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 Results may not be published yet.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

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.

Summary

This study tests two types of dissolvable stitches—fast-absorbing and slow-absorbing—to see which one leads to less scarring after surgery. Each patient gets both types on different halves of the same wound, so the comparison is fair. The goal is to find out if slower-absorbing stitches give the skin more time to heal and result in a smoother scar.

What this could mean

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

Active substance
surgical sutures (fast-absorbable Vicryl and slow-absorbable PDS)
What this could lead to
If it works, this could help surgeons choose the best suture type to reduce scarring after skin surgery.
What could go wrong
This is a very small early study with only 20 participants, so results may not apply to everyone. The difference between suture types might be small or not meaningful.
