A

No, most are asymptomatic (10-30% of local population have gallstones)

3
Q

What problems can symptomatic gallstones cause? (6)

A

ColicCholecystitisCholangitisJaundicePancreatitisBowel obstruction (gallstone ileus)

4
Q

What is biliary colic?

A

term used to describe a type of pain related to the gallbladder that occurs when a gallstone transiently obstructs the cystic duct and the gallbladder contracts

5

Pigment

7

Primary bile duct stones (choledocholithiasis)

8
Q

What are the features of biliary colic?

A

Gradual build up pain in RUQ (when it eases it leaves a bruised/ aching feeling for a few days - can also cause epigastric pain)Radiates to back/ shoulderAssociated with indigestion/ nausea

9
Q

Does acute cholecystitis cause gallbladder distension?Does chronic cholecystitis cause gallbladder distension?

A

Acute = distendedChronic = not distended

10
Q

When does gallstone pain tend to come on?

A

After eating a big fatty meal

11
Q

How are gallstones diagnosed?

A

USCT scanMRCP/ ERCPHIDAEUS

12
Q

What is a HIDA scan?

A

stands for hepatobiliary iminodiacetic acid scan, creates pictures of your liver, gallbladder, biliary tract and small intestine

13
Q

What is the treatment of biliary colic? (5)

A

Pain killersLow fat diet/ lose weight if obeseObserve in 3-6 monthsIf the patient is getting recurrent episodes of pain consider elective cholecystectomyIf patient unfit, try to dissolve gallstones with ursodeoxycholic acid

14
Q

Treatment of acute cholecystitis? (5)

A

IV antibiotics and IV fluidsNil by mouthUS to confirm diagnosisUrgent cholecystectomy (asap) ORInternal cholecystectomy depending on how inflamed the gall bladder s (antibiotics and come back in 3 months)

15
Q

What complications of gallstones occur when the stone migrate into the CBD? (3)

A

JaundiceCholangitisAcute pancreatitis

16
Q

What is the difference between biliary colic and cholecystitis?

A

When the stone(s) passes into the cystic duct it causes pain and is called biliary colicIf this occurs for a prolonged period of time, it causes gallbladder inflammation (cholecystitis)

17
Q

What is cholangitis?

A

Inflammation of the bile duct system that is usually related to a bacterial infection - usually caused by a bloackage

18
Q

What symptoms suggest a common bile duct pathology? (5)

A

ItchNauseaAnorexiaJaundiceAbnormal LFTs

19
Q

What does ERCP stand for?

A

Endoscopic retrograde cholangio pancreatography

20
Q

What is ERCP used for?

A

Diagnosis and treatment of pancreatic and bile duct problems e.g. gallstone removal

21
Q

How can stones within the CBD be removed?

A

ERCPLaparoscopicallyOpen surgery

22
Q

How is acute pancreatitis due to gallstones treated?

A

CholecystectomyERCP/ ES if frail

23
Q

What is gallstone ileus?How does it form?

A

Small bowel obstruction due to gallstone impacted in distal ileum Fistula forms between the gallbladder and duodenum allowing a large gallstone to pass into the small intestine causing obstruction (moves down the SB causing intermittent colic, present with distal SB obstruction)

24
Q

What is colic?

A

form of pain that starts and stops abruptly. It occurs due to muscular contractions of a hollow tube (colon, ureter, gall bladder, etc.) in an attempt to relieve an obstruction by forcing content out.

25
Q

How is gallstone ileus treated?

A

Urgent laparotomySB enterotomy to remove stoneInterval cholecystectomy in 3 months (if the patient is old and frail the stone is removed and there is not usually a cholecystectomy)

26
Q

What type of patients does gallstone ileus normally occur in?

A

Elderly women

27
Q

How do patients with cholangiocarcinoma usually present? (6)

A

JaundiceWeight lossAnorexiaLethargy50% = lymph node metastases20-30% = peritoneal metastases

28
Q

Staging/ assessment of cholangiocarcinoma?

A

Duplex USCT/ ERCP/ PTCMRI/ MRCP/ MRA

29
Q

what is PTC?

A

Precutaneous transhepatic cholangiography - 1dye delineates the biliary tract on the x-ray images and reveals any significant abnormalities

30
Q

What is MRA?

A

Magnetic resonance angiography

31
Q

What is the only chance of cure of cholangiocarcinoma?

A

Surgical resection (nile duct and liver resection)

32
Q

what palliative treatment can be given for cholangiocarcinoma/

A

Biliary stent (ERCP/ PTC insertion)
