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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether removing extra tissue (the mesentery) during standard Crohn's surgery is safe and helps prevent the disease from returning. About 30 adults with Crohn's disease who are already on biotherapy will undergo this procedure. The main goal is to see if the surgery causes more complications than usual, and if it lowers the chance of inflammation coming back within 6 months.

What this could mean

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

Active substance
ileocolic resection with extended mesenteric resection (surgical procedure)
What this could lead to
If successful, this surgical technique could lower the chance of Crohn's disease coming back after surgery, reducing the need for repeat operations.
What could go wrong
This is a small, early pilot study with only 30 participants, so results may not apply to everyone. The surgery carries standard risks like bleeding or infection, and it's unclear if removing more tissue is truly better than the standard approach.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 30 people

The number the study aims to enrol. It can still change while the study runs.

Started

Sep 2025

Expected to finish

Mar 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Inclusion Criteria: * The patient must have given their free and informed consent and signed the consent form * The patient must be a member or beneficiary of a health insurance plan * Patient with histologically proven Crohn's disease * Patient who has undergone ileocolic resection and whose disease site is accessible to endoscopic follow-up (first or repeat operation) * Patient on anti-TNF α: infliximab or adalimumab (ECCO 2014 recommendation), vedolizumab, ustkinumab, or other biotherapy (e.g. risankizumab) * Patient able to understand, write and read French Exclusion Criteria: * The patient is participating in an interventional study * The patient is under safeguard of justice or state guardianship * Medical treatment other than biotherapies including anti-TNF α (infliximab or adalimumab), vedolizumab, ustkinumab, risankinumab * Contraindication to surgery, such as major cardiovascular comorbidities * Pregnant, breast-feeding or parturient women
