    Abstract:
    BACKGROUND: The partial cholecystectomy may be performed while in complicated laparoscopic cholecystectomy (LC). Biliary anomalies especially the accessory bile duct are established high risk of bile duct injury (BDI) in LC. Laparoscopic resection of residual gallbladder is a challenging procedure and extremely vulnerable to BDI. We report the execution of a laparoscopic resection of residual gallbladder with a communicating accessory bile duct using indocyanine green (ICG) fluorescence cholangiography and the intraoperative cholangiography (IOC). A case that has not been reported previously. PRESENTATION OF CASE: A 29-year-old female with history of laparoscopic partial cholecystectomy was admitted in our hospital. Magnetic resonance cholangiopancreatography (MRCP) revealed the residual gallbladder with an accessory bile duct. Considering the complexity of this patient, we performed a laparoscopic surgery using ICG fluorescence cholangiography. ICG was injected intravenously 1 h before the surgery, the residual gallbladder and the extrahepatic biliary structures including the accessory bile duct were imaged in green in fluorescence imaging that could be recognized clearly. IOC revealed that residual gallbladder communicated with intrahepatic bile duct through the accessory bile duct and drained into the common bile duct (CBD). The entire procedure was performed smoothly and successfully without bile duct injuries. DISCUSSION: Laparoscopic resection of residual gallbladder is a challenging procedure. Fluorescence cholangiography using ICG is regarded as a novel technique that could provide a real-time imaging intraoperative, which allowed to recognize and identify the residual gallbladder and the extrahepatic bile duct. IOC is also important in identifying a communicating accessory bile duct. Under the guidance of them, we completed this laparoscopic surgery. CONCLUSIONS: The combination of fluorescence cholangiography using ICG and IOC have profound significance in complicated LC.
