Presentation
Post-cholecystectomy evaluation of the biliary system.
Patient Data
Normal opacification of the intra and extra-hepatic biliary channels are noted.
No filling defect is noted within the common bile duct. No stenosis or abnormal dilatation of the common bile duct is seen. No evidence of biliary leakage.
Normal opacification of the duodenum is noted.
Case Discussion
Post-operative cholangiography is routinely performed 7-10 days after biliary surgery. 20-30ml of non-ionic water-soluble contrast media is injected through T-tube into the biliary system. The contrast should be injected slowly into the tube, as injection with high pressure can result in cholangiovenous reflux and septicemia in cases with biliary obstruction. Care should also be taken not to inject air bubbles, as it may mimic calculi.
