Reynolds pentad (Charcot triad plus confusion and hypotension) means severe cholangitis: this is a biliary emergency needing urgent drainage and often critical care.

Diagnosis

  • Charcot triad: fever or rigors, jaundice, RUQ pain
  • Raised bilirubin, ALP and GGT (obstructive picture), raised inflammatory markers
  • Dilated common bile duct with a stone or stricture on USS or MRCP

Causes

  • Choledocholithiasis (commonest)
  • Benign stricture or malignancy (pancreatic, cholangiocarcinoma)
  • Post-ERCP or stent blockage

Grade I (mild)

  • Charcot triad, responds to treatment
  • IV antibiotics
  • Elective biliary drainage

Grade II (moderate)

  • High-risk markers, no organ failure
  • ERCP drainage within 48 h
  • Close monitoring

Grade III (severe)

  • Organ dysfunction (Reynolds pentad)
  • Resuscitate, critical care
  • Urgent biliary drainage

Cholangitis bundle

1
1. Sepsis care
Blood cultures then IV antibiotics within 1 hour per local policy (cover Gram-negatives and anaerobes). Fluids, and vasopressors or critical care if not responding.
↓
2
2. Imaging
USS first for duct dilatation and stones. MRCP if the diagnosis or anatomy is uncertain and the patient is stable.
↓
3
3. Biliary drainage
ERCP for stone extraction and stenting: urgently if severe or not responding, otherwise within 24 to 48 h. Percutaneous (PTC) drainage if ERCP fails.
↓
4
4. Support and definitive care
Correct coagulopathy before intervention. After recovery, cholecystectomy for gallstone disease; treat strictures or malignancy.

Severity (Tokyo-style) markers

  • Moderate: high WCC, high fever, age, bilirubin, low albumin
  • Severe: organ dysfunction (hypotension, altered GCS, renal, hepatic, haematological)
  • Severe disease needs urgent drainage

Pitfalls

  • Waiting for MRCP before starting antibiotics in sepsis
  • Delaying ERCP in a deteriorating patient
  • Operating on an unstable septic patient (drain first)
  • Missing a blocked stent as the cause
