CHOLELITHIASIS-INVESTIGATIONS

1. To detect the presence of stones, do an ultrasound (90% sensitive).

2. A normal ultrasound in the presence of normal bilirubin and liver enzymes can reliably exclude common duct stones.

3. The usual procedures used for diagnosing common duct obstruction are MRCP, ERCP, and transhepatic cholangiography.

4. Note: About half of pigment stones are radiopaque, whereas cholesterol stones are radiolucent.
