Abstract

Fluorescent cholangiography is a technique that enables real-time identification of the extrahepatic duct during surgery, through visualization of fluorescence of indocyanine green (ICG) in the bile following intrabiliary or intravenous injection. Since this technique first originated in Japan in 2008, it has been clinically used to identify the confluence of the left and right hepatic ducts during hepatectomy, the extrahepatic bile ducts during cholecystectomy, and the site of bile leakage on the raw surface of the liver. Especially, fluorescent cholangiography by intravenous injection of ICG is expected to enhance the safety of laparoscopic cholecystectomy, although the fluorescent imaging system for laparoscopic use has not been available. In the experimental studies, novel fluorescent agents and imaging systems have been actively developed, aiming to visualize the deeply-located bile ducts with fluorescent images of blood vessels on the color images.<br>
