Abstract
Objective: To describe our experience of CT (Computed tomographic) Cholangiography examination for detection of choledocholithiasis at the Aga Khan University Hospital (AKUH) Karachi Pakistan.Methods: Seven patients underwent helical CT cholangiography for suspected choledocholithiasis. Iopanoic acid (6 grams) was administered orally 8-12 hours before acquisition of a helical CT cholangiogram. Three-dimensional reconstructions and curved multiplanar reformations were generated from a set of axial source images.Results: Our patients had no adverse reactions to iopanoic acid. The degree of biliary opacification was sufficient to perform three-dimensional and curved planar reformations in 5 patients. In two patients, the biliary tree was not opacified. Both of these studies were considered failures. Findings on CT cholangiography in the remaining 5 patients were the following: cholelithiasis with normal bile duct (n=2), choledocholithiasis (n=1), stone in gallbladder remnant with long cystic duct (n=1) and infiltrating adenocarcinoma of the gallbladder (n=1).CONCLUSION: Spiral CT cholangiography is a safe, non-invasive, and cost effective alternative test and, in a carefully selected patient population can play a role in the diagnostic work-up of patients with suspected choledocholithiasis.
