Q

What are examples of benign biliary tract diseases?

A

Biliary atresia

Choledochal cysts

23
Q

What is biliary atresia?

A

congenital

Biliary atresia is a condition in infants in which the bile ducts outside and inside the liver are scarred and blocked. Bile can’t flow into the intestine, so bile builds up in the liver and damages it. The damage leads to scarring, loss of liver tissue and function, and cirrhosis.

24
Q

What are choledochal cysts?

A

A choledochal cyst (CC) or biliary cyst is a congenital or acquired anomaly affecting the biliary tree. It involves the dilation of the biliary tree that could affect the extrahepatic and/or the intrahepatic segments.

25
Q

What are the different categories of biliary atresia

A

Iatrogenic

Gallstone related (Mirrizi’s)

Inflammatory:
Pyogenic
Parasitic
PSC
Pancreatitis
HIV

26
Q

What are examples of inflammatory causes of biliary atresia?

A

Pyogenic
Parasitic
PSC
Pancreatitis
HIV

27
Q

What are the different types of choledochal cysts?

A

type 1, 2, 3, 4A, 4B, 5

28
Q

What are examples of malignant tumours that can cause jaundice?

A

Cholangiocarcinoma
Cancer of the Head of Pancreas

29
Q

What is the name of bile duct cancer?

A

Cholangiocarcinoma

30
Q

What are the broad categories of cholangiocarcinoma?

A

Intrahepatic 6%

Extrahepatic
Hilar (Klatskin 1965) 67%
Distal 27%

Gallbladder Cancer

Ampullary Cancer

31
Q

Which of intra and extra-hepatic cholangiocarcinoma occurs more often?

A

extrahepatic

32
Q

Out of hilar and distal, where do most extrahepatic cholangiocarcinomas occur?

A

hilar

33
Q

What are risk factors for cholangiocarcinoma?

A

Increases with age
Peak at 80 years

Risk factors:
PSC (strong association)
Congenital cystic disease
Biliary-enteric drainage
Thorotrast (contrast)
Hepatolithiasis
Carcinigens: aflatoxins, etc.

34
Q

What is the presentation of cholangiocarcinoma?

A

Obstructive jaundice
Itching
None-specific symptoms

35
Q

What investigations are done for cholangiocarcinoma?

A

Lab
Radiology: USS, EUS, CT, MRA, MRCP, PTC, Angiography, FDG PET
ERCP, Cholangioscopy and Cytology

36
Q

what are the three types of intrahepatic cancer

A

Mass forming
Peri-ductal
Intra-ductal

Surgery is only option

37
Q

What is MRA?

A

use MRA to: identify abnormalities, such as aneurysms, in the aorta, both in the chest and abdomen, or in other arteries.

38
Q

What is MRCP?

A

Magnetic resonance cholangiopancreatography (MRCP) is a special type of magnetic resonance imaging (MRI) exam that produces detailed images of the hepatobiliary stones/tumour/inflammation

39
Q

What is PTC?

A

A percutaneous transhepatic cholangiography is a way of looking at your bile ducts using x-rays. Your doctor puts a long thin needle through the skin and into your liver and bile ducts.

40
Q

How is cytology different from histology?

A

Cytology generally involves looking at a single cell type. Histology is the exam of an entire block of tissue.

41
Q

What is the management of cholangiocarcinoma?

A

Surgical: only potential curative option

Palliative:
Surgical bypass
Stenting (Percutaneous vs Endoscopic)
Palliative radiotherapy
Chemotherapy
PDT
liver transplant (not standard)

42
Q

What can be done for palliative care for cholangiocarcinoma?

A

Surgical bypass
Stenting (Percutaneous vs Endoscopic)
Palliative radiotherapy
Chemotherapy
PDT
liver transplant (not standard)

43
Q

What is PDT?

A

involves administration of a photosensitizing drug with affinity for neoplastic tissue and subsequent selective irradiation with light of a defined wavelength.

44
Q

What is the incidence of gallbladder cancer like?

A

Rare 2-5% of GI cancers

90% existing Gallstones
Aggressive

45
Q

What is the prognosis of gallbladder cancer?

A

poor
Except if detected early
Incidental in gallstones

46
Q

How is gallbladder cancer usually diagnosed?

A

blood tests. scans, like an ultrasound scan (sometimes from inside your body using an endoscope), CT scan, PET scan, MRI scan, or a type of X-ray called a cholangiography. collecting a small sample of cells from the gallbladder (called a biopsy) to be checked for cancer.

47
Q

What does the treatment of gallstone cancer depend on?

A

whether tumour is adenoma vs. adenocarcinoma

48
Q

What is ampullary cancer?

A

Ampullary cancer is a rare type of cancer. It occurs when cancer starts in the part of the body called the ampulla of Vater. The ampulla of Vater is a small opening where the pancreatic and bile ducts (from the liver) connect to the first part of the small intestine (the duodenum)

49
Q

What is the ampulla of Vater?

A

small opening that enters into the first portion of the small intestine, known as the duodenum. The ampulla of Vater is the spot where the pancreatic and bile ducts release their secretions into the intestines.

50
Q

What are the 2 histological classifications of ampullary tumours?

A

adenoma vs. adenocarcinoma

51
Q

What is an adenoma?

A

An adenoma is a benign (noncancerous) tumor.

52
Q

What is an adenocarcinoma?

A

type of cancer that starts in mucus-producing (glandular) cells

53
Q

What are the treatment options for ampullary tumours?

A

Endoscopic excision
Trans-duodenal excision
Pancreatico-duodenectomy

54
Q

What is a pancreatico-duodenctomy?

A

The Whipple procedure, also called pancreaticoduodenectomy, is an operation to remove the head of the pancreas.
