CT scans could predict dangerous leaks after rectal cancer surgery

NCT ID NCT07656974

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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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 a narrowed inferior mesenteric artery (IMA) — seen on routine CT scans — is linked to a higher chance of anastomotic leakage after rectal cancer surgery. Anastomotic leakage is a serious complication where the surgical connection leaks. The study will review CT scans from 123 patients who had rectal cancer surgery to measure the IMA diameter and compare it with leak rates. If a strong link is found, doctors might use this information to decide which patients need extra protection, such as a temporary stoma.

What this could mean

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

What this could lead to
If a link is found, surgeons could use CT scans to identify high-risk patients and take extra precautions to prevent leaks.
What could go wrong
This is an observational study, not a treatment trial. It may find no clear connection, or the results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
