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 Results may not be published yet.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 tests whether a remote expert can guide a bedside ultrasound to detect free fluid (like blood or ascites) in patients who just had liver surgery. Forty participants will receive a telementored eFAST exam, and its accuracy will be compared to standard CT scans and expert exams. The goal is to see if this approach is reliable enough for routine use.

What this could mean

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

Active substance
Telementored eFAST (ultrasound guided by a remote expert)
What this could lead to
If successful, this could provide a faster, more accessible way to detect internal bleeding or fluid buildup after liver surgery, potentially improving patient monitoring.
What could go wrong
This is a small, early feasibility study with only 40 participants, so results may not apply broadly. The remote guidance may not match the accuracy of an in-person expert.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Patients who have undergone laparoscopic liver surgery at the Oslo university hospital and are within 72 post-surgery Exclusion Criteria: Allergy to ultrasound gel. Patients colonized with ESBL, MRSA and VRE will be excluded due to infection control. Significant postoperative pain that can exacerbated by probe pressure.
