Hepatobiliary emergency
Cholangitis
Acute cholangitis is biliary infection with potential for rapid sepsis and organ failure. Management hinges on immediate resuscitation and antibiotics, severity assessment, and timely biliary drainage when obstruction persists or disease is severe.
Recognition
Identify acute cholangitis as biliary infection with systemic risk
Do not require classic symptom complexes before initiating a sepsis-oriented evaluation.
Acute cholangitis is a life-threatening infection of the biliary tract. Clinical recognition should integrate jaundice, fever or chills, and right-upper-quadrant pain with laboratory evidence and imaging findings suggestive of biliary obstruction or infection.

Charcot triad and Reynolds pentad are historically important but have limited diagnostic sensitivity; their absence should not defer treatment in a patient with suspected biliary sepsis.

Escalate immediately for hypotension, altered mental status, organ dysfunction, or other features of sepsis; these findings indicate a high-risk presentation in which delayed biliary decompression may be harmful.

First hours
Stabilize and start empiric antimicrobial therapy before source control
Management should proceed in parallel rather than sequentially.
Early recognition, fluid resuscitation, broad-spectrum antibiotics, and biliary intervention have improved outcomes in acute cholangitis. ScienceDirectScienceDirectThe Emergency Medicine−Focused Review of Cholangitis Obtain diagnostic studies and cultures when feasible without delaying antimicrobials or urgent drainage in unstable patients; the supplied sources do not provide a validated U.S. empiric regimen, dose, or treatment duration.
Antibiotic selection should therefore follow local biliary-infection pathways, prior culture data, recent antimicrobial exposure, health care exposure, renal function, allergy history, and the anticipated drainage procedure. This article does not specify drug doses because the supplied evidence does not support regimen-level recommendations.
Resuscitate as for sepsis, with frequent reassessment of hemodynamics, mental status, oxygenation, urine output, and evolving organ dysfunction. BMJ+1BMJAcute cholangitis - Symptoms, diagnosis and treatmentScienceDirectThe Emergency Medicine−Focused Review of Cholangitis
Obtain early gastroenterology/endoscopy and, when appropriate, interventional radiology or surgical consultation for anticipated biliary decompression. NEJM+1NEJMEndoscopic Biliary Drainage for Severe Acute CholangitisScienceDirectThe Emergency Medicine−Focused Review of Cholangitis
Do not use improvement in laboratory values alone as a substitute for reassessment of ongoing obstruction or need for source control. This operational point is based on the central role of drainage in severe disease. NEJM+1NEJMEndoscopic Biliary Drainage for Severe Acute CholangitisScienceDirectThe Emergency Medicine−Focused Review of Cholangitis
Source control
Use biliary drainage to control obstruction-associated severe cholangitis
Drainage addresses the obstructed infected biliary system when medical therapy alone is insufficient.
For severe acute cholangitis caused by choledocholithiasis, endoscopic biliary drainage has been shown to be a safe and effective initial measure for control of the acute episode. NEJMNEJMEndoscopic Biliary Drainage for Severe Acute Cholangitis ERCP-based therapy is therefore central when endoscopic access is feasible and prompt decompression is needed.
Stone-directed definitive management may follow stabilization. In a reported management approach for gallstone cholangitis, ERCP with endoscopic sphincterotomy was followed by interval laparoscopic cholecystectomy. JAMAJAMAManagement of Gallstone Cholangitis in the Era ... The supplied sources do not establish a universal timing target for ERCP, specify a preferred endoscopic technique for every obstruction, or support recommendations on post-drainage antibiotic duration.
Prioritize urgent drainage in severe disease, especially with sepsis physiology or organ dysfunction. BMJ+2BMJAcute cholangitis - Symptoms, diagnosis and treatmentNEJMEndoscopic Biliary Drainage for Severe Acute CholangitisScienceDirectThe Emergency Medicine−Focused Review of Cholangitis
Use multidisciplinary planning when ERCP is unavailable, unsuccessful, or anatomically impractical; the supplied sources do not provide comparative evidence to rank alternative drainage methods.
After biliary instrumentation, monitor for recurrent infection and procedure-related complications; in PSC, risk is particularly relevant when stents remain in place. BMJBMJBritish Society of Gastroenterology and UK-PSC guidelines ...

Chronic cholangiopathy
Recognize cholangitis in primary sclerosing cholangitis
PSC changes the interpretation of laboratory tests and procedural risk.
Cholangitis is a common complication of PSC. Infection may be segmental and can occur without a significant change in baseline liver biochemistry, so clinical assessment and evaluation for a relevant stricture or other biliary complication are important. BMJBMJBritish Society of Gastroenterology and UK-PSC guidelines ...
Previous ERCP, therapeutic intervention, and especially retained biliary stents are risk factors for bacterobilia and cholangitis in PSC. BMJBMJBritish Society of Gastroenterology and UK-PSC guidelines ... A patient with PSC and suspected cholangitis should be managed with early specialist involvement because the differential includes clinically significant stricture and cholangiocarcinoma.
Refer clinically suspected cholangiocarcinoma in PSC for specialist multidisciplinary review. BMJBMJBritish Society of Gastroenterology and UK-PSC guidelines ...

After stabilization
Reassess response and address the cause of obstruction
Disposition depends on physiologic trajectory and adequacy of source control.
Continue close reassessment after antibiotics and drainage for hemodynamic improvement, resolution of organ dysfunction, and evidence that biliary source control is adequate. Severe cholangitis requires a level of monitoring capable of managing sepsis and rapidly escalating organ support.

Common questions
Does absence of Charcot triad exclude acute cholangitis?
No. Classic symptom complexes have poor sensitivity. Diagnose using the overall clinical syndrome, laboratory findings, and imaging evidence of biliary disease, and do not delay treatment in a patient with suspected biliary sepsis. ScienceDirect+1ScienceDirectThe Emergency Medicine−Focused Review of CholangitisOxford AcademicDiagnostic Imaging of Suspected Acute Cholecystitis and ...
When is biliary drainage most urgent?
Urgency is highest with severe disease, particularly hypotension, altered mental status, multiorgan failure, or other sepsis physiology. Endoscopic biliary drainage is an effective initial intervention for severe cholangitis due to choledocholithiasis. BMJ+2BMJAcute cholangitis - Symptoms, diagnosis and treatmentNEJMEndoscopic Biliary Drainage for Severe Acute CholangitisScienceDirectThe Emergency Medicine−Focused Review of Cholangitis
Can PSC-associated cholangitis occur with stable liver tests?
Yes. PSC-related infection may be limited to small hepatic segments and may not produce a significant change in baseline liver biochemistry. Prior ERCP and retained stents further increase infectious risk. BMJBMJBritish Society of Gastroenterology and UK-PSC guidelines ...
What surveillance is considered for hepatobiliary cancer in PSC?
AGA expert review advises considering ultrasound, CT, or MRI, with or without CA 19-9, every 6 to 12 months for cholangiocarcinoma and gallbladder-cancer surveillance in adult PSC.
