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).
