The Value of CT Cholangiography in Primary Sclerosing Cholangitis

NCT00588458 · Status: WITHDRAWN · Phase: PHASE2 · Type: INTERVENTIONAL

Last updated 2015-04-28

No results posted yet for this study

Summary

The reason for this study is to see if a new radiologic technique called computerized tomographic cholangiography (CT cholangiography) could be helpful to demonstrate the bile ducts features and measure the amount of space of bile duct canals that should be filled with bile fluid. It may be useful to find out how well these findings correlate with the previously known clinical predictors in term of the clinical outcomes that will happen in the future for patients with primary sclerosing cholangitis (PSC).

Conditions

  • Primary Sclerosing Cholangitis

Interventions

PROCEDURE

CT cholangiography

Cholografin 20ml will be diluted in 100 ml of normal saline and infused over 30 minute time interval. Following the infusion of the cholografin, morphine (0.04 mg/kg) will be administered to contract the sphincter of Oddi and improve bile duct distension and visualization. Thirty minutes following the administration of morphine a test scan (CT cholangiography) will be performed through the liver to determine if there is adequate biliary excretion. The test scan will consist of 10 mm thick image obtained through the mid liver. If there is evidence of biliary excretion, high-resolution images will be performed through the liver and bile ducts. The axial images will be reconstructed into maximum intensity projection models and volume rendered models that can be viewed in 3-dimension.
