Acute obstructive cholangitis

Last edited: 4/16/2026

Overview

Acute obstructive cholangitis (AOC) is a severe inflammatory condition characterized by bile duct obstruction leading to systemic inflammatory response and potential multiple organ dysfunction (MOD). 1

Diagnosis

  • Clinical triad of fever, jaundice, and right upper quadrant pain 1
  • Elevated liver enzymes (ALT, AST) and bilirubin levels 1
  • Arterial blood gas abnormalities indicative of systemic hypoperfusion 1
  • Elevated inflammatory markers (TNF-α, IL-6) 1
  • Imaging studies (e.g., MRCP, ERCP) to confirm biliary obstruction 1
  • Management

  • Urgent biliary decompression via endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC) 1
  • Antibiotics targeting biliary flora (e.g., third-generation cephalosporins) 1
  • Fluid resuscitation to correct hypovolemia and maintain hemodynamic stability 1
  • Supportive care including monitoring for MOD and organ-specific support as needed 1
  • Special Populations

  • Elderly: Increased risk of MOD; careful monitoring and supportive care essential 1
  • Comorbidities: Presence of comorbidities may exacerbate MOD; tailored management required 1
  • Key Recommendations

  • Prompt biliary decompression is critical to prevent progression to MOD (Evidence: Strong 1)
  • Early initiation of broad-spectrum antibiotics is recommended to control infection (Evidence: Strong 1)
  • Aggressive fluid resuscitation should be implemented to manage hemodynamic instability (Evidence: Moderate 1)
