Enhanced magnetic resonance imaging and enhanced computed tomography (CT) revealed a liver tumor (maximum diameter: 120 mm) located on the right lobe and three small lung metastases (Figure 1A). In addition, metastatic lesions in the lung showed regression and became invisible on enhanced CT (Figure 1B).
The resection line was visualized by overlaying images.

Tokyo, Japan)] was administered intravenously and observed by NIR endoscopy (IMAGE1 S 4U RUBINA system; KARL STORZ, Tuttlingen, Germany). The resection line was clearly visualized by overlaying images (Figure 2, Supplementary Video).
(A) We used a water-jet dissector for dissection of the parenchyma. (B) Vessels >5 mm were resected with an ultrasonically activated device after division using a water-jet dissector.
