Figure 1.
Observation of the liver section plane. On naked-eye observation, the gauze that was pressed against the section plane of the liver was not stained yellow with bile (a). Near-infrared observation showed an indocyanine green fluorescent spot (arrowhead) from the parenchyma of the liver section (arrow) (b). A Z-shaped suture was added to the site of contamination (arrow) in the liver section plane, and it can be seen that the fluorescent spot of gauze disappeared (c).
