| Outline of Final Research Achievements |
Methods: Sixty-two patients with hepato-pancreatic-biliary malignancies were enrolled in this study. We optimized the dose of ICG in the first 15 patients, and evaluated the detection rate for RLN and PAN in the remaining 47.
Results: The optimal administered dose of ICG for detecting fluorescent signals in PAN was 5 mg/mL. However we could detect RLN and PAN fluorescence in only 29 of 42 patients injected with this dose.Conclusion: 5 mg/ml of ICG to visualize lymphatic flow from the hepatoduodenal ligament to PAN using ICG-NIR imaging was failed. Detection rate of RLN and PAN were 69%, respectively. Further improvement for this procedure will be necessary for clinical application.
