Reynolds Pentad at 9 pm in a District Hospital

Diagnosis: acute cholangitis from choledocholithiasis (Charcot triad plus septic shock and confusion - Reynolds pentad), with coexisting acute calculous cholecystitis.

All three Tokyo Guidelines diagnostic domains are met:

• A - systemic inflammation: fever 39.2 degrees C, white cell count 19,600/microlitre.
• B - cholestasis: jaundice with bilirubin 5.4 mg/dL, alkaline phosphatase 486 U/L.
• C - imaging: dilated 12 mm common bile duct with calculi, plus a thickened gallbladder wall with pericholecystic fluid.

Severity: Grade III (severe) acute cholangitis. Grade III is defined by organ dysfunction, of which she has at least three:

• Cardiovascular: systolic BP 86 mmHg after fluid resuscitation.
• Neurological: confusion (disturbed consciousness).
• Renal: creatinine 1.6 mg/dL.
• Metabolic/respiratory: lactate 3.4 mmol/L and tachypnoea.

Grade II criteria (white cell count >12,000, fever ≥39 degrees C, age ≥75 years, bilirubin ≥5 mg/dL) are also present but are superseded - one organ dysfunction is enough to make it Grade III, and that changes the urgency of drainage, not just the antibiotic choice.

Why this matters: grade III cholangitis carries substantial mortality and mandates biliary drainage as soon as possible, within 24 hours - medical therapy alone is not treatment. The pericholecystic fluid also tells you there is concomitant cholecystitis, but the life-threatening problem tonight is the obstructed infected bile duct, not the gallbladder.

Hour 0–1 - resuscitate and confirm:

• High-flow oxygen, two large-bore cannulae, urinary catheter, arterial line if available; move to a high-dependency/intensive care setting.
• Balanced crystalloid 30 mL/kg (approximately 1.5–2 L) guided by MAP ≥65 mmHg, urine output, and lactate clearance; start a noradrenaline infusion if MAP is not restored after fluids. Avoid over-resuscitation in an elderly patient - reassess after each 500 mL.
• Blood cultures two sets from different sites, plus full blood count, coagulation, renal and liver function, lactate, lipase. Blood cultures must precede antibiotics but must not delay them by more than minutes.

Hour 0–1 - antibiotics (do not wait for cultures or for ERCP):

• Piperacillin–tazobactam 4.5 g IV every 6 hours - covers E. coli, Klebsiella, Enterococcus and anaerobes, which are the expected biliary flora.
• Acceptable alternatives: ceftriaxone 2 g plus metronidazole, or a carbapenem (ertapenem/meropenem) if there is healthcare exposure or prior ESBL infection.
• Avoid aminoglycosides - she already has an acute kidney injury with creatinine 1.6 mg/dL.
• Adjust to biliary cultures later; duration is typically 4–7 days after successful drainage, longer if bacteraemia persists.

Hour 1–6 - achieve drainage (the definitive step):

• Call the endoscopist in tonight, or transfer. Grade III disease requires biliary decompression within 24 hours; a working-hours-only service is a logistics problem to solve by escalation, not a reason to wait until morning.
• ERCP with sphincterotomy and stone extraction, with a plastic stent or nasobiliary drain if stones cannot be cleared - do not attempt a prolonged complete clearance in a septic patient.
• Correct the INR if bleeding risk is high, but do not delay drainage for a mildly raised INR of 1.4.

Cholecystectomy is not part of tonight's plan - decompress first, operate later.

Alternatives to ERCP, in order of preference:

1. Percutaneous transhepatic biliary drainage (PTBD) under radiology or ultrasound guidance - the standard rescue when ERCP is unavailable or has failed. It decompresses the duct and buys time; a drainage catheter can later be internalised or the patient transferred for definitive stone clearance. Check coagulation and platelets first.
2. Transfer to a centre with 24-hour ERCP - for a grade III patient who is stabilisable, transfer with ongoing antibiotics and haemodynamic support is often better than an 18-hour wait; the decision depends on transfer time and the receiving team's capability.
3. Surgical decompression - open or laparoscopic common bile duct exploration with T-tube drainage - reserved for failure of both endoscopic and percutaneous routes, or when laparotomy is needed anyway.
4. Endoscopic ultrasound-guided biliary drainage - only where local expertise exists.

Take her to theatre tonight if:

• She deteriorates despite resuscitation - rising lactate, increasing vasopressor requirement, or persistent hypotension.
• There is generalised peritonitis, free air, or a suspected perforation - a surgical abdomen.
• PTBD is unavailable or fails and the patient cannot be transferred.
• There is gangrenous or perforated cholecystitis rather than simple cholangitis.

What not to do: urgent cholecystectomy alone without decompressing the common bile duct - the obstructed infected duct is the source, and removing the gallbladder without draining it leaves the sepsis untreated.

After recovery: definitive treatment of the duct stones and cholecystectomy during the same admission once stabilised, or within 6 weeks if comorbidity makes that unsafe, because the recurrence rate of a second attack is high.
