes, multiple caries.
- Fever: in hepatitis, it is non-infectious in nature, unlike the hectic fever with chills typical of purulent cholangitis or abscess.
To confirm primary liver damage in such complex cases, a thorough history taking and biopsy are required.
Cutaneous liver signs and stigmata
External signs allow one not only to suspect hepatobiliary pathology but also to infer its cause.
Specific manifestations depending on etiology:
- Alcoholic liver disease: spider angiomas in the collar region, red palms (palmar erythema), gynecomastia, "alcoholic facies" with giant parotitis (enlargement of the salivary glands), and Dupuytren's contracture.
- Cholestasis (impaired bile outflow): scratch marks from pruritus, hyperpigmentation, as well as xanthelasmas and xanthomas (lipid deposits, often on the eyelids).
- Hepatocellular insufficiency: intense jaundice, hemorrhagic syndrome (petechiae, bruising due to decreased prothrombin synthesis), hepatic fetor (fetor hepaticus), and tremor.
- Chronic hepatitis/cirrhosis: thickening of the terminal phalanges (digital clubbing).
Notably, spider angiomas (telangiectasias) deserve special mention. These are capillary dilations around a central arteriole. Pressing on the center of such a star causes it to blanch. Visually, the phenomenon resembles the pattern on a banknote.
Inspection of the abdominal region
Targeted inspection of the right upper quadrant and epigastrium is most informative in patients with a thin abdominal wall (asthenics).
What can be revealed during visual assessment:
- Asymmetry and bulging: occurs with marked hepatomegaly, large tumors, abscesses, or echinococcal cysts.
- Lagging in respiration: the right half of the abdomen may participate less in the act of breathing.
- Liver pulsation: a pulse-synchronous oscillation caused by blood regurgitation in tricuspid regurgitation.
- Gallbladder bulging: noticeable in dropsy or empyema of the gallbladder.
- Signs of portal hypertension: ascites (against the background of extremity wasting), a protruding umbilicus, and a network of dilated subcutaneous veins ("caput medusae").
Briefly: answers to topical questions
What are the normal liver dimensions according to Kurlov?
Normal liver dimensions according to Kurlov are approximately 9 cm, 8 cm, and 7 cm, depending on the measurement line.
- First dimension — approximately 9 cm (determined along the right midclavicular line).
- Second dimension — approximately 8 cm (determined along the midline).
- Third dimension — approximately 7 cm (determined along the left costal margin).
Along which topographic lines is percussion performed to determine the upper border of the liver?
Percussion to determine the upper border of the liver is performed exclusively along the right midclavicular line. For the remaining dimensions, the upper point is determined conventionally and is not sought by percussion:
- Midline — the upper point is not determined by percussion due to the sternum, but is established by drawing a horizontal line from the upper point of the first dimension.
- Left costal margin — the upper point is not percussed, as it corresponds to the upper point of the second dimension (projected from it).
Sequence rule: Inspection → Abdomen → Percussion → Liver (palpation) → Spleen. Liver palpation is always penultimate, right before the spleen.
Class and exam questions
Why do bruising and bleeding occur in cirrhosis?
Hemorrhagic syndrome occurs because the damaged liver stops synthesizing clotting factors (primarily prothrombin). Additionally, the situation is aggravated by thrombocytopenia associated with hypersplenism.
How to distinguish a spider angioma from a regular rash?
A spider angioma has a central arteriole ("body") and radiating capillaries ("legs"). The main differential sign is that pressing on the center causes the angioma to temporarily blanch and disappear.
What is the mechanism of development of "liver palms" and gynecomastia?
These symptoms are associated with hepatocellular insufficiency. A healthy liver breaks down excess hormones, whereas a failing liver cannot cope, leading to hyperestrogenemia (excess estrogens).
