Ascending cholangitis with septic shock — FFICM MCQ

Correct answer: D — Arrange urgent biliary drainage with ERCP or interventional radiology

The correct answer is D, arrange urgent biliary drainage with ERCP or interventional radiology. This patient has grade III (severe) acute cholangitis by Tokyo Guidelines criteria: biliary obstruction (dilated common bile duct, raised bilirubin and ALP) plus organ dysfunction (septic shock requiring noradrenaline, coagulopathy with INR 1.6, thrombocytopenia). In this setting, antibiotics and fluids alone cannot achieve source control because the obstructed, infected biliary tree continues to seed bacteria and endotoxin into the bloodstream. Current guidance is clear that in severe cholangitis, biliary decompression must be arranged urgently once the patient is stabilised, rather than deferred, as delayed drainage is associated with higher mortality and persistent shock. Why the other options are wrong: C. Wait 72 hours for antibiotics to work: antibiotics cannot clear an obstructed, pus-filled biliary system; delaying drainage in severe cholangitis prolongs septic shock and increases mortality. E. Start antifungal therapy as definitive source control: there is no indication of fungal infection here, and antifungals do not relieve the mechanical obstruction driving ongoing sepsis; they are not a substitute for drainage. B. Plan elective cholecystectomy after recovery: cholecystectomy addresses gallbladder pathology, not the obstructed common bile duct, and an elective approach ignores the immediate need for urgent decompression in a shocked patient. A. Give lactulose for presumed hepatic encephalopathy: there is no evidence of encephalopathy in the stem; the biochemical picture (raised bilirubin, markedly elevated ALP, dilated duct) reflects obstructive cholangitis, not hepatic failure. Key point: severe cholangitis with septic shock is a source-control emergency, ERCP or percutaneous drainage must be arranged urgently regardless of ongoing antibiotics or coagulopathy, which should be corrected but not allowed to delay drainage.

Reference: Tokyo Guidelines 2018 (TG18) for acute cholangitis, endorsed in UK hepatobiliary and critical care practice: severe (grade III) cholangitis requires urgent or emergency biliary drainage as source control, alongside NICE NG51 principles on time-critical source control in sepsis. https://link.springer.com/article/10.1002/jhbp.518
