Background
Common bile duct injuries (BDI) during laparoscopic cholecystectomy (LC) continue to be the source of morbidity and mortality. The reason for BDI is mostly related to the misidentification of the extrahepatic bile duct structures and the anatomic variability. Near-infrared fluorescent cholangiography (NIFC) has proven to enhance visualization of extrahepatic biliary structures during LCs. The purpose of this study was to describe the most important steps in the performance of NIFC.
Methods
In accordance to the most current surgical practice of LC at our institution, a consensus was achieved on the most relevant steps to be followed when utilizing NIFC. Dose of indocyanine green (ICG), time of administration, and identification of critical structures were previously determined based on prospective and randomized controlled studies performed at CCF.
Results
The ten steps identified as critical when performing NIFC during LC are preoperative administration of ICG, exposure of the hepatoduodenal ligament, initial anatomical evaluation, identification of the cystic duct and common bile duct junction, the cystic duct and its junction to the gallbladder, the CHD, the common bile duct, accessory ducts, cystic artery and, time-out and identification of Calot’s triangle, and evaluation of the liver bed.
Conclusions
Routine use of NIFC is a useful diagnostic tool to better visualize the extrahepatic biliary structures during LC. The implementation of specific standardized steps might provide the surgeon with a better algorithm to use this technology and consequently reduce the incidence of BDI.
