46
Q

True or false: the chemical composition of bile is determined by the stomach then modified by the gallbladder.

A

False - the chemical composition of bile is determined by the liver, and this can be later modified by the gallbladder and biliary epithelium

47
Q

What is choledocholithiasis?

A

Presence of a gallstone in the common bile duct; it is the most common cause of extra-hepatic biliary obstruction

48
Q

What is primary sclerosing cholangitis?

A

A disease of unknown aetiology characterised by an irregular inflammatory fibrosis of both the intra-hepatic and extra-hepatic bile ducts

49
Q

What is cholecystitis?

A

Inflammation of the gallbladder, commonly accompanied by biliary colic (pain) and usually caused by cholelithiasis (gallstone)

50
Q

Describe some biliary tract diseases in general terms

A
  • Cholecyctitis - gallbladder inflammation
  • Cholelithiasis - gallstones
  • Chronic acalculous gallbladder disease - natural movements needed to empty the gallbladder don’t work well
  • Abscesses or gangrene
  • Polyps (growths of tissue) in the gallbladder
  • Congenital gallbladder defects
  • Gallbladder and bile duct tumours
51
Q

Cholelithiasis typically form from ____ or ____.

A

Cholesterol or bilirubin

A

Biliary infection

54
Q

True or false: most people with gallstones never have symptoms

A
55
Q

People with cholelithiasis symptoms typically report…

A

Inflammation of the pancreas with associated escape of the pancreatic enzyme into surrounding tissues; can be mild acute, severe acute, or chronic; most are caused by cholelithiasis and EtOH abuse

59
Q

Describe the pathophysiology of acute pancreatitis

A
  • Exact initial event is unknown but primary cause seems to be escape of pancreatic enzymes into surrounding tissue due to compromised pancreatic function
  • Compromised pancreatic function causes trypsin inhibitor to accumulate and activates the secretions that escape into surrounding tissue, causing inflammation
60

A
  • Severe epigastric pain (may radiate to back)
  • N+V
  • Fever
  • Abdo tenderness/guarding/distension

A

Inflammation of the appendix, usually due to bacterial or viral infection or an obstruction

62
Q

Inflammatory bowel disease is an umbrella term used to describe what kind of disorders?

A

Chronic inflammation of the GIT

63
Q

What is ulcerative clolitis?

A

Inflammation of the lining (mucosa) of the large intestine (colon), usually located in the rectum and lower colon but may involve other parts of the colon. Ulcers form on the surface of the lining and these may bleed. The inflamed lining also produces excessive mucus which sometimes contains pus. Inflammation in the colon reduces its ability to reabsorb fluid from the faeces which causes diarrhoea. Inflammation in the rectum can lead to a sense of urgency to have a bowel movement.

64
Q

What is Crohn’s disease?

A

Crohn’s disease has an autoimmune origin and can be hereditary; it most commonly affects the small intestine and/or colon but can involve any part of the GIT. Within a diseased section the disease can affect all layers of the intestinal wall and can lead to the development of complications specific to this condition:

  • strictures (intestinal obstruction or narrowing of the intestinal wall)
  • abscesses (boils) and skin tags (swollen lumps or ‘flaps’ of thickened skin occurring just outside the anus)
  • fistulae (abnormal channels connecting different loops of intestine to itself or to other body organs)
  • fissures (ulcerated tears or cracks in the lining of the anal canal)
  • malabsorption and malnutrition
65
Q

What is diverticulosis?

A
  • A condition in which diverticula (pouches) form in the wall of the large intestine
  • It is common in elderly pts and is associated with a low fibre diet
  • Inflammation of the diverticula is called diverticulitis
  • Obstruction of the diverticulae can lead to perforation
66
Q

True or false: most people with diverticulosis are asymptomatic

A
67
Q

What is haematochezia?

A

Passage of bright red blood stools from the rectum, commonly associated with lower GIT haemorrhage; not to be confused with malena (stool with blood that appears black/tarry/offensive)

68
Q

What can cause acute liver failure?
