Planning
Choice of modality
- Ultrasonography of gallstones is the investigation of choice. In suspected cholecystitis such as severe and constant pain, see Ultrasonography of cholecystitis.
How soon
- Within a couple of hours if any of the following:
- Atypical symptoms (which may indicate a more serious disease of the biliary tract or abdomen)
- Pain that does not subside on analgesics.
- Suspected pancreatitis. See: Ultrasonography of pancreatitis
- Otherwise, generally 4-8 weeks in Swedish practice.[1]
Evaluation
- Gallbladder: Gallstones are seen as hyperechoic objects, that leave an acoustic shadow. In case of similarity to a polyp (Ultrasonography of gallbladder polyps), turn the patient, making gallstones changing position, while polyps remain in the same place.
- Related structures: Also exclude signs of cholecystitis, mainly pericholecystic fluid, gallbladder wall thickening, dilation of the bile duct, and a sonographic Murphy's sign. Further information: Ultrasonography of cholecystitis.
- Other: It is also proper practice to perform a general upper abdominal screening.
