What are the diagnostic tests for gallstones?
Ultrasound
Blood tests
Computed tomography
Magnetic resonance imaging
Cholangioresonance
Intravenous cholangiography
Ecoendoscopy
The ultrasound is the first complementary examination to be performed in case of suspicion of choledocholithiasis.
Blood tests can show abnormal liver function in the presence of choledocholithiasis.
Computed tomography is the ideal test for the differential diagnosis of obstructive jaundice.
Magnetic resonance imaging is a non-invasive method that allows the visualization of the bile duct with very high sensitivity and specificity.
Intravenous cholangiography is a simple and inexpensive method that allows radiological exploration of the bile duct using intravenous contrast.
Ecoendoscopy allows the evaluation of possible lesions in the ampulla of Vater, pancreas, and distal common bile duct.
In case of acute abdomen, biochemical tests such as amylase, CPK, ionogram, gasometry, urine, and pregnancy test should be performed.
