Overview
There are other imaging modalities that can be useful in diagnosing gallstone disease, these include; endoscopic retrograde cholangiopancreatography (ERCP), bile microscopy and oral cholecystography. It should be noted however, that some of these have been replaced by non-invasive, more advanced and less expensive imaging techniques.
Other Imaging Findings
Endoscopic retrograde cholangiopancreatography
- Endoscopic retrograde cholangiopancreaticogram (ERCP) is an invasive procedure that requires technical expertise and often performed by inserting a tube into the common bile duct while the patient is sedated.[1][2][3]
- Contrast material is then injected to allow visualization of the biliary tree.
- Traditionally, ERCP was not only diagnostic but is also therapeutic, so that if a stone was detected, it could be removed in the same sitting.
- The sensitivity of ERCP for choledocholithiasis is estimated to be 80 - 93%.
- ERCP has largely been replaced by MRCP and is now reserved for patients at a high risk of having a common bile duct stone, particularly with cholangitis.
Oral cholecystography
- Oral cholecystography is rarely done since being replaced by the transabdominal ultrasound.[5]
- It is still occasionally used prognostically to evaluate gall bladder function in obese patients on medical dissolution therapy such as ursodeoxycholic acid where a high quality ultrasound cannot be obtained.
