[The role of fluorescent cholangiography in preventing biliary tract injury and finding bile leakage].

The study investigated the clinical value of fluorescence cholangiography using indocyanine green (ICG) in laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) in preventing bile duct injury (BDI) and detecting bile leakage. A total of 300 patients who underwent fluorescent navigation LC and LCBDE in the Second Department of General Surgery, Shengjing Hospital Affiliated to China Medical University from June 2020 to September 2022 were selected as the research objects for observation and analysis. There were 114 males and 186 females, and aged (50.7±14.0) years with the body mass index (BMI) of (23.6±1.6) kg/m². All 300 cases of fluorescence navigation surgery were successfully completed, of which 5 patients received fluorescence-guided LCBDE and primary suture. The results showed that the application of fluorescence cholangiography with ICG can effectively avoid and detect the occurrence of BDI and bile leakage. Meanwhile, it is reasonable to hypothesize that ICG can be used for rapid localization and the final check to prevent the recurrence of bile leakage when bile leakage is suspected in the second operation.
