What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access

Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This pilot study tests whether a special dye and near-infrared camera can help surgeons see blood flow in tissue flaps used for reconstruction after gynecologic cancer surgery. Fifteen women will receive an ICG dye injection during surgery, and the surgeon will use the images to decide if any changes are needed. The goal is to see if this technique improves surgical planning and outcomes.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ICG (indocyanine green) dye injection
What this could lead to
If successful, this imaging technique could help surgeons make better decisions during reconstruction, potentially reducing complications like poor wound healing.
What could go wrong
This is a very small pilot study (15 people) with no control group, so results may not apply broadly. The dye can cause allergic reactions in rare cases.
