Background
- Also known as "ascending cholangitis"
- Requires the presence of biliary obstruction and infected biliary tract
<translate>
Anatomy & Pathophysiology
- Gallstones are classified as cholesterol stones and pigmented stones (black and brown), and are present in approx 20% of females and 8% of males in the United States
- These stones cause the majority of all biliary tract problems, and depending on where the stone become impacted, specific problems occur.
- Bile flows out the gallbladder, down the cystic duct into the common bile duct, and ultimately into the 1st portion of the duodenum.
</translate>
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 + AMS + hypotension
- Occurs in <5%
- Hypotension may be the only presenting sign in elderly patients
Differential Diagnosis
RUQ Pain
- Gallbladder disease
- Pancreatitis
- Acute hepatitis
- Pancreatitis
- GERD
- Appendicitis (retrocecal)
- Pyogenic liver abscess
- Bowel obstruction
- Cirrhosis
- Budd-Chiari syndrome
- GU
- Other
- Hepatomegaly due to CHF
- Peptic ulcer disease with or without perforation
- Pneumonia
- Herpes zoster
- Myocardial ischemia
- Pulmonary embolism
- Abdominal aortic aneurysm
Diagnosis
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
- RUQ Ultrasound
- 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
- Emergent ERCP
Disposition
- Admit
