Ultrasonography of suspected cholecystitis.
Planning
Choice of modality
- Right upper quadrant abdominal ultrasonography of cholecystitis is generally the first exam of choice.[1][2][3]
- Abdominal CT may be used if complications such as perforation or gangrene are suspected.[4] In adults, acute abdominal symptoms that are rather unspecific also indicate CT.
How soon
After 8 hours of fasting in order to distend the gallbladder.[5]
Evaluation
Ultrasound findings suggestive of acute cholecystitis include:[6]
- Gallstones. Further information: Ultrasonography of gallstones
- Pericholecystic fluid
- Gallbladder wall thickening (wall thickness over 3 mm)[7]
- Dilation of the bile duct
- A sonographic Murphy's sign. A sonographic Murphy's sign which is where the patient experiences pain by pressure upon the gallbladder with the ultrasound probe in inspired state.[8][9]
It is also appropriate to perform a general upper abdominal screening.
