Study published in Surgical Endoscopy – To compare indocyanine green dye fluorescence cholangiography (ICG-FC) with intra-operative cholangiography (IOC) in minimal access cholecystectomy for visualization of the extrahepatic biliary tree. Seven studies including 481 patients were included. Five studies, comprising 275 patients reported higher CD (RR = 0.90, p = 0.12, 95% CI 0.79–1.03, I2 = 74%) and CBD visualization rates (RR = 0.82, p = 0.09, 95% CI 0.65–1.03, I2 = 87%) by ICG-FC. Four studies, comprising 223 patients, reported higher CD-CBD junction visualization rates using ICG-FC compared to IOC (RR = 0.68, p = 0.06, 95% CI = 0.45–1.02, I2 = 94%). Four studies, comprising 210 patients, reported higher CHD visualization rates using ICG-FC compared to IOC (RR = 0.58, p = 0.03, 95% CI 0.35–0.93, I2 = 91%).
Conclusion – ICG-FC is safe, and it improves visualization of CHD (common hepatic duct).
