Cholangitis

Background

• Also known as "ascending cholangitis"
• Requires the presence of biliary obstruction and infected biliary tract

Gallbladder anatomy

Causes

• Choledocholithiasis
• Biliary tract stricture
• Compression by malignant disease

Clinical Features

• Charcot's Triad: Fever + jaundice + RUQ pain
  • Occurs in ~50%
• Reynold's Pentad: The triad + altered mental status + hypotension
  • Occurs in <5%
  • Hypotension may be the only presenting sign in elderly patients

Differential Diagnosis

RUQ Pain

• Gallbladder disease
  • Acute cholecystitis
  • Cholangitis
  • Symptomatic cholelithiasis
  • Choledocholithiasis
  • Acalculous cholecystitis
• Peptic ulcer disease with or without perforation
• Pancreatitis
• Acute hepatitis
• Pyelonephritis
• Pneumonia
• Kidney stone
• Pancreatitis
• GERD
• Appendicitis (retrocecal)
• Pyogenic liver abscess
• Fitz-Hugh-Curtis Syndrome
• Hepatomegaly due to CHF
• Herpes zoster
• Myocardial ischemia
• Bowel obstruction
• Pulmonary embolism
• Abdominal aortic aneurysm

Evaluation

Work-up

• Labs
  • Leukocytosis with neutrophil predominance
  • Elevated alk phos and conjugated bilirubin
  • Blood cultures
• Imaging
  • RUQ Ultrasound
    • Dilatation of CBD ( > 6mm) and presence of choledocholithiasis
    • May miss small CBD stones and in acute cases CBD may not have had time to dilate
• ERCP
  • Should be obtained to confirm the diagnosis and for possible intervention

Management

• Aggressive volume replacement
• Broad-spectrum parenteral antibiotics covering gram negatives, gram positives, and anerobes
  • Piperacillin/tazobactam OR ampicillin-sulbactam OR (ceftriaxone + metronidazole)
• Emergent ERCP

Disposition

• Admit
