What is the initial management for a patient presenting with jaundice?

Initial Management of Jaundice

Begin with a detailed history, targeted physical examination, and hepatic laboratory profile (total and fractionated bilirubin, AST, ALT, alkaline phosphatase, GGT, albumin, PT/INR, CBC), followed immediately by abdominal ultrasound as the initial imaging modality of choice. 1

Clinical Assessment Framework

History and Physical Examination Priorities

• Duration and pattern of alcohol consumption: Heavy drinking >40 g/day for >6 months suggests alcoholic hepatitis 1
• Medication and herbal supplement review: Drug-induced liver injury is a common cause of jaundice 1
• Risk factors for viral hepatitis: Exposure history, travel, sexual contacts 2
• Abdominal pain characteristics: Right upper quadrant pain with fever suggests cholangitis (Charcot's triad) 1
• Constitutional symptoms: Weight loss, anorexia suggest malignancy 1
• Pruritus: Indicates cholestatic process 3

Laboratory Evaluation Strategy

The fractionated bilirubin level is the critical first step that determines the diagnostic pathway 3, 2:

• Unconjugated (indirect) hyperbilirubinemia: Suggests hemolysis, hematoma resorption, or inherited disorders (Gilbert syndrome, Crigler-Najjar) 4
• Conjugated (direct) hyperbilirubinemia: Indicates hepatocellular disease or biliary obstruction 1

Essential initial laboratory panel 2:

• Total and fractionated bilirubin
• AST, ALT (hepatocellular injury markers)
• Alkaline phosphatase, GGT (cholestatic markers)
• Albumin, PT/INR (synthetic function)
• Complete blood count (hemolysis evaluation)

Severity Assessment for Alcoholic Hepatitis

If alcoholic hepatitis is suspected (AST >50 but <400 IU/L, AST/ALT ratio >1.5, bilirubin >3.0 mg/dL), calculate severity scores 1:

• Maddrey Discriminant Function >32: Predicts high 28-day mortality
• MELD score >20: Predicts high 90-day mortality
• Patients with jaundice and suspected alcoholic hepatitis require blood, urine, and ascites cultures regardless of fever presence 1

Imaging Algorithm

Initial Imaging: Abdominal Ultrasound

Abdominal ultrasound is the recommended initial diagnostic test by the American College of Gastroenterology and multiple other organizations 1:

• Sensitivity for biliary obstruction: 32-100% 1
• Specificity for biliary obstruction: 71-97% 1
• Sensitivity for cirrhosis detection: 65-95% with 98% positive predictive value 1
• Most accurate US finding for cirrhosis: Nodular liver surface, particularly on undersurface (86% sensitivity) 1

Key advantages 1:

• Non-invasive, readily available, no radiation
• Detects biliary ductal dilatation
• Identifies gallstones, liver parenchymal changes
• Normal CBD caliber has 95-96% negative predictive value for choledocholithiasis 1

Important limitations 1:

• CBD stone detection sensitivity only 22.5-75% (distal CBD often obscured by bowel gas) 1
• Cannot always determine cause of obstruction
• Body habitus and bowel gas may limit visualization

Subsequent Imaging Based on Ultrasound Findings

If ultrasound shows biliary ductal dilatation (obstructive pattern) 1:

• CT abdomen with IV contrast or MRCP are appropriate next steps to determine level and cause of obstruction 1
• CT sensitivity for biliary obstruction: 74-96% with 90-94% specificity 1
• MRCP advantages: Superior for depicting biliary anatomy, no radiation, no contrast needed for biliary tree visualization 1
• ERCP: Reserved for therapeutic intervention when stones or malignant obstruction highly suspected, carries 4-5.2% major complication risk and 0.4% mortality 1

If ultrasound shows no biliary dilatation (non-obstructive pattern) 1:

• Confirms medical/hepatocellular cause of jaundice 1
• Further workup guided by laboratory pattern (viral serologies, autoimmune markers, drug history) 3, 2
• MRI with MRCP may be valuable if primary sclerosing cholangitis or primary biliary cirrhosis suspected despite negative ultrasound 1

Critical Management Priorities

Immediate Actions for Severe Cases

Patients requiring hospital admission 1:

• Severe alcoholic hepatitis (MDF >32 or MELD >20)
• Signs of cholangitis (fever, RUQ pain, jaundice)
• Inadequate social/medical support for outpatient management
• Evidence of hepatic decompensation

Infection screening is mandatory 1:

• Obtain blood, urine, and ascites cultures before antibiotics
• Bacterial infections precipitate multi-organ failure in alcoholic hepatitis
• SIRS on admission predicts increased multi-organ failure risk

Nutritional Support

For alcoholic hepatitis patients 1:

• Require 1-1.5 g protein and 30-40 kcal/kg body weight daily
• Consider enteral feeding tube if unable to eat
• Parenteral nutrition alone is inadequate

Medication Considerations

Avoid nephrotoxic drugs including diuretics in alcoholic hepatitis, as acute kidney injury is early manifestation of multi-organ failure 1

Use iodinated contrast cautiously in imaging, as it increases acute kidney injury risk 1

Common Pitfalls to Avoid

• Do not skip fractionated bilirubin testing: This single test determines whether the workup focuses on hemolysis/metabolism vs. hepatobiliary disease 3, 2, 4
• Do not assume ultrasound will detect all CBD stones: Sensitivity is only 22.5-75%, particularly for distal stones 1
• Do not proceed directly to ERCP without cross-sectional imaging: ERCP carries significant complication risk and should be reserved for therapeutic intervention 1
• Do not overlook infection screening in alcoholic hepatitis: Infections are the primary cause of mortality and must be excluded before immunosuppressive therapy 1
• Do not rely on plain radiographs: They rarely provide useful information except for detecting calcified gallstones or pancreatic calcifications 1
