Score of Sosna et al for Rating Ultrasound Findings of the Gallbladder

Description

Sosna et al used a score to describe changes in the gallbladder identified on ultrasound. This can help identify a patient with significant stone disease. The authors are Beth Israel Deaconess Medical Center in Boston.

Parameters seen on ultrasound:

(1) luminal distention

(2) sludge and/or stones

(3) gallbladder wall

(4) fluid around the gallbladder

(5) common bile duct dilatation

Parameter	Finding	Scores
luminal distention	none	1
	slight	2
	mild	3
	moderate	4
	marked distention	5
sludge and/or stones	clear fluid (neither sludge nor stones)	1
	layered sludge	2
	tumefactive sludge	3
	stones	4
	obstructing stones	5
gallbladder wall	normal	1
	> 3 mm but no edema	2
	> 3 mm with edema	3
	sloughing	4
fluid around the gallbladder	none	1
	pericholecystic fluid and ascites	2
	pericholecystic fluid only	3
common bile duct	< 6 mm	1
	6 - 9 mm	2
	>= 10 mm	3
	"dilated" with stones	4

where:

• The diameter of the common bile duct when dilated with stones is not given.

total ultrasound score =

= SUM(points for all 5 parameters)

Interpretation:

• minimum score: 5

• maximum score: 21

• The higher the score the more likely culture of cholecystostomy fluid will be positive for bacteria.
