Quantification of indocyanine-green-enhanced fluorescence with spectrophotometry (O2C®) in low anterior rectal resection: A prospective study

CONCLUSION: This study proves the feasibility and reproducibility of quantifying zones of indocyanine green (ICG)-enhanced fluorescence on the bowel. All O2C® flow measurements that were collected at the zone of optimal fluorescence exceeded 164 AU, thereby adding more evidence to this value as a suggested cut-off parameter in terms of bowel …
