Fluorescence Versus Intraoperative Cholangiography in the Visualization of Biliary Tree Anatomy

Patients will received IV injection of ICG intra-operatively, allowing surgeons to view bile ducts under fluorescence imaging using the da Vinci surgical system with fluorescence Imaging system.

Images from virtual cholangiography will be superimposed in real time on images obtained with fluorescence.

Patients will undergo conventional intraoperative cholangiography (with use of radio-opaque dye), allowing surgeons to view bile ducts under Rx imaging.
