Summary
Ultrasound (sonography) cannot reliably predict gallstone calcification for selecting patients for gallstone dissolution therapy. It is only useful for determining gallstone size.
Area of Science:
- Gastroenterology
- Medical Imaging
- Radiology
Background:
- Gallstones are common, and treatment options include surgical and non-surgical approaches.
- Gallstone dissolution therapy is a non-surgical option for select patients.
- Accurate patient selection is crucial for successful gallstone dissolution therapy.
Purpose of the Study:
- To evaluate the utility of radiological and ultrasound (sonography) examination in assessing gallstone calcification.
- To determine if sonography can aid in selecting patients for gallstone dissolution therapy.
Main Methods:
- Eighty-seven unselected gallstones were analyzed.
- In vitro radiological examination was performed.
- In vitro ultrasound (sonography) was performed.
Main Results:
- No significant relationship was found between the degree of gallstone calcification and its demonstration by imaging.
- Sonogram results were influenced by gallstone size, surface contour, and position within the ultrasound beam.
- Ultrasound could accurately determine gallstone size.
Conclusions:
- Sonography is not suitable for selecting patients for gallstone dissolution therapy based on calcification.
- Sonography's primary utility in gallstone assessment is for determining stone size.
