Essential Facts

What are some common causes of biliary leak?

Usually occurs most commonly post biliary tract surgeries or obstruction
Laparoscopic method is associated with a higher rate of bile duct injury than open cholecystectomy.
Other Causes: liver transplant or trauma
Patient Presentation

Scan Information

Slow leaks typically seal spontaneously. One should repeat cholescintigraphy at a later time to ensure resolution.
You may need to delay views beyond 60 mins to accurately locate the leak 
Faster leaks may require surgical intervention
While U/S and CT can detect fluid collections, it is with cholescintigraphy that one is able to determine if the fluid is biliary in origin
