Overview

Transabdominal ultrasound is the initial test of choice for the diagnosis of acute cholecystitis. Findings on an ultrasound diagnostic of acute cholecystitis include thickened gallbladder, gallstones or sludge, and pericholecystic fluid.

Ultrasound

  • Transabdominal ultrasonography is the initial test of choice for the diagnosis of acute cholecystitis and gallstones.[1][2][3][4][5]
    • Findings on an transabdominal ultrasonography diagnostic of acute cholecystitis include:
    • Acalculous cholecystitis may only show a distended gallbladder

Calculous Cholecystitis

  • Acute calculous cholecystitis is diagnosed radiologically by the presence of
    • Thickening of gallbladder (5mm or greater)
    • Pericholecystic fluid
    • Probe tenderness (ultrasonographic Murphy's sign)

Acalculous Cholecystitis

The ultrsound based diagnostic criteria from multiple studies for acalculous cholecystits is as follows.[6]

Criteria Diagnosis
Major 3.5 to 4 mm (or more) thick wall (if at least 5 cm distended longitudinally with no ascites or hypoalbuminemia)
Pericholecystic fluid (halo)/subserosal edema
Intramural gas
Sloughed mucosal membrane
Minor Echogenic bile (sludge)
Hydrops = distension greater than 8-cm longitudinally or 5-cm transversely (with clear fluid)

Diagnosis: 2 major or 1 major and 2 minor (most studies have favored the diagnostic triad: wall thickness, sludge, hydrops).

Advantages of ultrasound

  • Advantages of ultrasound include:
    • Noninvasive
    • Quick and readily available
    • Relatively inexpensive

Limitations of ultrasound

  • Limitations of ultrasound include:
    • Poor visualization with intraluminal gas between probe and gallbladder
