Abstract Objective: To investigate the application effect of indocyanine green (ICG) fluorescence imaging in laparoscopic cholecystectomy (LC). Method: A total of 500 patients underwent laparoscopic cholecystectomy admitted to Zaozhuang Municipal Hospital from January 2020 to January 2022 were selected, they were divided into control group and observation group according to surgical methods. The patients in the control group received conventional laparoscopic cholecystectomy and the observation group (n=250) received laparoscopic cholecystectomy under indocyanine green fluorescence imaging technique. The operation time, intraoperative blood loss, gastrointestinal function recovery time, identifiable grade of extrahepatic bile duct, burst time of gallbladder triangle leakage, the number of indwelling drainage tube, the number of conversion to laparotomy, and the incidence of complications were compared between the two groups. Result: The operative time of the observation group was shorter than that of the control group, and the intraoperative blood loss was less than that of the control group (P<0.05). The gastrointestinal function recovery time and the hospital stay of the observation group were shorter than those of the control group (P<0.05). The identifiable grade of extrahepatic bile duct of the observation group was better than that of the observation group, the time of gallbladder triangle leakage of the observation group was shorter than that of the control group (P<0.05). There were no significant differences in the number of drainage tube placement and conversion to laparotomy between the two groups (P>0.05). No bile duct injury occurred in both groups at 6-month follow-up. Conclusion: Indocyanine green fluorescence imaging technique has significant advantages in laparoscopic cholecystectomy, and can play a re-verification role on the disconnected bile duct, in laparoscopic cholecystectomy, the use of indocyanine green fluorescence imaging technique can assist in judging the biliary tract structure of patients, reduce the degree of intraoperative injury, significantly shorten the operation time and reduce intraoperative bleeding, and at the same time, the above advantages are more obvious for less experienced doctors.
