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 This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This trial explores whether betacyanin, a pigment found in beetroot, can help doctors detect anastomotic leakage — a serious complication where intestinal contents leak after rectal cancer surgery — earlier than current methods. About 120 people undergoing laparoscopic rectal cancer surgery will drink a betacyanin solution daily after their operation. By measuring the pigment in pelvic drainage fluid, researchers hope to spot leaks sooner and also track how well the leak heals. The goal is a simple, low-cost way to improve outcomes after rectal cancer surgery.

What this could mean

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

Active substance
betacyanin (a pigment from beetroot) given as an oral solution
What this could lead to
If it works, this could offer a simple, non-invasive way to catch anastomotic leaks earlier and track healing after rectal cancer surgery.
What could go wrong
This is a small, single-center trial, so results may not apply broadly. Betacyanin's effectiveness as a diagnostic marker is unproven, and the drink itself may cause harmless red discoloration of urine or stool.
