Ascending Cholangitis Flashcards
What is ascending cholangitis?
Bacteria from the duodenum (typically e.coli) ascends into the bile ducts causing infection and inflammation.
What physiological action usually prevents ascending cholangitis?
Bile travelling down the duct flushing it out.
Therefore biliary stasis is a risk factor
What are risk factors of ascending cholangitis?
Gallstones (Four ‘Fs’ - Fat, Female, Fertile, Forty) in the common bile duct preventing flow of bile
Stricture of the common bile duct
What are the risk factors for gallstones?
Female
Obesity (Fat)
Pregnancy (Fertile)
Age (Forty)
What bacteria is most commonly the cause of ascending cholangitis?
Usually enteric (from duodenum):
E. coli
Klebsiella
Enterococcus
What are the symptoms of ascending cholangitis?
Charcot’s Triad - Fever (90%), RUQ pain (70%), Jaundice (60%)*
Triad (20-50%)
*If increased pressure causes bile to leak into blood stream
Septic shock (Hypotension, Confusion) - All 5 = Reynolds’ Pentad
Also raised inflammatory markers
Pale stool and dark urine
What is in Charcot’s triad?
Fever
RUQ Pain
Jaundice
How is the diagnosis made?
Bloods (CRP, ESR, ECC, Bilirubin)
Ultrasound - 1st line
Endoscopic Retrograde Cholangiopancreatography (ERCP)
Treatment?
Rehydration
IV Antibiotics
ERCP after 24-48 hours to relieve any obstruction
How can gallstones be removed?
ERCP suction (diagnostic and therapeutic) Shockwave lithotripsy Cholecystectomy (removal of gallstones - done more for acute cholecystitis)
Are the enteric bacteria responsible e.g. e.coli, gram negative or gram positive?
Gram-negative
What is Charcot’s triad used to detect?
Ascending cholangitis
Ascending cholangitis is defined as baterial infection of what?
The bile duct
What is included in the Reynold pentad of cholangitis?
Charcot triad (RUQ pain, jaundice, pyrexia)
+
Altered mental status
Shock (hypotension)
What intervention can be used both diagnostically and therapeutically?
Endoscopic Retrograde Cholangiopancreatography (ERCP)
