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). 1Diagnosis
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 1Management
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 1Special Populations
Elderly: Increased risk of MOD; careful monitoring and supportive care essential 1
Comorbidities: Presence of comorbidities may exacerbate MOD; tailored management required 1Key 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)References
