Jaundice with cholestatic pattern points to cholangitis and urgent biliary drainage need.
Side by side
Right upper quadrant pain with fever and positive Murphy sign without jaundice favors acute cholecystitis.
Fever, jaundice, and right upper quadrant pain with cholestatic labs indicates acute cholangitis.
Cystic duct obstruction causes gallbladder inflammation and secondary bacterial infection risk.
Common bile duct obstruction with bacterial ascent causes infected biliary stasis and sepsis risk.
Ultrasound shows gallstones, gallbladder wall thickening above 3 mm, pericholecystic fluid, and sonographic Murphy sign with mild bilirubin change.
Cholangitis often has bilirubin above 2 mg/dL, alkaline phosphatase elevation, leukocytosis, and common bile duct dilation over 6 mm with possible hypotension in severe disease.
The trap
Treating cholangitis like isolated cholecystitis with antibiotics alone delays source control and worsens sepsis. Persistent fever, jaundice, and hypotension should trigger urgent ERCP for decompression.
The repair move
Next best step: start broad-spectrum IV antibiotics such as piperacillin-tazobactam 4.5 g every 6 hours, draw blood cultures, and arrange urgent ERCP for biliary decompression in cholangitis. For uncomplicated cholecystitis, give antibiotics and perform early laparoscopic cholecystectomy during index admission.

CoreA 48-year-old man has fever, right upper quadrant pain, jaundice, and hypotension. Ultrasound shows common bile duct dilation. What is the next best step in management?
Show answer and explanation
Answer: A. Start IV antibiotics and arrange urgent ERCP. Acute cholangitis is a biliary sepsis syndrome requiring immediate antibiotics and urgent biliary drainage.
Why the other choices are tempting
- B. Wrong. Delayed elective surgery misses urgent decompression need.
- C. Wrong. Antacids do not treat biliary obstruction or sepsis.
- D. Wrong. Untreated cholangitis can rapidly progress to shock.
- E. Wrong. Cardiac testing is unrelated to this acute hepatobiliary emergency.

Quick answers
What is the fastest way to tell Cholecystitis from Cholangitis?
Jaundice with cholestatic pattern points to cholangitis and urgent biliary drainage need.
What is the key clue for Cholecystitis?
Right upper quadrant pain with fever and positive Murphy sign without jaundice favors acute cholecystitis.
What is the key clue for Cholangitis?
Fever, jaundice, and right upper quadrant pain with cholestatic labs indicates acute cholangitis.
What is the common trap with Cholecystitis vs Cholangitis?
Treating cholangitis like isolated cholecystitis with antibiotics alone delays source control and worsens sepsis. Persistent fever, jaundice, and hypotension should trigger urgent ERCP for decompression.
