BACKGROUND: The reported incidence rate of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is 0.3%. However, routine use of intraoperative cholangiography (IOC) is a controversial, due to the additional cost and radiation exposure. The aim of this study was to assess the application of fluorescence cholangiography (FC) in comparison to IOC and to LC without any intraoperative imaging.
MATERIALS AND METHODS: This prospective study included 230 patients undergoing LC in our institution. The subjects were divided into two groups. In the first group, with 170 patients, both FC and IOC were performed following a standardised protocol. In second group, with 60 patients, FC was compared to LC without any intraoperative imaging. The data were then analysed with respect to procedure time and identification of predefined anatomical structures.
RESULTS: The mean age and body mass index in the first group were 54.4 ± 15.7 years and 27.9 ± 5.7 kg/m², respectively. The mean operative time was 67.6 ± 23.3 min. FC was performed more rapidly than IOC (1.5 ± 0.9 vs.7.3 ± 5.0 min) and visualised the cystic duct (DC) in 67.5% of patients and the common bile duct (DHC) in 66.2% of patients before dissection of Calot's triangle. During dissection, DC and DHC were detected in 95.9% and 71.2% of patients, respectively. BMI > 25 kg/m² and male gender significantly reduced the identification rate of DC before dissection of Calot's triangle. Bile leakage from the liver bed after cholecystectomy was found in 3 cases (1.8%) by FC. In 2 patients (1.2%), IOC visualised the DC joining directly to the right hepatic duct. In 1 of these 2 cases (0.6%), the anatomical variation was identified first by FC. Intraductal filling defects were detected in 9 patients (5.3%) using IOC, compared to 1 patient (0.6%) using FC. In the second group, the visualisation rates of DC and DHC were 80.0 and 53.3%, respectively, with FC and 60.0 and 43.3%, respectively, during LC without any imaging. Surgeons confirmed an increase in safety in 70.0% of patients using FC.
CONCLUSION: FC is a simple procedure for non-invasive real-time visualisation of bile duct anatomy during LC. Earlier identification of biliary anomalies and bile leakage increases the operative safety and enables immediate care. In obese patients, FC has limited validity.
