    ICG-FA is increasingly used to assess bowel perfusion during colorectal anastomosis, with mixed findings from recent trials.

  • 2

    Visual interpretation of ICG-FA shows substantial interobserver variability, making single fluorescence-intensity snapshots unstable for comparison.

  • 3

    Time-intensity kinetics and spatial heterogeneity measures are more reproducible and physiologically meaningful than traditional metrics.

  • 4

    A proposed minimum acquisition and reporting standard aims to enhance consistency in ICG-FA studies for better comparability.

  • 5

    ICG-FA serves as an intraoperative safety measure, but its effectiveness is influenced by multiple factors beyond perfusion alone.
