Background and Objectives Fluorescence imaging using indocyanine green (ICG) is undergoing extensive development. This study aimed to assess the merits of ICG in regard to hepatic surgery. Methods Patients with liver lesions that required a resection were eligible. They received an injection of ICG the day before the surgery. Step 1 allowed assessment of use of the medical device under surgical conditions. Steps 2 and 3 assessed the capacity of the MD to detect known tumorous lesions and to spot a predefined area of the liver following injection of ICG into the portal vein (ICGp). Results The 1st step allowed for validation of the MD use with three patients. Between 04‐2013 and 04‐2015, 45 pts were included (40 eligible) in steps 2 and 3. All of the tumorous lesions (95/119) exhibited fluorescence. Four new metastasis were detected in 3 pts, and two missing metastases in 1 pt. False positive were 22%. The maximal depth for detection by fluorescence was 13 mm. Injection of ICGp allowed the corresponding anatomical area to be identified in 16/20 patients. Conclusion This study confirmed that intraoperative fluorescence is a helpful and relevant tool for the liver surgeon (NCT 01738217).
