Ascending cholangitis with septic shock
A 72-year-old man presents with a 2-day history of right upper quadrant pain, fever of 39°C and jaundice. He is confused, blood pressure 95/60 mmHg, heart rate 115/min, respiratory rate 24/min and oxygen saturation 94% on air. White cell count is 18 × 10⁹/L, bilirubin 120 µmol/L, alkaline phosphatase 350 U/L, ALT 90 U/L, creatinine 150 µmol/L and lactate 3.0 mmol/L. Ultrasound shows a dilated common bile duct of 12 mm and gallstones, with no liver abscess. He has type 2 diabetes and has had no previous biliary surgery. The gastroenterologist is not on site until the morning, and the interventional radiology suite is closed. The surgical registrar suggests starting antibiotics and waiting for a routine ERCP in 3 days.
1. What are your immediate resuscitation and antibiotic choices? Include doses and rationale.
Read the worked answer
- Recognition: Charcot triad plus shock and confusion = Reynolds pentad, consistent with acute ascending cholangitis and septic shock.
- Resuscitation: high-flow oxygen, two large-bore IVs, crystalloid 30 mL/kg (reassess frequently in an elderly diabetic), urinary catheter, arterial line, ICU referral.
- Cultures: blood cultures before antibiotics; urine and bile if drained.
- Antibiotics within 1 hour: piperacillin-tazobactam 4.5 g IV every 6–8 hours (adjust for renal function) or ceftriaxone 2 g IV daily plus metronidazole 500 mg IV every 8 hours. If ESBL risk, use meropenem 1 g IV every 8 hours.
- Rationale: cover Enterobacteriaceae, anaerobes and enterococci; biliary penetration is essential.
2. How urgently should biliary drainage be performed, and what options exist if ERCP is unavailable?
Read the worked answer
- Biliary drainage is urgent: within 24 hours, and ideally within 12 hours in septic shock. Waiting 3 days is unsafe.
- First-line: ERCP with sphincterotomy and stent or nasobiliary drain.
- If ERCP is unavailable: percutaneous transhepatic cholangiography (PTC) drainage by interventional radiology; surgical common bile duct exploration is a last resort.
- If no local expertise, transfer to a centre with emergency ERCP after stabilisation.
- Antibiotics alone do not decompress an obstructed infected biliary tree.
3. What would you say to the surgical registrar who proposes waiting 3 days?
Read the worked answer
- Explain that the mortality of cholangitis rises sharply when drainage is delayed, and that antibiotics alone are insufficient.
- Escalate to the consultant surgeon and gastroenterologist now; arrange emergency ERCP or PTC, or transfer.
- Document the discussion and the plan. If the registrar persists, involve the on-call consultant and hospital management.
- Reassess the patient frequently; if worsening, intubate and ventilate and proceed to the least delayed drainage option.
