Abstract:
Objective:To explore the clinical value of indocyanine green (ICG) fluorescence imaging technology in complex laparoscopic cholecystectomy (LC) for real-time imaging of extrahepatic bile ducts to avoid bile duct damage.Methods:The data of 90 patients with complicated gallbladder stones with cholecystitis who underwent LC from November 2018 to May 2019 at Liaoning University of Traditional Chinese Medicine Affiliated Hospital were studied. The patients were divided into the control group and the experimental group based on different imaging methods. The control group underwent conventional LC, and the experimental group underwent LC under guidance of ICG fluorescence imaging technology. ICG 5 mg were injected into a peripheral vein (elbow vein) 12 hours before operation. The pre-LC common bile duct, common hepatic duct and cystic duct recognition rates, time to establish gallbladder triangle, intraoperative blood loss, bile duct injuries and postoperative complications were determined.Results:Of the 45 patients in the experimental group, there were 18 males and 27 females. The age was (60.9±9.3) years. The body mass index (BMI) was (26.2±2.0) kg/m 2. Of the 45 patients in the control group, there were 23 males and 22 females. The age was (57.5±8.7) years. The BMI was (26.7±2.7) kg/m 2. There were no significant differences in the clinical data between the two groups ( P>0.05). In the experimental group, the common bile duct was successfully shown in 40 patients (88.9%) and the cystic duct in 34 patients (75.6%). In the control group, the common bile duct was shown in 13 patients (28.9%) and the cystic duct in 12 patients (26.7%). The time taken for the experimental group to establish the triangle of gallbladder was (33.4±9.0) min. The corresponding time for the control group was (52.7±15.0) min. The intraoperative blood loss was (15.5±5.4) ml in the experimental group and (23.0±15.6) ml in the control group. One patient in the control group, but no patients in the experimental group, had to be converted to laparotomy. The control group had 1 right hepatic duct injury and 1 common bile duct injury. Each group had 1 patient with a sub-xiphoid incision infection. No additional complications were detected after a follow-up of 3 months. The differences in pre-LC common bile duct, common hepatic duct, and cystic duct recognition rates, time to establish the gallbladder triangle, and intraoperative blood loss were significantly different between the two groups ( P<0.05). There were no significant differences in biliary tract injuries and postoperative complications rates ( P>0.05). Conclusion:Early observation of the cystic duct and common bile duct with ICG fluorescence imaging in complex LC can help prevent common bile duct damage and speed up the progress of surgery.
