Summary
Peritoneoscopy as an aid in intravenous injection of indocyanine green (ICG) was clinically
evaluated.
Hepatic parenchyma was stained after intravenous injection of ICG, while interstitial
connective tissue, fatty deposition and hepatoma tissue were not. Regenerative hepatic
cell mass including dark reddish patchy marking (Shimada's code No. 7) and semispherical
areas of regeneration or nodules (Shimada's code No. 8) was well stained and clearly
contrasted. There were some cases of chronic active hepatitis, in which liver surface
showed spotty staining at sites expected to become regenerative nodules in the future,
in contrast to being judged as “no abnormal findings” peritoneoscopically. On the
other hand, periportal reddish marking (Shimada's code No. 4) representing piecemeal
or bridging hepatic cell necrosis was not stained.
