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 Results may not be published yet.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.

Summary

This trial compares two minimally invasive procedures—laser ablation and crystallized phenol application—for treating primary uncomplicated pilonidal sinus disease. Adults with this condition are randomly assigned to one of the two treatments. The main goal is to measure pain on the first day after the procedure, with additional outcomes including wound healing time and recurrence at six months.

What this could mean

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

Active substance
laser ablation or crystallized phenol application
What this could lead to
If one method proves less painful and faster to heal, it could become the preferred minimally invasive treatment for pilonidal sinus disease.
What could go wrong
This is a single-center trial with 120 participants, so results may not apply broadly. Both treatments carry risks of infection or recurrence.
