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.
