Fluorescence cholangiography
X-ray cholangiography
After induction of anaesthesia 2.5-7.5 mg of indocyanine green (0.05 mg/kg) is injected intravenously. The operation field is routinely inspected in the fluorescence imaging mode before dissection of Calot´s triangle. During dissection, the fluorescence imaging mode is used when needed, before division of any tubular structure and after division of the cystic duct and artery.
The cholangiography is performed after dissection of the cystic duct by cannulation of the cystic duct with a catheter using either a Kumar- or Olsen grasper. A mobile X-ray C-arm system is used, and the monochrome X-ray image is shown on a separate screen. After satisfactory identification of the extra-hepatic biliary ducts, the intraoperative cholangiography is discontinued and the gallbladder is removed in a standardized manner.
