A 71-year-old woman presents with a 3-week history of intermittent right upper quadrant pain, now constant for 12 hours with fever of 38.8°C, jaundice and confusion. Blood pressure 88/54 mmHg. Bilirubin 84 micromol/L, alkaline phosphatase markedly raised. Ultrasound shows a dilated common bile duct with stones. What is the most appropriate management?

1. Antibiotics alone with reassessment in 48 hours Wrong. Antibiotics cannot sterilize an obstructed biliary tree, and 48 hours in septic shock is not an available timescale.
2. Laparoscopic cholecystectomy within 24 hours as the primary intervention Cholecystectomy will be needed once she recovers, to prevent recurrence, but the immediate need is decompression of the duct.
3. Percutaneous cholecystostomy Drains the gallbladder, not the obstructed common bile duct. Percutaneous transhepatic cholangiography is the alternative if ERCP fails or is unavailable.
4. Urgent open cholecystectomy Wrong operation for the immediate problem. The obstruction is in the common bile duct, and a major operation in a septic, shocked patient carries far higher risk than endoscopic drainage.
5. Resuscitation, broad-spectrum antibiotics and urgent biliary decompression by ERCP correct Correct. She has Reynolds pentad, Charcot's triad of fever, jaundice and right upper quadrant pain plus hypotension and confusion, indicating suppurative cholangitis. The infected obstructed system must be drained urgently; antibiotics alone will not clear infection behind an obstruction.

The point: Charcot's triad is cholangitis; Reynolds pentad adds hypotension and confusion and means suppurative cholangitis with high mortality. Resuscitate, give antibiotics, decompress urgently. Definitive cholecystectomy follows once recovered.
