Acute Cholangitis Flashcards
Define acute cholangitis
inflammation and infection of the biliary tree (bile ducts) secondary to obstruction
*The term ascending cholangitis refers to the ascension of bacteria from the small intestines to the biliary tree
What are the causes/risk factors of acute cholangitis?
• Gallstones being dislodged and trapped in the common bile duct –choledocholithiasis.
• Gallstone risk factors:
- Female
- Fat
- Fertile (Pregnancy)
- Forty
• can occur secondary to CBD obstruction by cancers and via iatrogenic strictures of the CBD
• Gut bacteria like E. Coli, Klebsiella and Enterococcus are the most common causative organisms –they are allowed to ascend the CBD without being ‘flushed away’ due to biliary stasis
What are the signs and symptoms of acute cholangitis?
- RUQ pain
- fever
- jaundice
- confusion
- hypotension/shock
What investigations are carried out for acute cholangitis?
- FBC - high WCC
- CRP/ESR - high
- Amylase - raised if blockade lower
- LFT - obstructive Jaundice – ALP and GGT increased – alkaline phosphatase and gamma glutamyl transferse
- U&E - kidney dysfunction
- Blood Culture - sepsies
IMAGING
• XR – stones
• MRCP – non calcified stones – magnetic resonance cholangiopancreatography.
• Contrast CT/MRI - cholangitis
What is the management for acute cholangitis?
- Resus – if in septic shock
- BS AB – metronidazole (DNA) and cefuroxime or ciproflaxin (B-Lactams)
- Endoscopic biliary drainage.
What are the complications of acute cholangitis?
- pyogenic liver abscess
- cholangiolytic abscess (usually small and multiple) in the liver
- longstanding recurrent cholangitis (eg, Asiatic cholangitis)
- acute renal failure
