Abstract:

Objective To evaluate the clinical value of indocyanine green (ICG) fluorescence imaging for extrahepatic bile duct in laparoscopic cholecystectomy (LC). Methods Clinical data of 30 patients who underwent LC under the guidance of ICG fluorescence imaging technology from Jan. 2019 to May 2019 were retrospectively analyzed. ICG was injected intravenously before surgery, and the common bile duct and cystic duct structure were developed by near-infrared light. Results Among the 30 patients who underwent LC, 27 patients (90%) had their cystic duct and common bile duct successfully developed, two cases had their cystic duct undeveloped and the common bile duct developed, and one case had neither cystic duct nor common bile
duct developed. The operation time of the 30 patients was 35 (27~65) min, the intraoperative blood loss was 3 (0~10) mL, and the postoperative hospitalization time was 3 (2~5) d. The patients recovered smoothly after operation except one case had red and swollen umbilical wound. The remaining patients were followed up for 1 to 5 months without complications. Conclusion Intraoperative ICG fluorescence imaging can achieve early localization of the common bile duct and cystic duct, which can help to visualize the extrahepatic biliary system during LC, and can avoid iatrogenic extrahepatic biliary tract injury caused by unclear indication during operation.
