Objective To summarize the application and progress of the indocyanine green-fluorescence imaging in liver tumor surgery, at the same time, to demonstrate the advantages, limitations, and prospects of this technology. Methods Clinical researches about indocyanine green-fluorescence imaging in liver tumor surgery were collected, to review the introduction and principle of indocyanine green-fluorescence imaginging, and its clinical application of detecting small lesions and demarcating boundaries in liver tumor surgery. Results Indocyanine green-fluorescence imaging had been used in liver tumors surgery. In the aspect of locating the tumors, detecting small lesions, and demarcating boundaries, it had begun to show its unique value. And it was provided to be a new way to reduce tumor recurrence, improve treatment effect, and prolong survival time. Conclusions Indocyanine green-fluorescence imaging is now in the stage of development and promotion, and it has great development potential in technology. But, it also needs advancement in identification ability of benign and malignant lesions, and the depth of detection.
Objective To investigate the value of indocyanine green fluorescence imaging in common bile duct reexploration. Methods The clinical data of 32 patients who underwent open common bile duct reexploration in the Affiliated Hospital of Southwest Medical University from January 2018 to December 2020 were collected retrospectively. All patients divided into the control group (conventional exploration group, 20 patients) and the fluorescence imaging group (using indocyanine green fluorescence imaging, 12 patients) according to the operational manner. The intraoperative and postoperative results of two groups were analyzed. Results The operative time [(165.2±6.9) min vs. (130.8±5.5) min], the time to find extrahepatic bile duct [(43.9±3.8) min vs. (23.1±4.1) min] and the amount of bleeding [(207.7±7.7) mL vs. (127.5±15.3) mL] in the control group were longer or more than those in the fluorescence imaging group (P<0.05). The incidence of postoperative infection in the control group [7 cases (35.0%) vs. 0 cases (0.0%)] and the length of hospital stay [(10.8±2.8) d vs. (7.1±1.3) d] were higher or longer than those in the fluorescence imaging group (P<0.05). There were no significant difference between the two groups in the incidence of postoperative bile fistula [6 cases (30.0%) vs. 2 cases (16.7%)] and the incidence of residual stones [3 cases (15.0%) vs. 3 cases (25.0%), P＞0.05]. Conclusion Indocyanine green fluorescence imaging appears to be a feasible, expeditious, useful, and effective imaging method while performing reexploration.
