What is the management approach for a patient with suspected portal hypertension and cholangitis?

Management of Portal Hypertension with Suspected Cholangitis

In patients with suspected portal hypertension and cholangitis, immediately initiate broad-spectrum antimicrobial therapy while simultaneously pursuing urgent biliary decompression if a dominant stricture is present, as this combination is essential for effective resolution of cholangitis. 1

Immediate Assessment and Management

Cholangitis Management

• Start broad-spectrum antibiotics immediately upon suspicion of cholangitis, before awaiting culture results 1
• Common first-line agents include:
  • Fluoroquinolones (e.g., ciprofloxacin) for mild episodes 1
  • Intravenous cephalosporins or extended-spectrum penicillins with anaerobic coverage for severe cases 1
  • Consider antifungal therapy if no response to antibiotics, as Candida species can be isolated in up to 12% of PSC patients 1

Urgent Biliary Evaluation

• Perform ERCP promptly if there are increases in serum bilirubin, worsening pruritus, progressive bile duct dilatation on imaging, or cholangitis to exclude a dominant stricture 1
• Patients with severe acute cholangitis and dominant strictures require urgent biliary decompression, as mortality is high without treatment 1
• Mandatory pathological sampling (brush cytology and/or endoscopic biopsy) of any suspicious strictures during ERCP to exclude superimposed malignancy 1

Biliary Decompression Strategy

• Biliary dilatation is preferred over stent insertion for dominant strictures 1
• If endoscopic approach unsuccessful, consider percutaneous cholangiography with or without stenting 1
• Prophylactic antibiotics are mandatory for all patients with suspected PSC undergoing ERCP 1

Portal Hypertension-Specific Management

Screening and Surveillance

• Perform endoscopic screening for esophageal varices when there is evidence of cirrhosis and/or portal hypertension, following international guidelines 1
• Platelet count <150 × 10³/dL is a strong predictor of esophageal varices (OR 6.3) 1
• Approximately 36% of PSC patients have varices at diagnosis, with 56% having moderate/large varices 1

Portal Hypertension Complications

• Manage portal hypertension complications according to Baveno/EASL guidelines for advanced chronic liver disease 1
• Use non-selective beta-blockers (NSBBs) to prevent portal hypertension-related decompensation 1
• For high-risk varices with NSBB contraindications/intolerance, use endoscopic band ligation 1
• Combination of vasoactive drugs and endoscopic band ligation for acute variceal bleeding 1

Recurrent or Refractory Cholangitis

Long-term Management

• For recurrent bacterial cholangitis, use prophylactic long-term antibiotics 1
• Avoid antibiotic rotation where possible, as this leads to multiple antibiotic resistances 1
• If rotation necessary, obtain expert multidisciplinary assessment including formal microbiology advice 1

Transplant Evaluation

• Evaluate for liver transplantation in patients with refractory bacterial cholangitis not responding to medical and endoscopic management 1
• Recurrent cholangitis can become the primary indication for liver transplantation when repeated episodes are not controlled by antibiotics 1

Critical Pitfalls to Avoid

• Do not perform invasive biliary imaging procedures (like ERCP) in patients with biliary abnormalities without clear indication, as this increases cholangitis risk 1
• Do not leave biliary stents in situ long-term, as positive bile culture rates reach 98% with stents versus 55% without 1
• Do not delay biliary decompression in severe acute cholangitis with dominant strictures, as mortality is high without urgent intervention 1
• Previous ERCP with or without therapeutic intervention is the highest risk factor for positive bile cultures and subsequent cholangitis 1

Special Considerations

Non-Cirrhotic Portal Hypertension

• Portal hypertension can occur in PSC patients without cirrhosis (approximately 3-8% of cases) due to nodular regenerative hyperplasia or obliterative portal venopathy 1
• These patients may still require portal hypertension management despite absence of cirrhosis 1

Multidisciplinary Approach

• Patients with symptomatic, evolving, or complex disease should be referred for expert multidisciplinary assessment 1
• This is particularly important when considering surgical therapy for dominant strictures refractory to endoscopic/percutaneous management 1
