Q

The GB serves as a reservoir for ___ that is drained form the hepatic ducts in the liver.

A

bile

33
Q

The common hepatic duct is joined by the cystic duct to form the ___.

A

CBD- common bile duct

34
Q

The main pancreatic duct joins the CBD, and together they open through a small ampulla call the ___ into the duodenal wall.

ampulla of Vater

35
Q

sphincter of Oddi

36
Q

37
Q

List the 2 primary functions of the extrahepatic biliary tract.

A

To take bile from the liver to intestine and regulates flow.

38
Q

Describe the normal function of the GB during digestion.

A

Bile concentrates during fasting. Very little is sent to duodenum when fasting. Food stimulates the sphincter of Oddi to open and the GB to contract, releasing bile to the duodenum for digestion.

39
Q

Bile is the principal medium for excretion of bilirubin ___.

A

cholesterol

40
Q

The ___ from the small intestine stimulate the liver to make more bile. This activates intestinal and pancreatic enzymes.

A

bile salts

41
Q

The sign that indicates an extrahepatic mass compressing the CBD, which can produce an enlarged GB, is called _____.

A

Courvoisier’s sign

42
Q

Sonographically, the CBD lies ___ and to the ___ of the portal vein in the region of the porta hepatis and gastrohepatic ligament.

A

anterior; right

43
Q

The hepatic artery lies ___ and to the ___ of the portal vein.

A

anterior; left

44
Q

To ensure maximn dilation of the GB, the patient should not be given anything to eat for at least ___ hours before a sono.

A

8-12

45
Q

The patient is initially in full ___ with ultrasound.

A

respiration

46
Q

The patient should also be rolled into a deep ____ or upright position (to ensure there are no stones in the GB) in an attempt to separate small stones from the GB wall or cystic duct.

A

decubitus

47
Q

The GB may be described as a ___ oblong structure located anterior to the right kidney, lateral to the head of the pancreas and duodenum.

A

sonolucent

48
Q

The GB commonly resides in a ___ on the medial aspect of the liver.

A

fossa

49
Q

Because of ____ tissue within the main lobar fissure of the liver (which lies between the GB and the right portal vein), this bright linear reflector is a reliable indicator of the location of the GB.

A

fat or fibrous tissue

50
Q

A small ____ fold has been reported to occur along the posterior wall of the GB at the junction of the body and infundibulum.

A

echogenic

51
Q

On a transverse scan, the common duct, hepatic artery, and portal vein have been referred to as the _____ sign.

A

Mickey Mouse

52
Q

To obtain a cross section of the portal triad, the transducer must be directed in a slightly ___ path from the left shoulder to the right hip.

A

oblique

53
Q

On sagittal scans, the the right branch of the hepatic artery usually passes ___ to the common duct.

A

posterior

54
Q

The common duct is seen just ___ to the portal vein before it dips posteriorly to enter the head of the pancreas.

A

anterior

55
Q

When the right subcostal approach is used, the common hepatic duct is seen as a tubular structure anterior to the portal vein. The right branch of the ___ artery can be seen between the duct and the portal vein as a small circular structure.

A

hepatic

56
Q

The most classic symptom of GB disease is ___ pain, usually occurring after ingestion of greasy foods.

A

RUQ

57
Q

A GB attack may cause pain in the ___ shoulder.

A

right

58
Q

The normal wall thickness of the GB is less than ____cm.

A

3

59
Q

List the 6 biliary causes of GB wall thickening.

A

cholecystitis, adenomyomatosis, cancer, AIDS, cholangiopathy, sclerosing cholangitis

60
Q

Clinically the patient with acute cholecystitis presents with what symptoms?

A

acute RUQ pain, positive Murphy’s sign, inspiritory arrest upon palpitation of GB (which may be false positive in a small percentage) fever, leukocytosis

61
Q

The ____ sign is described as a contracted bright GB with posterior shadowing caused by a packed bag of stones.

A

WES- wall echo shadow

62
Q

A fairly rare complication of acute cholecystitis associated with the presence of gas forming bacteria in the GB wall and lumen with extension into the biliary ducts is called ____.

A

emphysematous cholecystitis

63
Q

For gallstones, clinically the patient falls under the five F’s which are:

Q

Explain why the patient’s position should be altered during an ultrasound.

A

To demonstrate movement of stones. Patients can be scanned LLD, right lateral, or upright. Stones should shift to the most dependent areas of the GB. If bile is thick and stones float, the density of the stones and posterior shadow will provide evidence.

65
Q

Describe the factors that can produce a shadow in the GB.

A

acoustic impedence of gall stones, refraction through them and diffraction around them, their size, central or peripheral location, position in relation to the beam or intensity of the beam.

66
Q

_____ may be the result of pancreatic juices refluxing into the bile duct because of an anomolous junction of the pancreatic duct into the distal common bile duct,causing duct wall abnormality, weakness, and outpouching of the ductal walls.

A

Choledochal cysts

67
Q

A hyperplastic change in the GB wall is ___.

A

adenomyomatosis

68
Q

The differential for a porcelain GB would include a packed bag or _____.

A

WES sign- wall echo shadow

69
Q

What is the most notable finding in GB carcinoma?

A

GB wall is markedly abnormal and thickened

70
Q

The most common cause of biliary obstruction is the presence of a ____ or ___ within the ductal system.

A

tumor; thrombus

71
Q

List three primary areas where obstruction occurs.

A

intrahepatic, suprapancreatic, or porta hepatic obstructions

72
Q

An uncommon cause for extrahepatic biliary obstruction as a result of an impacted stone in the cystic duct creating extrinsic mechanical compression of the common hepatic duct is ______.

A

Mirrizzi syndrome

73
Q

____ causes increasing pressure in the biliary tree with pus accumulation.

A

Cholangitis

74
Q

The majority of stones in the CBD have migrated from the GB. Common duct stones are ususally associated with ____.

A

calculous cholecystitis

75
Q

____ within the duodenum may also give rise to a dirty shadow in the RUQ.

A

Air or gas

76
Q

On ultrasound, multiple cystic structures that converge toward the porta hepatis are seen in _____.

A

Caroli’s disease

77
Q

What maneuvers can be performed to differentiate a tumor of the GB from sludge?

A

change patient position

78
Q

Describe clinical signs and sono findings of the patient with acute cholecystitis? Complications?

A

Symptoms- RUQ pain, fever. Findings include- enlarged GB, positive Murphy sign, thick and irregular GB, stones, pericholecystic fluid. Complications- GB rupture, empyema, emphasematous or gangrenous cholecystitis, perforation

79
Q

What anechoic structure surrounds the GB that may lead to confusion during the exam?
