BackgroundThe purpose was to evaluate the efficacy of near-infrared fluorescent cholangiography (FC) in real-time visualization of the biliary tree during elective laparoscopic cholecystectomy.MethodsFifty consecutive elective laparoscopic cholecystectomies were performed with fluorescent cholangiography. FC was performed at three time points: following exposure of Calot's triangle, prior to any dissection; and after partial and complete dissection of Calot's triangle.ResultsThe cystic duct (CD) was identified successfully by FC in 43 of 50 patients (86%) and in 45 of 50 patients (90%) before and after Calot's dissection respectively (p > 0.05). The common hepatic duct (CHD) and the common bile duct (CBD) were identified successfully in 12 of 50 patients (24%) and in 33 of 50 patients (66%) before Calot's dissection respectively and in 26 of 50 patients (52%) and in 47 of 50 patients (94%) after complete Calot's dissection (p = 0.007 and p = 0.001, respectively). Significant differences were observed for CBD visualization rate, in relation to BMI after Calot's dissection (p < 0.05) and history of cholecystitis, before Calot's dissection (p = 0.017). No bile duct injuries were reported.ConclusionFluorescent cholangiography can be considered as a useful tool for intra-operative visualization of the biliary tree during laparoscopic cholecystectomies.Copyright © 2017 International Hepato-Pancreato-Biliary Association Inc.
