What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study looks at whether preserving the left colic artery during colon or rectal cancer surgery helps keep the remaining colon well-supplied with blood. Surgeons will temporarily clamp the main artery and use a green dye to measure blood flow. The goal is to see if this technique can reduce the risk of anastomotic leaks, a serious complication that occurs in up to 15% of cases. Fifty adults with colorectal or ovarian cancer are being enrolled.

What this could mean

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

Active substance
Indocyanine green dye injection
What this could lead to
If successful, this could lead to a surgical technique that lowers the risk of dangerous leaks after colorectal cancer surgery.
What could go wrong
This is a small, early-phase study with only 50 participants, so results may not apply widely. The dye injection is safe, but the surgical procedure carries standard risks like bleeding or infection.
