Clinical Scorecard: Establishing a Standard for Acquisition and Reporting: Advancements in Colorectal Indocyanine Green Fluorescence Angiography Techniques Beyond Fluorescence Intensity

At a Glance

CategoryDetail
ConditionColorectal Indocyanine Green Fluorescence Angiography
Key MechanismsAssessment of bowel perfusion during colorectal anastomosis using ICG-FA.
Target PopulationPatients undergoing colorectal surgery, particularly those at risk for anastomotic leaks.
Care SettingIntraoperative assessment during colorectal surgical procedures.

Key Highlights

  • ICG-FA is increasingly used to assess bowel perfusion during colorectal anastomosis.
  • Pooled randomized evidence supports overall benefit, especially in left-sided and rectal surgeries.
  • Standardization of acquisition and reporting protocols is necessary for reproducibility.
  • Visual interpretation of ICG-FA shows substantial interobserver variability.
  • Emerging metrics like time ratio (TR) may provide more reliable assessments.

Guideline-Based Recommendations

Diagnosis

  • Utilize ICG-FA to evaluate anastomotic perfusion.

Management

  • Implement standardized protocols for ICG-FA acquisition and reporting.

Monitoring & Follow-up

  • Assess physiological status and imaging conditions during ICG-FA.

Risks

  • Consider multifactorial aspects of anastomotic healing beyond perfusion.

Patient & Prescribing Data

Patients undergoing colorectal surgery with risk of anastomotic leaks.

ICG-FA should be viewed as an intraoperative safety measure rather than a standalone prevention strategy.

Clinical Best Practices

  • Adopt a minimum acquisition and reporting standard for ICG-FA studies.
  • Incorporate time-intensity kinetics and spatial heterogeneity measures in assessments.
  • Differentiate between perfusion measurement and perfusion biology in clinical evaluations.
