Biliary Colic or Cholangitis in an Elderly Patient
An 82-year-old woman presents with 2 days of right upper quadrant pain, fever, and jaundice. She has hypertension, atrial fibrillation on apixaban, and mild cognitive impairment. Observations: temperature 38.9 C, HR 112 irregular, BP 102/64, RR 22, SpO2 96% on air. Examination shows RUQ tenderness without peritonism. Bloods: bilirubin 96 micromol/L, ALP 340, ALT 120, WCC 17.8, creatinine 132 (baseline 90), lactate 2.4, INR 1.6. Ultrasound shows a dilated common bile duct of 11 mm with a suspected stone and no intrahepatic duct dilatation; gallbladder is thick-walled with stones. The surgical registrar proposes urgent ERCP. The anaesthetist is concerned about sedation in a frail patient on anticoagulation.
1. How do you risk-stratify and decide the timing and route of biliary drainage?
Read the worked answer
This is ascending cholangitis with sepsis-induced acute kidney injury and a likely choledocholithiasis. Severity assessment drives timing. She has organ dysfunction (renal, tachycardia, possible early hypotension), so this is at least moderate severity and warrants urgent biliary drainage after resuscitation, not elective scheduling. Resuscitation includes oxygen, careful fluid resuscitation with reassessment, blood cultures, and broad-spectrum antibiotics covering gram-negative enteric organisms and anaerobes. Address anticoagulation: apixaban should be withheld, and reversal considered if an invasive procedure is imminent, balancing bleeding risk against the risk of uncontrolled sepsis. For drainage, ERCP with sphincterotomy and stone extraction is first line if available and feasible. Anaesthetic risk is real; options include experienced sedation with airway support, or GA with careful haemodynamic management. If ERCP fails or is unavailable, percutaneous transhepatic drainage is a reasonable temporising measure, with surgery reserved for failure of less invasive options. The judgement is to prioritise decompression within hours, not days, while planning anaesthesia and anticoagulation deliberately.
2. The family asks why she cannot simply have antibiotics and be observed. How do you explain the reasoning and the alternatives?
Read the worked answer
Explain that the infection is caused by a blocked bile duct, so pus and infected bile cannot drain. Antibiotics reduce bacterial growth but cannot relieve the obstruction; without drainage, pressure builds and infection spreads into the bloodstream, which can cause organ failure. Explain the options in plain language: endoscopic drainage through the mouth, percutaneous drainage through the skin, or surgery, each with trade-offs. Be honest that she is frail, that sedation carries risk, and that the team will use the least invasive effective option first. Explain that even with drainage, recovery may be prolonged and that escalation decisions may need to be revisited. Document the discussion and offer the opportunity for a second conversation. This is shared decision-making, not consent by persuasion.
3. Twelve hours later she is confused, BP 88/50, urine output 10 mL/hour, lactate 4.2. What is your management and what does it tell you about the initial plan?
Read the worked answer
This is worsening septic shock with inadequate source control. Immediate priorities: airway and breathing assessment, high-flow oxygen or respiratory support, fluid resuscitation with balanced crystalloid and frequent reassessment, early norepinephrine to achieve MAP at least 65, urinary catheter, repeat lactate and blood gas, and urgent escalation to senior surgery, ICU, and interventional endoscopy. Broad-spectrum antibiotics should be reviewed for adequacy and dosing in renal impairment. Biliary drainage must now be expedited, and if ERCP cannot be achieved promptly, percutaneous drainage should be arranged without delay. The deterioration indicates that the initial plan was too slow or too optimistic about the patient's reserve; the lesson is that in frail elderly patients with cholangitis, drainage should be organised in parallel with resuscitation, not sequentially after it. Reassess goals of care with the family, but do not conflate frailty with futility.
