- 5% get what
- 1 in 250 get what
5% chronic diarrhea
1 in 250 bile duct damage
What is acute cholecystitis?
Stone stuck in neck of gallbladder causing inflammation +- ischaemia
(Risk progressing to necrosis if untreated)
Acute cholecystitis pain
- where
- radiates where
- severe or mild
- associated symptoms
- lasts how long

RUQ radiates shoulder tip/back severe assoc fever, N+V, tender lasts longer than biliary colic want to stay still (peritonism)
What is Murphy’s sign? what is it seen in? is it a reliable sign?
Lay 2 fingers over RUQ; pain when PTx inspires as inflamed GB touches examiner’s hand
In acute cholecystitis
Highly specific
What is the Mx of acute cholecystitis?
IV/PO ABx
LAP chole within 1wk of S+S onset
A gallbladder empyema is a complication of acute cholecystitis, what is the Mx of this?
Percutaneous cholecystostomy
What investigation is done for complications of acute cholecystitis?
CT
eg pancreatitis, gallbladder perforation, gallbladder empyema
What is ascending cholangitis?
Bile duct infection secondary to gallstone blocking biliary flow
What is Charcot’s triad?

Percutaneous cholecystostomy
(inserted by an interventional radiologist)
(drains bile to skin)
(also given to patient with severely inflamed gallbladder while waiting for information to settle whilst awaiting surgery)
At how many mm is the bile duct dilated?
9mm
When investigating ascending cholangitis on US, if stones are not seen in the CBD but the duct is dilated or LFTs abnormal, what is done next?
MRCP
‘A stone in the gallbladder pressing on the bile duct causing obstructive jaundice’ describes what
Mirizzi syndrome
Most stones are made of cholesterol, in which locations can they not be seen on CT?
In gallbladder + common bile duct
In a patient with cholecystitis, if they suddenly deteriorate what complication may have arisen? What do you do to diagnose it?
Gallbladder perforation
CT
Mx laparotomy
