Overview
Patients who present with right upper quadrant pain are suspected of having gallstone disease. The patients symptoms are usually accompanied by a normal physical examination and normal laboratory results including those for leukocytosis and pancreatic enzyme levels. Typically, an evaluation will begin with a transabdominal ultrasound (TAUS) since it is the most sensitive modality for detecting gallstones.
Diagnostic Study of Choice
Gold standard/Study of choice:
- Transabdominal ultrasound (TAUS) is the gold standard test for the diagnosis of gallstone disease.
- The following result of transabdominal ultrasound is confirmatory of gallstone disease:
- Solitary or multiple stones in the gallbladder or another site within the biliary tree
- Sludge or gravel seen within the gallbladder
- The transabdominal ultrasound should be performed when:
- The patient presented with symptoms/signs abdominal pain, jaundice and fever
- Investigations:
- Among patients who present with clinical signs of gallstone disease, the transabdominal ultrasound is the most specific test for the diagnosis.
- Gallstones appear as echogenic foci that cast an acoustic shadow and exhibit gravitational dependence.
- Gravel has a similar appearance to stones and are also echogenic and cast shadows.
- Sludge is echogenic but does not cast shadows.[1][2][3][4]

Diagnostic results
The following result of transabdominal ultrasound is confirmatory of gallstone disease:
- Solitary or multiple stones in the gallbladder or another site within the biliary tree.
- Sludge or gravel seen within the gallbladder
Sequence of Diagnostic Studies
The transabdominal ultrasound should be performed when:
- The patient presented with symptoms/signs of biliary colic or jaundice or fever as the first step of diagnosis.
- A positive result is the visualization of stones detected in the patient, to confirm the diagnosis.
Diagnostic Criteria
- There is no particular established diagnostic criteria for gallstone disease.
- Diagnosis is based upon history, symptoms and possibly, gallstone detection with transabdominal ultrasound.
