This open access paper notes that

  • Low blood supply increases leakage and surgical recurrence in Crohn’s disease,
  • Indocyanine green angiography is useful for evaluating the intestinal blood supply.
  • Blood supply at anastomotic sites was lower in Crohn’s disease than colon cancer.

Conclusion: Intraoperative indocyanine green fluorescence imaging is safe and reproducible for assessing intestinal perfusion prior to anastomosis in patients with colon cancer and Crohn’s disease.
