Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older undergoing colo-rectal anastomosis who consent to participate.

Probably not a fit

Patients for whom the endoscopic oxygen tool does not change intraoperative decisions or who do not experience issues related to perfusion.

What this trial studies

This observational study investigates a novel endoscopic imaging system that displays tissue oxygen saturation during colo-rectal anastomosis. Researchers will compare real-time oxygen data with standard perfusion assessment to see if oxygen levels can predict healing and reduce complications. Participation involves adults undergoing colorectal anastomosis at Vanderbilt University Medical Center, with intraoperative ICG-FA and endoscopic StO2 imaging. The study is sponsored by Vanderbilt with collaboration from FujiFilm HealthCare Americas and does not assign a treatment.

Why it matters

Potential benefit: If successful, real-time oxygen information could help surgeons make better decisions to promote healing and potentially reduce leaks.

How similar studies have gone: Prior approaches to assess tissue perfusion (like ICG-FA) have helped in some settings, but this endoscopic oxygen-monitoring method is a novel approach.
