Study summary

Anastomotic leakage (AL) is a serious complication after surgery for colon cancer, leading to a significant increase in mortality.Intraoperative fluorescence imaging using indocyanine green has proven to be a feasible and reproducible technique for real-time perfusion assessment.

An increasing number of studies are being published on the use of indocyanine green (ICG) fluorescence imaging in colorectal cancer surgery, showing promising results.

Therefore, we propose conducting a multicenter, randomized controlled trial to investigate the potential use of quantitative assessment of near-infrared fluorescence imaging with indocyanine green (ICG) to prevent anastomotic leaks during colorectal surgery.

Study arms

  • Active comparator
    The ICG group

    The ICG group, where, before creating the anastomosis, intestinal blood flow will be assessed using quantitative near-infrared fluorescence imaging using indocyanine green.

    Drug: ICG-guided bowel perfusion assessment

  • Placebo comparator
    The control group

    The control group, where before the creation of the anastomosis, the intestinal blood flow will not be assessed.

    Other: Conventional Bowel Anastomosis group

Interventions

  • DrugICG-guided bowel perfusion assessment

    ICG will be injected before anastomosis is created, to quantitatively assess the perfusion status of the bowel.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Jun 2025; primary completion for Jul 2026, 13 months later.

Of 50 phase 3 interventional studies under Colonic Neoplasms, half reached primary completion within 87 months of starting (the median), counting those still running; a quarter within 48 and three quarters within 128. This study's planned 13 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 25, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
