What may you find on USS? - 1 - What if it is chronic? - 1

How may you elicit Murphy’s sign?

What may suggest there are stones in the CBD?

A

Abdo USS

4 hrs - will show distended gallbladder

Thick-walled gallbladder
It will be shrunken

Q

Acute cholecystitis - Investigations:

What type of imaging should be done if the USS shows dilated CBD and obstructive LFT’s are failing to improve?

What can be done if the previous is inconclusive?

A

MRCP - magnetic resonance cholangiopancreatography

Provides detailed images of your liver, gallbladder, bile ducts, pancreas and pancreatic duct.

An endoscopic US - EUS

A special endoscope uses high-frequency sound waves to produce detailed images of the lining and walls of your digestive tract and chest, nearby organs such as the pancreas and liver, and lymph nodes.

Q

Acute cholecystitis - Investigations:

For cystic duct obstruction, HIDA scan can be done. What does it involve?

What other scan be done if there are complications?

A

Also called cholescintigraphy or hepatobiliary scintigraphy, is an imaging test used to view the liver, gallbladder, bile ducts, and small intestine.

The scan involves injecting a radioactive tracer into a person’s vein.

CT scan

17
Q

Acute cholecystitis - Management:

Non-operative - 2

Because recurrences are common, what is offered to patients?

What is done if there are CBD stones? - 2

What is a percutaneous cholecystotomy tube (PCT) and why is it used? - 2

A

Supportive Rx - fluids and analgesia
ABs IV

Laparoscopic cholecystectomy

ERCP pre-op or intra-operatively bile duct clearance

For drainage for the urgent treatment of perforation
If the patient unfit for surgery

18
Q

Acute cholecystitis - 3 complications:

Infarction - what is this called and what may it lead to?

Gallbladder empyema - what is another name for it? what is it?

Chronic cholecystitis - what could this lead to?

A

Gangrenous cholecystitis leading to perforation
Leads to peritonitis and high mortality

Gallbladder empyema (aka suppurative cholecystitis)
Gallbladder lumen is filled and distended by purulent material (pus).

Repeated episodes leads to fibrosed and shrunken gallbladder

19
Q

What should be done if there is worsening LFT’s with obstructive jaundice with CBD stones?

A

ERCP with sphincterotomy with biliary trawl (cutting open sphincter allowing easy passage of bile)

20
Q

Chronic cholecystitis:

What makes it chronic?

Other S+S?

Rx?

A

Chronic inflammation

Abdominal discomfort
DIstention 
Nausea 
Flatulence 
Fat intolerance

Same as acute - just not as quickly

21
Q

Acute cholangitis:

What is it?

What imaging can cause it?

What else may cause it?

What is it also known as?

What is the main difference between acute cholangitis vs acute cholecystitis?

A

Infection of the bile duct

ERCP

Biliary malignancy

Ascending cholangitis

You do not get tenderness in acute cholangitis as the biliary ducts are not close enough to the skin to press on them

22
Q

Acute cholangitis - clinical features:

What are the 3 parts of Charcot’s triad (all 3 present in 60% of cases)

A

RUQ pain
Obstructive jaundice
Rigors

23
Q

Acute cholangitis - Investigations:

Bloods and why? - 2

Imaging - 2

A

FBC - raised WBC
LFTs - Raised BR, alk phosphate and GGT

USS
MRCP

24
Q

MRCP vs ERCP

A

A major feature of MRCP is that it is not a therapeutic procedure, while in contrast ERCP is used for both diagnosis and treatment. MRCP also does not have the small but definite morbidity and mortality associated with ERCP.

25
Q

Acute cholangitis - Management:

Initial for infection

What is done once stable

What are 2 ways CBD stones can be dealt with if they cannot be retrieved? - 2

What is the last resort?

A

IV and fluids

ERCP once stable

Sphincterotomy and stone clearance
Stenting

Cholecystectomy and CBD clearance

26
Q

Gallstone ileus:

What is it?
CLUE - stone that pass through the sphincter of Odi unlikely to….

Where does it happen?

What would you see on AXR? - 2

A

A large gallstone that erodes through the gallbladder into the duodenum causing small bowel obstruction

The narrowest point in small bowel - 2 feet proximal to the ileocecal valve

Dilated loops of bowel and air in the biliary tree (entered through the fistula

27
Q

Laparoscopic cholecystectomy:

Where is the port put in for gallbladder removal?

Why is it better than open?

A

Umbilicus

Shorter stay
Faster recovery
No difference in mortality or complications though

28
Q

Laparoscopic cholecystectomy:

General complications of abdominal laparoscopic surgery:

  • why might you get cardiorespiratory strain?
  • why does it need longer training and more equipment?
A

Surgical pneumoperitoneum which reduces venous return - may be harder for patients with heart or lung disease

It is more difficult compared to open - you might also need to convert to open if it is not possible

29
Q

Laparoscopic cholecystectomy:

Specific complications of laparoscopic surgery:

  • Why are people with bleeding disorders contraindicated?
  • Injury of what? - 2
  • What may be missed?
  • Where may an abscess form?
A

It is harder to deal with intraoperative bleeding (e.g cystic or hepatic artery)

CBD injury
Bowel injury

Missed CBD stones

Sub-hepatic
