Intraoperative cholangiography (IOC) is recommended to prevent bile duct injury during laparoscopic cholecystectomy.1 However, conventional radiographic IOC in a laparoscopic setting is time-consuming, and insertion of a transcystic tube for contrast-material injection may in itself cause bile duct injury.2 Furthermore, conventional IOC exposes the patient and medical staff to radiation and usually requires a large fluoroscopy machine and additional human resources.3 Recently, we developed a novel fluorescent IOC technique using the intravenous injection of indocyanine green (ICG) to delineate the biliary tract during an open cholecystectomy.4 Herein, we report our initial experience applying fluorescent IOC to laparoscopic cholecystectomy using a newly devised laparoscopic fluorescent imaging system.
Our fluorescent IOC technique is based on the principle that ICG is excreted into bile and that protein-bound ICG emits light with a peak wavelength of approximately 830 nm when illuminated with near-infrared . . . [Full Text of this Article] AUTHOR INFORMATION
