BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard of treatment for symptomatic cholelithiasis. Although intraoperative cholangiography (IOC) is widely used as an adjunct to LC, there is still no worldwide consensus on the value of its routine use. Anatomical studies have shown that variations of the biliary tree are present in approximately 35% of patients with variations in right hepatic second-order ducts being especially common (15-20%). Approximately, 70-80% of all iatrogenic bile duct injuries are a consequence of misidentification of biliary anatomy. The purpose of this study was to assess the adequacy of and the reporting of IOCs during LC. METHODS: IOCs obtained from 300 consecutive LCs between July 2014 and July 2016 were analysed retrospectively by two surgical trainees and confirmed by a radiologist. Biliary tree anatomy was classified from IOC films as described by Couinaud (1957) and correlated with documented findings. The accuracy of intraoperative reporting was assessed. Biliary anatomy was correlated to clinical outcome. RESULTS: A total of 95% of IOCs adequately demonstrated biliary anatomy. Aberrant right sectoral ducts were identified in 15.2% of the complete IOCs, and 2.6% demonstrated left sectoral or confluence anomalies. Only 20.4% of these were reported intraoperatively. Bile leaks occurred in two patients who had IOCs (0.73%) and two who did not (7.4%). CONCLUSION: Surgeons generally demonstrate biliary anatomy well on IOC but reporting of sectoral duct variation can be improved. Further research is needed to determine whether anatomical variation is related to ductal injury.
